Description

The present invention relates to a technology for inspecting products in a production line for component mounting boards.

In product production lines, product inspection equipment is placed in intermediate and final processes of the line to detect defects and sort out defective products. For example, in a production line for component mounting boards, there is generally a process of printing cream solder on a printed wiring board (printing process), a process of mounting components on the board printed with cream solder (mounting process), and a process after component mounting. It is known that the method includes a step (reflow step) of heating a board and soldering components to the board, and that an inspection device is installed and inspected after each step (for example, Patent Document 1).

In the above example of the production line for component-mounted boards, the inspection performed after the reflow process is an inspection for making the final pass/fail judgment of the product (hereinafter also referred to as final inspection). Inspections carried out in each intermediate process before that (hereinafter also referred to as intermediate inspections) are generally carried out as part of process control. In other words, by discovering intermediate products (defective intermediate products) that do not meet the quality level determined by each intermediate process and preventing such defective intermediate products from flowing to subsequent processes, we aim to improve the production efficiency of the entire line. This includes checking to see if any abnormalities have occurred in the process where the defective intermediate product was discovered.

By the way, some of the inspection items performed by these inspection devices are common to a plurality of inspection processes. However, from the perspective of preventing the "final" product from being overlooked on a production line that has multiple inspection processes (inspection equipment), if a defect can be detected in any one of multiple inspection processes/inspection items, it will be possible to avoid oversight. It is possible to prevent this. That is, a defect that can be detected in a certain inspection process (inspection item) does not necessarily need to be detected in another inspection process (inspection item).

In addition, for components mounted on the board to be inspected, even if the components are of the same type, the inspection equipment in charge of inspection and inspection parameters may be changed depending on the direction of mounting or the relationship with surrounding components. In some cases, it may not be possible to perform an inspection with sufficient accuracy unless multiple inspection devices are used.

For this reason, in a production line having a plurality of inspection devices, it is conceivable to perform inspections efficiently by coordinating the inspections in each inspection device and sharing the inspection items for detecting defects.

Japanese Patent Application Publication No. 2021-189791

By the way, in a manufacturing facility equipped with a plurality of production lines, inspection devices are not necessarily installed in the same combination on all production lines. Due to economic and spatial constraints, operating rates, product delivery dates, and other circumstances, even if the same product is being manufactured, the inspection equipment installed on the production line may be different. For example, there may be a coexistence of a production line in which only a single inspection device is installed at the end of every manufacturing process, and a production line in which an inspection device is installed for each manufacturing process.

For this reason, even if you have set up an inspection program that coordinates multiple inspection devices to perform inspections to detect product defects, in reality, the inspection program may not be able to detect defects in the inspection device. There is a risk that the product will be manufactured by a combination of production lines. In such a case, the inspection program applied to each inspection device assumes a combination of inspection devices that is different from the original combination of inspection devices, so the inspection items (and inspection parameters) performed by the target inspection device are ) may be inappropriate, and there is a risk that defects may be overlooked (overlooked).

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to provide a technology for each inspection device to carry out an inspection using an appropriate inspection program in a component mounting board production line having a plurality of inspection devices. Our goal is to provide the following.

In order to achieve the above object, the present invention employs the following configuration. That is,
An inspection management system that manages the inspection contents of one or more inspection devices installed in a production line for component mounting boards,
For each component mounted on the component mounting board, an inspection item that can detect defects in the component according to a combination of the inspection devices installed in the production line, and which inspection device performs the inspection related to the inspection item. Inspection program storage means for storing an inspection program that defines the content of inspection to be performed by each of the inspection devices on the component mounting board using inspection coverage information that determines whether the component mounting board is to be inspected;
Each of the inspection devices provided in the production line includes a first determining unit that determines which inspection coverage information is used to perform the inspection based on the inspection program.
This is an inspection management system characterized by:

Note that the terms first, second, third, etc. in this specification and claims are used to distinguish similar elements, and do not necessarily imply a sequential or chronological order. Do not mean. Furthermore, in this specification, the words "creation" and "setting" are used to include modification. In addition, in the above, "using inspection coverage information" includes the case where the inspection program itself owns the information or the inspection program refers to the information stored in another database. Furthermore, hereinafter, a combination of one or more inspection devices provided on a production line is also referred to as an "inspection configuration."

According to the system having such a configuration, when applying an inspection program to each inspection device provided on a production line, it is possible to apply an inspection program suitable for the inspection configuration of the production line to which the inspection device belongs.

Further, the inspection management system further includes an inspection coverage storage unit that stores one or more pieces of the inspection coverage information for each part number of the component, and the inspection program is configured to store the inspection coverage information stored in the inspection coverage storage unit. The contents of the inspection to be performed by each of the inspection apparatuses on the component mounting board may be determined by referring to the coverage information. With such a configuration, there is no need to prepare a large number of inspection program bodies for one component mounting board to be inspected. In other words, if you prepare one inspection program, by referring to the inspection coverage information according to the line configuration of the inspection equipment to which the inspection program is applied, you can check the inspection items (inspection parameters) according to the line configuration to which the inspection equipment belongs. Inspections can be carried out by

Further, the first determining means stores a first inspection program using the inspection coverage information that matches a combination of the inspection devices of the production line to which the inspection device to be determined belongs in the inspection program storage means. If stored, it may be determined to perform the test based on the first test program. With such a configuration, if an inspection program that matches the inspection configuration of the production line to which the inspection device belongs is prepared, the matching inspection program can be reliably applied to each inspection device.

Further, the first determining means may perform the inspection based on the inspection program substituted for the first inspection program when the first inspection program is not stored in the inspection program storage means. may be determined. With such a configuration, even if an inspection program that matches the inspection configuration of the production line to which the inspection device belongs is not prepared, it is possible to perform inspection on the production line.

Further, the first determining means stores in the inspection program storage means a second inspection program that uses the inspection coverage information such that the inspection of the component is completed only by the inspection device that is the target of the determination. If so, it may be determined to perform the test based on the second test program.

With such a configuration, even if an inspection program that matches the inspection configuration of the production line to which the inspection device belongs is not prepared, a program configured to complete the inspection on each inspection device is applied. be able to. For this reason, it is possible to prevent oversights at least in each inspection device.

Further, the first determining means includes:
In the case where the second inspection program is not stored in the inspection program storage means, the third inspection program using the inspection coverage information including the first inspection item that can be performed by the inspection apparatus that is the target of the determination is If it is stored in the inspection program storage means,
It is determined whether or not the first inspection item can be completed only by the inspection device that is the target of the determination, and if the result of the determination is true, the test is performed based on the third inspection program. It may also be a decision to perform a test for the first test item.

With such a configuration, even if the target inspection equipment cannot complete the quality determination of parts by itself, at least the inspection for defects that can be detected by the inspection items that can be performed by the inspection equipment concerned can be performed. An inspection program that allows for this can be applied.

Further, the first determining means may select the inspection item for detecting one or more of the defects and the inspection for performing the inspection related to the inspection item by any of the inspection programs stored in the inspection program storage means. If the device cannot be determined, it may be decided to perform at least a visual inspection for the defect. In other words, if there is even one defect that cannot be detected using the inspection program stored in the inspection program storage means (combined with the inspection equipment of the target production line), the defect will not be visually inspected. decide. With such a configuration, even if there is no appropriate inspection program for the inspection configuration and defects cannot be detected properly by inspection using each inspection device, visual inspection can prevent defective products from being overlooked. can.

Further, in the inspection management system, each of the inspection devices provided on the production line may include the inspection program storage means and the first determination means. Naturally, it is also possible to store an inspection program in a data server or the like and distribute an appropriate inspection program to each inspection device provided on the production line as the production line is operating. However, with the above configuration, even if communication with a data server or the like is interrupted for some reason, it is possible to select and apply an appropriate inspection program in each inspection device.

Further, each of the inspection devices provided in the production line is provided with a second deciding means for deciding whether or not to actually carry out the inspection determined by the first deciding means when carrying out the inspection. There may be. With this configuration, after the inspection program to be applied to each inspection device has been determined, it will be possible to avoid the situation in the event that it becomes inappropriate to carry out the inspection using the inspection program for some reason before the actual inspection is carried out. Even if the test program is no longer appropriate, it is possible to prevent the test from being performed using the test program that is no longer appropriate.

Further, each of the inspection devices installed in the production line is provided with pre-process inspection information that is information including whether or not a pre-process inspection has been performed on a predetermined inspection target related to the component mounting board at the time of carrying out the inspection. further comprising a pre-process inspection information acquisition means for acquiring the
The second determining means is configured to determine, in the pre-process inspection information, that an inspection has been performed in the pre-process when the inspection apparatus equipped with the second determining means is not installed in the earliest inspection process. The test may be determined to actually perform the test determined by the first determining means, on the condition that the information includes the following information.

With this kind of configuration, the pre-set division (cooperation) between the inspection devices can function properly because the inspection is carried out using the applied inspection program on the premise that the inspection in the previous process has been carried out. can be done.

Further, if the pre-process inspection information acquisition means cannot obtain the pre-process inspection information or obtains the pre-process inspection information indicating that there is no inspection in the pre-process, the second determination The means may cancel implementation of the test determined by the first determining means, and may also decide to implement measures to replace the test.

If there is a pre-process, and if there are no test results for the pre-process, or if it is unclear whether or not the pre-process has been tested, the premise of the division of tests between inspection devices will collapse. That is, the premise that the inspection program applied before the inspection is appropriate breaks down, so if the inspection is carried out with the same inspection program, there is a risk that defects will eventually be overlooked. In this regard, with the above configuration, it is possible to take measures to prevent failures from being overlooked, assuming that the inspection division between the devices has stopped functioning.

Further, in the case where the second determining means stores in the inspection program storage means a fourth inspection program that uses the inspection coverage information of which the inspection is completed only by the inspection apparatus including the second determining means. The measure may include determining implementation of the test based on the test content information referred to by the fourth test program.

With such a configuration, an inspection can be performed by applying a program that is set so that the inspection can be completed in the target inspection apparatus itself. For this reason, it is possible to prevent oversights at least in each inspection device.

Further, the second determining means may decide to carry out a visual inspection of the component as the measure when the fourth inspection program is not stored in the inspection program storage means. According to this configuration, even if there is no inspection program that can complete the inspection in the target inspection equipment itself, and there is a risk that defects cannot be detected properly, it is possible to overlook defective products by conducting a visual inspection. can be prevented.

The present invention also provides a method for determining the content of inspection to be performed by each of the inspection devices in an inspection management system that manages the inspection contents of one or more inspection devices installed in a production line for component mounting boards, comprising:
The inspection management system includes, for each component mounted on the component mounting board, inspection items that can detect defects in the component according to a combination of the inspection devices installed in the production line, and which inspection device is capable of detecting defects in the component. and an inspection program storage means for storing an inspection program that defines the content of the inspection to be performed by each of the inspection devices on the component mounting board using inspection coverage information that determines whether to perform the inspection related to the item. Ori,

Embodiments of the present invention will be described below based on the drawings. However, unless otherwise specified, the dimensions, materials, shapes, relative positions, etc. of the components described in the following examples are not intended to limit the scope of the present invention.

<Application example>
The present invention can be applied, for example, as an inspection management system 1 as shown in FIG. FIG. 1 is a schematic diagram showing an outline of a printed circuit board component mounting line (hereinafter also referred to as a production line) to which an inspection management system 1 according to this application example is applied. The component mounting line mainly consists of three processes: solder printing, component mounting, and reflow (solder welding).As shown in Figure 1, the component mounting line according to this application example is A solder printing device X1, a mounter X2, and a reflow oven X3 are provided in this order from the side.

In addition, the component mounting line is equipped with inspection equipment that inspects the condition of the board at the exit (and entrance) of each process of solder printing, component mounting, and reflow, and automatically detects defects or potential defects. . In the example of FIG. 1, the configuration includes a solder print inspection device Y1, a post-mount inspection device Y2, an appearance inspection device Y3, and an X-ray inspection device Y4. In the following, the inspection by the solder printing inspection device Y1 may be referred to as a post-print inspection, the inspection by the post-mount inspection device Y2 may be referred to as a post-mount inspection, the inspection by the visual inspection device Y3 and the X-ray inspection device Y4 may be referred to as a post-reflow inspection, etc. be.

The test management system 1 according to this application example includes a test management device 10 and a data server 20 in addition to the test devices Y1, Y2, Y3, and Y4 described above. Each of these configurations and each manufacturing device (X1, X2, X3) described above is connected to a LAN (Local A
rea Network).

Here, in the example of FIG. 1, the configuration includes a solder print inspection device Y1, a post-mount inspection device Y2, an appearance inspection device Y3, and an X-ray inspection device Y4, but for example, a manufacturing facility with multiple production lines , not all production lines are equipped with the same combination of inspection devices. Due to economic and space constraints, operating rates, product delivery dates, and other circumstances, even if the production line is equipped with the same manufacturing equipment (solder printing device x1, mounter x2, reflow oven x3), It is also conceivable that the (combination of) inspection devices used are different.

The inspection management system 1 according to this application example is not premised on including all inspection devices such as the solder print inspection device Y1, the post-mount inspection device Y2, the visual inspection device Y3, and the X-ray inspection device Y4. Further, the inclusion of other inspection devices in addition to these is not excluded. That is, the inspection management system 1 according to this application example includes one or more inspection devices provided in a component mounting line for component mounting boards, an inspection management device 10, and a data server 20.

The inspection management device 10 is a terminal responsible for managing and controlling manufacturing equipment, inspection equipment, etc., and although not shown, it includes a main storage device such as a CPU (Central Processing Unit), a RAM (Random Access Memory), and an auxiliary storage device (HDD). , flash memory, etc.), input devices (keyboard, mouse, controller, touch panel, etc.), output devices (displays, printers, speakers, etc.), communication means (wired or wireless), etc. configured. Each functional unit of the test management device 10, which will be described later, may be realized by the CPU reading and executing a program stored in an auxiliary storage device.

The test management device 10 can also be used as a so-called teaching terminal, and can create (including changes to, the same applies hereinafter) test programs that define the content of tests to be performed by each test device. In addition to this, it is also used for tasks such as registration and setting (including changes; the same applies hereinafter) of various information stored in the data server 20.

FIG. 2 shows a functional block diagram of the test management device 10 and data server 20 according to this application example. As shown in FIG. 2, the data server 20 includes a component inspection constraint design storage section 211, an inspection coverage information storage section 212, a product number group storage section 213, an inspection program storage section 214, and an inspection history information storage section 215. Ru.

Although the details of the data server 20 will be described later, the inspection coverage information storage unit 212 stores the inspection coverage information storage unit 212 for each component number of the component mounted on the component mounting board to be inspected, and for each combination of inspection equipment installed on the production line. It stores one or more sets of inspection coverage information, which is information that determines inspection items that can detect defects in target parts and which inspection apparatus will perform inspections related to the inspection items. In addition, the inspection program storage unit 214 stores an inspection program that determines the content of inspection to be performed by each inspection apparatus on the component mounting board by referring to the inspection coverage information.

Regarding inspection items for detecting defects in each component, the types of inspections (inspection items) that can be performed differ depending on the inspection apparatus. Further, in some cases, a plurality of different inspection devices can each perform an inspection (inspection item) that can detect a certain defect. For this reason, in the inspection management system according to this application example, inspection coverage information that indicates which inspection items are to be performed by which inspection equipment for each part number is determined and stored in advance. By referring to the inspection coverage information when creating an inspection program (described later), it is possible to create an inspection program that prevents defects from being overlooked and prevents duplicate inspections from being performed between inspection devices. Become.

Note that various combinations of inspection devices arranged on the production line are assumed, and combinations of inspection items are set accordingly. For example, a visual inspection device and an X-ray inspection may be used for the post-reflow inspection, or a line configuration may be envisaged in which no post-solder printing inspection is performed. Also, depending on the characteristics and arrangement of the components to be mounted, it may not be possible to properly inspect defects using a specific inspection device or inspection item (for example, for components with highly reflective surfaces, component height may be an inspection item). (for example, it is not appropriate to do so). In this way, it is desirable to define multiple variations of the inspection items and combinations of inspection devices necessary to inspect defects that should be detected for each part number, depending on the combination of various inspection devices and the characteristics of the parts. .

Therefore, the inspection coverage information storage unit 212 according to this application example includes inspection coverage information (first variation) that defines the combination of standard inspection items and inspection devices, as well as inspection items and inspection devices that are different from this. If there are combinations (other variations), inspection coverage information for these different variations is also stored.

Here, Figure 3 shows the variations of inspection coverage information set according to the assumed combination of inspection equipment arranged on the production line, and the inspection contents defined in the inspection program that refers to the inspection coverage information for each variation. An explanatory diagram showing an example of a relationship is shown. Note that in this specification and each drawing, the post-solder printing inspection is also expressed as P, the post-mounting inspection as Z, the post-reflow appearance inspection device as S, the post-reflow X-ray inspection as X, etc.

As shown in FIG. 3, various combinations of inspection devices arranged on a production line are assumed, and inspection variations are set accordingly. Specifically, there is a variation in which only the visual inspection device Y3 is installed and inspects all the defects that should be detected only by the post-reflow visual inspection, while the solder printing inspection device Y1, the post-mounting inspection device Y2, the visual inspection device Y3, There is also a variation in which all the inspection devices of the X-ray inspection device Y4 are provided and the inspection of defects to be detected is shared in the ZSX inspection process.

Then, an inspection program that defines inspection items to be performed by each inspection apparatus and inspection parameters for the inspection items is created according to these variations, and is stored in the inspection program storage unit 214.

Further, as shown in FIG. 2, the test management device 10 has a control section 110, an input section 120, and an image display section 130, and the control section 110 further includes a data reading section 111 and a UI control section as functional modules. 112, an inspection content setting section 113, a simulation execution section 114, an inspection coverage determination section 115, and an application program determination section 116.

Although the details of the inspection management device 10 will be described later, the applicable program determining unit 116 in the control unit 110 determines which inspection target ( (parts) to be inspected.

Here, application of the inspection program to each inspection apparatus determined by the application program determination unit 116 will be explained. FIG. 4A is a diagram showing an inspection configuration when one each of a solder print inspection device Y1, a post-mount inspection device Y2, an appearance inspection device Y3, and an X-ray inspection device Y4 are provided in a production line according to this application example. . FIG. 4B shows the contents of the inspection performed by each inspection device when an inspection program that refers to the inspection coverage information of a variation that matches the inspection configuration of FIG. 4A is applied to each inspection device regarding the inspection of the component number A. It is an explanatory view showing simply. That is, the table shown in FIG. 4B indicates that the application program determining unit 116 applies the inspection program that refers to the inspection coverage information related to the variation of "for PZSX line (ZSX inspection assignment)" in FIG. 3 to each inspection device. The division of inspections is shown in the table below.

Here, in the right column of FIG. 3, "S inspection" etc. refers to the post-reflow visual inspection, that is, the inspection program that defines the inspection contents (inspection items, inspection parameters) to be performed by the visual inspection device Y3. It shows. Furthermore, the word "single" in parentheses indicates that all defects to be detected are inspected only by the inspection device (inspection process). In addition, "XX sharing" in parentheses indicates that the inspection items and inspection parameters are set on the premise that the inspection will be shared with the inspection equipment corresponding to XX.

Next, a description will be given based on FIGS. 5A and 5B. FIG. 5A shows an example of a combination of inspection devices different from the case of FIG. 4A in the production line according to this application example, and has an inspection configuration in which the visual inspection device Y3 is not present. In such a case, the applied program determining unit 116 applies to each inspection apparatus an inspection program that refers to the inspection coverage information related to the variation "for PZX line (ZS inspection assignment)" in FIG. 3. The table in FIG. 5B shows the inspection assignment when applied in this manner. As shown in FIG. 5B, since the inspection device that performs the inspection in the S process is not included, in FIG. An inspection program performed by device Y4 is applied.

In addition, until now, even if the inspection configuration includes all PZSXs as shown in FIG. 4A, or the inspection process consists of PZXs as shown in FIG. 5A, inspection coverage information according to each inspection configuration has been The explanation has been made on the assumption that the information is stored in the inspection coverage information storage unit 212. However, the explanatory diagram shown in Figure 3 shows an example in which inspection coverage information is set (stored) according to various inspection configurations for the purpose of explanation only, and in reality, all possible inspections are set (stored). Inspection coverage information that covers all configurations is not necessarily set.

Next, based on FIGS. 6A and 6B, a case will be described in which there is no (variation of) inspection coverage information that matches the inspection configuration of the production line. Similar to the case shown in FIG. 5A, FIG. 6A shows a production line with an inspection configuration in which the visual inspection device Y3 is not present. In the cases shown in FIGS. 6A and 6B, the inspection coverage information storage unit 212 does not store the inspection coverage information of the variation that matches the inspection configuration, but the inspection coverage information of the variation that corresponds to the inspection configuration of PZSX. It is assumed that only the In such a case, the applied program determining unit 116 refers to the inspection coverage information of the variation corresponding to the PZSX inspection configuration for the solder print inspection device Y1 and the post-mount inspection device Y2, as shown in FIG. 6B. Decide to apply an inspection program. In addition, for some inspection items (inspection items that detect void defects) that can be completed by the X-ray inspection device only with the X-ray inspection device Y4, refer to the inspection coverage information of the variation corresponding to the inspection configuration of PZSX. Apply the inspection program. Visual inspection will be conducted for "wetting defects" which are to be detected in the S inspection process and "bonding defects" which are to be detected by combining the S and X inspections. decide. Here, the visual inspection may be carried out in any manner; for example, the component mounting board may be passed through a visual inspection device (not shown) provided after the X-inspection after reflow.

According to the inspection management system 1 according to the present application example as described above, if each production line has an appropriate inspection program according to the inspection configuration of the line, each inspection device installed on the line An optimal inspection program can be applied depending on the inspection configuration. On the other hand, even if there is no inspection program suitable for the inspection configuration, if there is inspection coverage information that includes inspection items that can be performed by each inspection device, an inspection program that refers to the inspection coverage information is applied. This makes it possible to perform inspections on inspection items that can be carried out by each inspection device, and to cover defects that cannot be detected or properly inspected by any inspection device through visual inspection. .

<Embodiment 1>
Next, the inspection management system 1, which is an example of a mode for carrying out the present invention, will be described in more detail below.

(Details of each inspection device)
Returning to FIG. 1, details of each of the inspection devices Y1, Y2, Y3, and Y4 included in the component mounting line of the inspection management system 1 according to the present embodiment will be explained. In addition to automatically sorting into good and defective products, each inspection device also has a function of feeding back the inspection results and analysis results to the operations of each manufacturing device.

The solder printing inspection device Y1 is a device for inspecting the printed state of solder paste on a board taken out from the solder printing device X1. The solder print inspection device Y1 measures the solder paste printed on the board two-dimensionally or three-dimensionally, and based on the measurement results, determines whether or not various inspection items have normal values (tolerable ranges). Inspection items include, for example, the volume, area, height, positional shift, and shape of the solder. For two-dimensional measurement of solder paste, an image sensor (camera), etc. can be used, and for three-dimensional measurement, a laser displacement meter, phase shift method, spatial coding method, optical cutting method, etc. can be used. can.

The post-mount inspection device Y2 is a device for inspecting the placement state of electronic components on the board taken out from the mounter X2. The post-mount inspection device Y2 measures the component placed on the solder paste in two or three dimensions (the component body, electrodes, or other part of the component), and uses the measurement results to determine various inspection items. Determine whether the value is normal (tolerable range). Inspection items include, for example, misalignment of parts, misalignment of angle (rotation), missing parts (components are not placed), wrong parts (different parts are placed), and wrong polarity (between the part side and the board). (the polarity of the side electrodes is different), front-back reversal (the parts are placed face down), and the height of the parts. Similar to solder print inspection, image sensors (cameras) can be used for two-dimensional measurement of electronic components, while laser displacement meters, phase shift methods, spatial coding methods, and optical cutting methods can be used for three-dimensional measurements. etc. can be used.

The appearance inspection device Y3 is a device for inspecting the quality of soldering on the board taken out from the reflow oven X3. The appearance inspection device Y3 measures the solder portion after reflow two-dimensionally or three-dimensionally, and determines whether or not various inspection items have normal values (tolerable ranges) based on the measurement results. In addition to the same items as component inspection, the inspection items also include the quality of the solder fillet shape. In addition to the laser displacement meter, phase shift method, spatial coding method, and optical cutting method mentioned above, the so-called color highlight method (R, G, and B illumination is applied to the solder surface at different incident angles) is used to measure the shape of solder. The three-dimensional shape of the solder can be detected as two-dimensional hue information by capturing the reflected light of each color with a zenith camera.

The X-ray inspection device Y4 is a device for inspecting the soldering state of a board using an X-ray image. For example, in the case of package parts such as BGA (Ball Grid Array) and CSP (Chip Size Package), and multilayer boards, the solder joints are hidden under the parts and boards, so the visual inspection equipment Y3 (in other words, the external appearance image) cannot inspect the condition of the solder. The X-ray inspection device Y4 is a device to compensate for such weaknesses in visual inspection. Inspection items of the X-ray inspection device Y4 include, for example, misalignment of components, solder height, solder volume, solder ball diameter, back fillet length, and quality of solder joints. Note that as the X-ray image, an X-ray transmission image or a CT (Computed Tomography) image may be used. In the following description, the visual inspection device Y3 and the X-ray inspection device Y4 may be collectively referred to as a post-reflow inspection device.

Further, each of the inspection devices Y1, Y2, Y3, and Y4 according to the present embodiment may be provided with a display device for visually confirming the inspection object, and the visual display device is different from each inspection device. It may be provided as a separate terminal (that is, as a visual inspection device) in the component mounting line.

(Inspection management device)
On the other hand, the test management device 10 of the test management system 1 according to the present embodiment may be configured by one computer or may be configured by a plurality of computers. Alternatively, it is also possible to implement all or part of the functions of the inspection management device 10 in a computer built in any one of the manufacturing devices X1, X2, and X3 and the inspection devices Y1, Y2, Y3, and Y4. Alternatively, some of the functions of the test management device 10 may be realized by a server on a network (such as a cloud server).

(data server)
The data server 20 is a terminal having a large storage capacity, and stores various data in addition to the above-mentioned inspection coverage information and inspection programs. It transmits information held to the inspection management device 10, manufacturing devices X1, X2, and X3, and inspection devices Y1, Y2, Y3, and Y4, and conversely receives information from these devices.

(Functional block)
Referring again to FIG. 2, functional blocks related to the test management device 10 and data server 20 of this embodiment will be described. As shown in FIG. 2, the data server 20 includes a component inspection constraint design storage section 211, an inspection coverage information storage section 212, a product number group storage section 213, an inspection program storage section 214, and an inspection history information storage section 215. Ru.

The component inspection constraint design storage unit 211 is a database that stores component inspection constraint design information that defines one or more types of defects to be detected for each type of component mounted on a component mounting board.

As described above, the inspection coverage information storage unit 212 stores a combination of inspection items that can detect each defect in the component inspection constraint design information according to the combination of inspection devices provided on the component mounting line for each part number of the component. This is a database that stores one or more sets of defined inspection coverage information.

The product number group storage unit 213 stores product number group information in which a plurality of component product numbers to which inspection coverage information of the same content is applied are grouped. Inspection coverage information may be set and changed on a product number group basis.

In addition, the inspection program storage unit 214 is a database that stores an inspection program that determines the content of the inspection that each inspection apparatus performs on the component mounting board using the above-mentioned inspection coverage information. In addition, the inspection history information storage unit 215 stores inspection history information related to the results of inspections (image data, three-dimensional shape data, final pass/fail judgment results, etc.) conducted in each of the inspection apparatuses Y1, Y2, Y3, and Y4 in the past. This is a database that stores information.

In this embodiment, a component inspection constraint design storage section 211 , an inspection coverage information storage section 212 , a product number group storage section 213 , an inspection program storage section 214 , an inspection history information storage section 21
5 functions as a so-called relational database in which stored information can be referred to and interlocked with each other. That is, the inspection program described below does not hold information on defect types related to the component inspection constraint design information and information on inspection items (and their inspection parameters) related to the inspection coverage information, but instead stores the component inspection constraint design storage unit 211, By referring to information stored in the inspection coverage information storage unit 212, the content of the inspection to be performed by each inspection device may be defined.

Further, as described above, the test management device 10 includes a control section 110, an input section 120, and an image display section 130, and the control section 110 further includes a data reading section 111, a UI control section 112, and a UI control section 112 as functional modules. It includes an inspection content setting section 113, a simulation execution section 114, an inspection coverage determination section 115, and an application program determination section 116.

The input unit 120 is an input means to the test management apparatus 10, and is typically configured with a keyboard, a mouse, a controller, a touch panel, etc. The image display unit 130 is a means for outputting user interface images such as an inspection coverage setting confirmation image to be described later, and other various information, and is typically configured by a display device such as a liquid crystal display.

Next, each functional module included in the control unit 110 will be explained. The data reading unit 111 reads out various information related to inspection program confirmation/setting processing from the data server 20, and supplies the information to the UI control unit 112, inspection content setting unit 113, simulation execution unit 114, inspection coverage determination unit 115, and application program. The information is provided to the determining unit 116.

The UI control unit 112 displays images related to inspection program confirmation and settings on the image display unit 130, receives user operations, and executes processing in accordance with the operations in cooperation with the inspection content setting unit 113. That is, the image created by the UI control unit 112 and displayed on the image display unit 130 includes a UI image that also serves as a user interface. FIG. 7 shows an inspection coverage setting confirmation image that is an example of such an image. As shown in FIG. 7, the inspection coverage setting confirmation image according to this embodiment shows which inspection equipment installed in the component mounting line detects each defect in the component inspection constraint design information, with one component part number as one unit. It displays a list of what to do. More specifically, one axis shows a list of defect types in the component inspection constraint design information, and the other axis includes a matrix list showing a list of each inspection device installed in the component mounting line. In the table, the name of the inspection item that detects a defect is displayed in the column where the row or column indicating the inspection device that detects the defect intersects with the row or column indicating the detected defect.

The inspection content setting unit 113 reads information necessary for checking and setting the inspection program (component inspection constraint design information, inspection coverage information, product number group information, etc.) from the data server 20 and provides it to the UI control unit 112. , create an inspection program (new settings, changes) based on information input by user operations. Specifically, through a user interface as shown in the inspection coverage setting confirmation image, the user is presented with component inspection constraint design information and inspection coverage information (including inspection items and inspection parameters), and each information An inspection program is created by accepting new inputs and changes.

In addition, the inspection content setting unit 113 may create (newly set or change) component inspection constraint design information, inspection coverage information, product number group information, etc. in the process of creating an inspection program. The created inspection program is stored in the inspection program storage section 214, component inspection constraint design information is stored in the component inspection constraint design storage section 211, inspection coverage information is stored in the inspection coverage information storage section 212, and product number group information is stored in the product number group storage section. 213, respectively.

The simulation execution unit 114 selects the currently set inspection contents (inspection (items and inspection parameters). Based on the results of the simulation, if the currently set inspection details result in defects being overlooked or overlooked, the information is provided to the UI control unit 112. The UI control unit 112, which has received the information, displays a notification on the inspection coverage setting confirmation image that the inspection coverage setting confirmation image will be overlooked or overlooked.

FIG. 8 shows an example of an inspection coverage setting confirmation image indicating that the current inspection content may cause oversight or over-sighting. As shown in FIG. 8, if a defect is overlooked or overlooked in the currently set inspection content, for example, the name of the inspection item that is missed or overlooked is highlighted so that it can be identified. The example in FIG. 8 shows that an oversight occurs when inspecting the inspection item "component difference (height)" in the post-mount inspection performed in the inspection device Y2, and "voids" in the X-ray inspection performed in the inspection device Y4. (Area)" indicates that over-examination occurs.

The inspection coverage determining unit 115 determines, for each component, whether the currently set inspection coverage includes inspection items for detecting all types of defects in the component inspection constraint design information. As a result of the determination, if an inspection item for detecting any of the defects is not set, information to that effect is provided to the UI control unit 112. Upon receiving the information, the UI control unit 112 displays an alert on the inspection coverage setting confirmation image that there is a defective type for which inspection items have not been set. In the present embodiment, the "!" mark displayed next to "Not wet" in the list of defective types in FIG. 8 corresponds to such an alert display.

As described above, the applied program determining unit 116 determines which inspection coverage information each of the inspection apparatuses provided on the production line refers to based on which inspection program the inspection target (part) is to be inspected. .

(Flow of inspection program application process)
Here, the flow of processing when the applicable program determining unit 116 determines an inspection program to be applied to each inspection apparatus will be explained based on FIGS. 9 and 10. FIGS. 9 and 10 are flowcharts showing the flow from when the application program determining unit 116 determines an inspection program to be applied to each inspection apparatus to when each inspection apparatus executes an inspection.

First, a process of identifying a substrate to be inspected is performed (step S101). This may be specified by the user via the input unit 120, or the applicable program determining unit 116 may specify the program from the component mounting line to which the inspection device targeted for the program application process belongs via the network. Information about the board may also be acquired. Next, the applied program determining unit 116 acquires information (inspection configuration information) regarding the combination of inspection devices installed in the target component mounting line (S102). This may be input by the user via the input unit 120, or may be obtained from the component mounting line via the network.

Then, the applied program determining unit 116 determines whether inspection coverage information that matches the acquired inspection configuration information is stored in the inspection coverage information storage unit 212 for each part number of the component to be mounted on the identified board. It is determined whether it is correct or not (S103). Here, if the determination result is "true", the application program determining unit 116 selects an inspection program (related to the inspection device targeted for the application process) that refers to the inspection coverage information that matches the acquired inspection configuration information. (S104). Then, a process of transmitting the inspection program from the inspection program storage unit 214 to the target inspection apparatus is performed. Thereafter, a process applied to the inspection is performed in the inspection apparatus that is the target of the application process (S105), and an inspection is performed based on this (S106), and the series of flows ends.

On the other hand, if it is determined that the inspection coverage information that matches the inspection configuration information acquired in step S103 is not stored in the inspection coverage information storage unit 212, the applied program determination unit 116 performs the inspection on the target inspection apparatus alone. It is determined whether inspection coverage information that is completed is stored (S111). That is, if the inspection device targeted for the inspection program application process is the visual inspection device Y3, inspection coverage information that allows inspection of all defects to be detected by S alone is stored in the inspection coverage information storage unit 212. Determine whether or not the Here, if the determination result is "true", the applied program determining unit 116 determines to apply the inspection program that refers to the inspection coverage information to the inspection performed by the target inspection apparatus (S112). Then, processing is performed to transmit the inspection program from the inspection program storage unit 214 to the target inspection apparatus. Thereafter, the program is applied to the target inspection device (S113), and an inspection is performed based on the program (S106). In such cases, the inspection is carried out with the inspection content that can be completed by the target inspection equipment alone, so for the entire production line, multiple inspections are performed with multiple inspection equipment to detect a certain defect. However, it is possible to prevent failures from being overlooked.

In addition, if it is determined in step S111 that no inspection coverage information is stored that allows the inspection to be completed by the target inspection device alone, the applicable program determining unit 116 performs an inspection including inspection items to be performed by the target inspection device A process is performed to determine whether coverage information is stored or not (S121). Here, if the determination result is "true", the applicable program determining unit 116 determines whether the inspection items to be performed by the target device included in the inspection coverage information are completed by the target inspection device alone. It is further determined whether or not it is an inspection item (S122). Here, if the determination result is "true", the application program determining unit 116 determines to apply the inspection program that refers to the inspection coverage information to the target inspection apparatus (S123). Then, processing is performed to transmit the inspection program from the inspection program storage unit 214 to the target inspection apparatus. After that, in the target inspection device, the inspection contents of the inspection items that can be completed by the own device, which are defined in the transmitted inspection program, are applied (S124), and the inspection is performed based on this. (S106). In such a case, it is possible to carry out inspections for inspection items that can be carried out by the target inspection equipment, even if inspection coverage information that matches the inspection configuration of the production line is not stored. By combining multiple inspection coverage information (multiple inspection programs that refer to it), each inspection device inspects the inspection items that it can perform, and the entire production line performs inspections that prevent defects from being overlooked. be able to.

On the other hand, in step S122, the inspection items performed by the target device are not inspection items that can be completed by the target inspection device alone (for example, the inspection items in multiple steps such as the inspection item for poor bonding in FIG. 4B etc.). If it is determined that the defect to be detected cannot be inspected by the inspection apparatus, the applicable program determination unit 116 determines to perform a visual inspection (S131). Further, even if it is determined in step S121 that the inspection coverage information including the inspection items to be performed by the target device is not stored, the applicable program determining unit 116 determines that the test by the target device is impossible. It is decided to perform a visual inspection (S131), and the series of routines ends.

In this way, the applicable program determining unit 116 can apply the inspection program that is capable of inspecting defects that should be detected by the target inspection device even when the inspection program cannot be applied (does not exist).
Since the implementation of the visual inspection is determined, it is possible to prevent an inspection from being performed using an inspection program that does not ensure comprehensiveness of inspection for defects.

According to the inspection management system 1 having the above-described configuration, when creating an inspection program for a component mounting line equipped with a plurality of inspection devices, a user can perform the following operations across the plurality of inspection devices for each component part number: In addition, it becomes possible to set the contents of the inspection to be performed by each inspection device, covering all types of defects to be detected. In addition, when applying the inspection program set in this way to each inspection device, it is determined which inspection coverage information to refer to or not depending on the inspection configuration of the production line to which the inspection device belongs. This process can be performed automatically. Additionally, since a decision is made to conduct a visual inspection if there is no appropriate inspection program, it is possible to prevent defective products from being overlooked due to inspection using an inspection program that does not ensure comprehensive inspection coverage for defects. can do.

(Modified example)
Note that in the test management system 1 according to the embodiment described above, the applicable program determining unit 116 is provided as a functional module of the test management device 10, but it does not necessarily have to have such a structure. FIG. 11 shows a schematic configuration of an inspection management system 2 according to such a modification. In addition, in this modification, the same components as those of the test management system 1 according to the first embodiment are given the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 11, the inspection management system 2 according to this modification differs from the inspection management system 1 in the solder print inspection device Y11, the post-mount inspection device Y12, the visual inspection device Y13, and the X-ray inspection device Y14. , the other points have the same configuration as the inspection management system 1. In the inspection management system 2 according to this modification, each of the inspection apparatuses Y11, Y12, Y13, and Y14 has an applied program determination section Y111, Y121, Y131, and Y141, and an inspection program storage section Y112, Y122, Y132, and Y142, respectively. It is configured to include a functional section.

In the test management system 1 according to the first embodiment, the applicable program determining unit 116 of the test management device 10 executes a process of determining a test program to be applied to each test device, and sends information from the data server 20 to each test device. The configuration was such that the determined inspection program was sent. On the other hand, in the inspection management system 2 according to this modification, at least the inspection program related to the own inspection process is stored in advance in the inspection program storage units Y112, Y122, Y132, and Y142 of each inspection device Y11, Y12, Y13, and Y14. The configuration is as follows.

Then, when the component mounting board to be manufactured on the production line is specified, the applicable program determination units Y111, Y121, Y131, and Y141 of each of the inspection devices Y11, Y12, Y13, and Y14 select the inspection program related to the inspection that they themselves carry out. Perform processing to determine. Note that the flow of processing performed in each of the application program determination units Y111, Y121, Y131, and Y141 is substantially the same as the flow related to FIGS. 9 and 10 performed by the application program determination unit 116 of the test management system 1. The difference from the inspection management system 1 is that after determining the inspection program to be applied in each inspection device, the inspection program is not received from the data server 20, but is stored in each inspection program storage unit Y112, Y122, Y132, Y142. The only point is to read and apply the inspection program that has been installed.

According to the inspection management system 2 according to the above-described modification, even if communication with a data server etc. is cut off for some reason, an appropriate inspection program can be selected and applied in each inspection device. becomes possible.

<Embodiment 2>
Next, other embodiments of the present invention will be described based on FIGS. 12 and 13. FIG. 12 is a diagram schematically showing the inspection management system 3 according to this embodiment and a component mounting line to which the inspection management system 3 is applied. Note that this embodiment has many configurations in common with Embodiment 1, and the same components as those of the test management system 1 according to Embodiment 1 are denoted by the same reference numerals and description thereof will be omitted.

As shown in FIG. 12, the inspection management system 3 according to the present embodiment is different from the inspection management system 1 in the solder print inspection device Y21, post-mount inspection device Y22, visual inspection device Y23, and X-ray inspection device Y24. , the other points have the same configuration as the inspection management system 1. In the inspection management system 3 according to the present embodiment, each of the inspection apparatuses Y21, Y22, Y23, and Y24 includes an execution program determining section Y211, Y221, Y231, and Y241, and a pre-process inspection information acquisition section Y212, Y222, Y232, and Y242, respectively. The configuration includes each functional section. In the following, for convenience of explanation, implementation program determination units Y211, Y221, Y231, Y241 and pre-process inspection information acquisition units Y212, Y222, Y232, Y242 will be explained separately when it is not necessary to explain them separately. The reference numerals are omitted, and they are simply referred to as "execution program determining section", "pre-process inspection information acquisition section", etc.

The implementation program determining unit determines whether or not to actually perform the inspection using the inspection program that the applicable program determining unit 116 has decided to apply when each of the inspection apparatuses Y21, Y22, Y23, and Y24 conducts an inspection. . In addition, the pre-process inspection information acquisition unit provides information including whether or not a pre-process inspection is performed on a predetermined inspection target related to a component mounting board when each inspection device Y21, Y22, Y23, and Y24 performs an inspection. Obtain pre-process inspection information. Here, the "predetermined inspection target related to a component-mounted board" may be the component-mounted board itself, a specific circuit on the board, or an individual component.

Here, in each of the inspection devices Y21, Y22, Y23, and Y24, after the inspection program to be applied is determined and before the actual inspection is performed, if for some reason it becomes inappropriate to carry out the inspection using the inspection program. can also be considered. Specifically, for example, if another inspection device that was supposed to share the inspection breaks down, or if the inspection is only carried out at a location different from the production line where the manufacturing device is located, It can be assumed that the inspection was not carried out in the previous process.

The implementation program determining unit has the role of preventing the test from being carried out as it is when the content of the test program that the application program determining unit 116 has decided to apply is no longer appropriate. fulfill. Specifically, based on the pre-process inspection information acquired by the pre-process inspection information acquisition unit, it is determined whether or not the inspection in the pre-process has been properly conducted for the inspection target, and the judgment result is "Accurate". Only in certain cases, an inspection is performed using the contents of the inspection program that the applicable program determining unit 116 has decided to apply.

Below, the flow of processing performed by the implementation program determination section will be explained based on FIG. 13. FIG. 13 is a flowchart showing an example of the flow of processing performed by the implementation program determining section. As shown in FIG. 13, the implementation program determining unit first obtains various types of information (S201). Here, the various information includes information related to the inspection configuration of the production line where the own device is installed, information on whether or not the inspection in the previous process was appropriately implemented, and information on the inspection that the application program determining unit 116 has decided to apply. Contains program information, etc.

Subsequently, based on the information acquired in step S201, it is determined whether the inspection process in which the own device is placed is the first inspection process (S202). Here, if the result of the determination is "true", the application program determining unit 116 performs the test using the contents of the test program that it has decided to apply (S203), and the series of routines ends. On the other hand, if it is determined in step S202 that the inspection process in which the own device is placed is not the first process, the process advances to step S204. In step S204, it is determined whether the inspection has been properly performed in the inspection device placed in the inspection process before the own device (S204). Specifically, if pre-process inspection information cannot be obtained, or if pre-process inspection information indicating that the pre-process inspection has not been carried out is obtained, it is assumed that the inspection is not being conducted properly. All you have to do is judge.

If it is determined in step S204 that the inspection was properly performed by the inspection device placed in the inspection process before the own device, the process proceeds to step S203, and the content of the inspection program that the applicable program determining unit 116 has decided to apply is An inspection is performed (S203), and the series of routines ends. On the other hand, if the determination result in step S204 is "No", the implementation program determining unit cancels the inspection using the inspection program that the applicable program determining unit 116 has decided to apply to the inspection target, and performs a visual inspection. is determined (S205), and the series of routines ends.

According to the configuration that performs such processing, even if an inspection is performed using the inspection program that the applicable program determining unit 116 has decided to apply due to some circumstances (for example, a failure of another inspection device or human error), the application may no longer be appropriate. If a situation arises in which it is not possible to perform an inspection that can detect defects, it is possible to prevent such an inspection from being conducted with inappropriate content.

(Modified example)
Note that the implementation program determining unit may perform the following process separately from the process shown in FIG. 13 described above. FIG. 14 shows an example of such other processing. As shown in FIG. 14, steps S201 to S204 are the same as the above-mentioned processing, so the description thereof will be omitted. In this modification, the process is different from that described above when it is determined in step S204 that the inspection is not properly performed by the inspection device placed in the inspection process before the own device.

In this modification, when the determination result in step S204 is "no", the implementation program determining unit performs an inspection that refers to inspection coverage information that allows the inspection of the inspection target (component) to be completed only by the own device. A process of determining the presence or absence of a program is performed (S301). Specifically, the determination may be made by communicating with the inspection coverage information storage section 212, inspection program storage section 214, etc., and confirming whether information is stored therein. Here, if there is an inspection program that refers to inspection coverage information whose inspection can be completed only by the own device, the execution program determining unit determines to carry out inspection with the contents of the inspection program (S302). More specifically, the execution program determination unit reads out the inspection program and applies it to its own device, performs an inspection in which defect detection can be completed only by its own device, and ends the series of routines.

On the other hand, if it is determined in step S301 that there is no inspection program that refers to inspection coverage information that can be inspected only by the own device, a decision is made to perform a visual inspection (S303), and a series of routine routines are performed. end.

With a configuration that performs such processing, even if for some reason it becomes inappropriate to perform an inspection using the contents of the inspection program that the applicable program determining unit 116 has decided to apply, each inspection device can independently perform the inspection. If there is an inspection program that completes the inspection of the defective object to be inspected, it becomes possible to perform the inspection by applying the inspection program. This eliminates the need to perform a visual inspection by uniformly determining that inspection is not possible, thereby increasing the efficiency of inspection and reducing the burden on the user. In addition, in both the case of the said Embodiment 2 and the case of this modification, a series of routines may be repeatedly performed for each arbitrary inspection object (component, circuit, board|substrate).

<Others>
The above description of the embodiments is merely for illustratively explaining the present invention, and the present invention is not limited to the above-described specific forms. The present invention can be modified in various ways within the scope of its technical idea. For example, it is also possible to realize an inspection management system that combines the configuration of the modified example of the first embodiment (a configuration in which each inspection device includes the applied program determination unit 116) and the configuration of the second embodiment.

Furthermore, in each of the above embodiments, the inspection program refers to the inspection coverage information (and component inspection constraint design information) to determine the inspection content that each inspection device installed on the production line performs on the inspection target. However, it is not necessarily limited to this. For example, the inspection program itself may have necessary information such as inspection coverage information.

In addition, in each of the above examples, component inspection constraint design information is set for each component type, but component inspection constraint design information is further determined for each electrode type that the component of the component type has, and component inspection constraint design information is set for each type of component. It may be stored in the storage unit. In addition to defects affecting the entire part (wrong part, missing part, upside down, part misalignment, etc.), there are also defects targeting the electrodes of the part (electrode floating, electrode displacement, non-wetting, etc.). If the configuration is correct, more appropriate tests can be set.
