Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In the description of the drawings below, the same or similar reference numerals are given to the same or similar parts. However, the drawings are schematic and illustrate an apparatus and a method for embodying the technical idea of the present invention in which the material, shape, configuration, arrangement, and the like of the structural elements are not specific to the following. The technical idea of the present invention can be modified in various ways within the technical scope defined by the claims described in the claims.
Fig. 1 is a schematic configuration diagram showing an example of a substrate information providing system to which the present invention is applied. The substrate information providing system 1 does not mark on the printed circuit board a rectangular or circular pattern or arrow indicating the position, size, polarity direction, etc. of the mounted electronic component, which is normally marked on the printed wiring board, and a symbol mark indicating the model, manufacturer, specification, etc. of the electronic component, but virtually superimposes and displays these symbol marks on the printed circuit board.
As shown in fig. 1, the substrate information providing system 1 includes: the server apparatus 2, the database (storage unit) 3, the administrator terminal 4 for the system administrator, and the user terminal 5, and the administrator terminal 4 and the user terminal 5 communicate with the server apparatus 2 via a communication line 6 such as the internet.
The administrator terminal 4 is configured by a personal computer or the like connectable to the internet, and includes: an input unit for inputting a request or the like, a display unit for displaying notified information, and a processing unit for notifying the server device 2 of the request or the like input by the input unit and displaying a response corresponding to the request or the like notified from the server device 2 on the display unit.
The user terminal 5 is configured by a smartphone, a personal computer, or the like that can be connected to the internet, and includes: an input unit 5a for inputting a request through a touch panel, an operation button, or the like, a display unit 5b for displaying notified information, and a processing unit for notifying the server device 2 of the request or the like input by the input unit and displaying a response corresponding to the request or the like notified from the server device 2 on the display unit 5 b.
The server device 2 is constituted by a computer or the like and includes the following processing units: the request notified from the administrator terminal 4 or the user terminal 5 is output, then the database 3 is registered according to the content of the request, and necessary information is read out from the database 3 and a response corresponding to the request is notified to the terminal of the request source.
The database 3 stores customer information, board information related to printed boards provided to customers, charge information for performing charge management necessary for managing the board information provided to customers, and the like.
The customer information is associated with, for example, a customer name, an ID number given to the customer, and a password set by the customer.
The substrate information is associated with, for example, a customer name, an identification code for identifying the type of printed wiring substrate sold to the customer, and data relating to the printed wiring substrate identified by the identification code. Examples of the Data relating to the printed wiring board include Design Data, CAD (Computer-Aided Design) Data, manufacturing history Data, inspection history Data, MSDS (Material Safety Data Sheet) Data, SPEC (specification of product), pattern Data, and solder resist Data. The data related to the printed wiring board includes symbol image data. The symbol image data (image information) is data for displaying a printed wiring board as follows: a rectangular or circular pattern and an arrow indicating the position, size, polarity direction, and the like of the mounted electronic component, and a symbol mark indicating the model, manufacturer, specification, and the like of the electronic component, which are indicated on a normal printed wiring board, are indicated. The symbol image data can be formed by selecting from three types, for example. The first type is image data (actual image information) for displaying an actual image obtained by imaging a printed wiring board on which symbol marks are marked, as shown in fig. 2 (a). The second type is image data (partial virtual image information) for displaying an image in which virtual symbol marks generated from CAD data are superimposed on an actual image obtained by imaging a printed wiring board on which symbol marks are not marked, as shown in fig. 2 (b). In fig. 2 (b), a virtual symbol mark is shown, and a dotted line shows an actual image. The third type is image data (full dummy image information) for displaying a dummy image of the printed wiring board generated from CAD data and having symbol data marked thereon, as shown in fig. 2 (c).
The user specifies any one of the three types of images to display the printed wiring board with the symbol marks indicated thereon in any one of the display modes (a) to (c) of fig. 2.
Next, an example of a processing procedure when the user registers an ID in the substrate information providing system 1 will be described.
When a user operates the user terminal 5 to make an ID registration request and input audit information, the audit information is output to the administrator terminal 4 via the server device 2, and the system administrator determines whether or not to permit the user making the ID registration request as a service user who provides the baseboard information based on the audit information. When it is determined that the service user is permitted, the server device 2 notifies the user terminal 5 of the ID, and the server device 2 stores the customer name in the database 3 in association with the password and the ID input from the user terminal 5. If the service user is not permitted, the registration with the database 3 is not performed.
Fig. 3 to 5 are flowcharts showing an example of a processing procedure when the user registers in the substrate information providing system 1, and show a processing procedure in the user terminal 5 (fig. 3), the server device 2 (fig. 4), and the administrator terminal 4 (fig. 5).
In order to acquire information on the printed wiring board from the board information providing system 1, the user first performs ID registration.
Specifically, as shown in fig. 3, in the user terminal 5, an ID registration request is made (step S1), then an input request of the audit information is made in accordance with the server apparatus 2 (step S2), and the specified audit information is input.
Next, the process proceeds to step S3, and if registration is enabled is notified from the server apparatus 2, the process proceeds to step S4, and the input password is output to the server apparatus 2 as a response corresponding to the request from the server apparatus 2. When the registration completion notification is input from the server device 2, the process at the time of ID registration is ended (step S5)
On the other hand, when the notification of the inability to register is made in accordance with the processing of step S3, the flow moves from step S3 to step S6, and the display section 5b displays that the registration is not enabled and ends the processing.
As shown in fig. 4, in the server apparatus 2, upon receiving an ID registration request from the user terminal 5 (step S11), an input request for review information for determining whether or not to register the user who made the registration request is transmitted to the user terminal 5, and the input review information is transmitted to the administrator terminal 4 as a response thereto.
Then, when the user terminal 5 receives the result of the examination and notifies that the registration is permitted, the process proceeds from step S13 to step S14, where the user terminal 5 is given an ID and a password input request is made. Next, when the password is input from the user terminal 5, the customer name of the user terminal 5, the ID assigned to the user terminal 5, and the input password are registered in the database 3 as customer information in association with each other, and a registration completion notification is notified to the user terminal 5 (step S15). The process then ends.
On the other hand, if the registration is not permitted in step S13, the process proceeds to step S16 and the display unit 5b notifies that registration is not possible. The process then ends.
Thereby, the customer name, ID, and password of the user terminal 5 that has made the ID registration request are newly registered in the database 3.
As shown in fig. 5, the administrator terminal 4 receives the ID registration request from the server device 2 (step S21), inputs the review information, reviews the customer who has made the ID registration request based on the review information, and outputs the result to the user terminal 5 (step S23).
Next, an example of a processing procedure when the user receives the substrate information from the substrate information providing system 1 will be described.
When a user requests the user terminal 5 to display symbol image data as substrate information and inputs an ID and a password, the server device 2 checks the customer name, ID, and password, and reads display information of a symbol mark corresponding to an identification code input from the user terminal 5 only when the client name, ID, and password match, and outputs the display information to the user terminal 5. The display information of the symbol mark is displayed on the display unit 5b in the user terminal 5.
Fig. 6 and 7 are flowcharts showing an example of a processing procedure when the user receives the symbol data serving as the substrate information from the substrate information providing system 1, and show an example of a processing procedure in the user terminal 5 (fig. 6) and the server device 2 (fig. 7).
When the user requests the display of the symbol image data as the substrate information in the user terminal 5, the server device 2 is notified of the request for the display of the symbol image data (step S31), and the server device 2 is notified of the ID and the password input by the user (step S32). When the server apparatus 2 is notified of the identification code input request (step S33), the identification code input by the user is output to the server apparatus 2 (step S34).
Here, the identification code input by the user may be manually input by the user at the user terminal 5, or may be read by using an OCR (Optical Character Recognition) technique such as reading by a digital camera or reading by a dedicated reader.
Next, the user terminal 5 inputs display information of the symbol image data as the substrate information corresponding to the identification code from the server device 2, and displays the display information on the display unit 5b of the user terminal 5 (step S35).
The user can easily recognize the circuit structure of the printed wiring board by referring to the image superimposed on the printed wiring board by the symbol mark shown in fig. 2 displayed on the display unit 5b of the user terminal 5. Further, the image displayed on the printed wiring board as the symbol mark is superimposed on one of the three images shown in (a) to (c) of fig. 2, which are the image composed of the real image information, the image composed of the partial virtual image information, and the image composed of the full virtual image information, and any one of the three images is selectively displayed, and for example, the type of the image may be designated when the display request of the symbol image data is made, or the three images may be switched by the operation of the user terminal 5 after any one of the images is displayed on the user terminal 5.
On the other hand, in step S33, when the server device 2 does not notify of the input request of the identification code, it is determined that the service user is an unregistered user and the processing is terminated as it is.
Fig. 7 is a flowchart showing an example of a processing procedure of the server apparatus 2 when a display request of symbol image data is made by the user terminal 5.
Upon receiving the display request of the symbol image data from the user terminal 5 (step S41), the server apparatus 2 makes an input request of the ID and the password to the user terminal 5 (step S42), checks the ID and the password input from the user terminal 5 with the registration information of the ID stored in the database 3 (step S43), and when the result of the check is not matched (step S44), notifies the user terminal that the result of the check is not matched (step S45), and ends the processing.
On the other hand, when the verification result is the match, an identification code input request is made to the user terminal 5 (step S46), and when an identification code is input from the user terminal 5 in response (step S47), the following verification is performed with reference to the board information stored in the database 3: whether or not the identification code notified by the user who has made the display request of the symbol image data by associating the symbol image data with the identification code is registered (step S48). If the result of the collation does not match, the case where the result of the collation does not match is notified (step S49), and the process ends.
On the other hand, if the identification code is registered in association with the user who has made the display request of the symbol data, the process proceeds to step S50, where the substrate information on the substrate identified by the identification code stored in the database 3 is detected, and the searched various information is transmitted to the user terminal 5. The process then ends.
Note that, although the description has been given of the case where the display request of the symbol image data as the substrate information is made, when the pattern data or the design data is displayed, for example, instead of the display request of the symbol image data as the substrate information, the display request of the data to be displayed, such as the pattern data, the design data, and the SPEC data, may be made and the user terminal 5 may be displayed in the same order as described above.
Next, an example of a processing procedure of the charge management performed by the server device 2 will be described.
The server device 2 stores the number of days elapsed since the date registered as the service user in association with the printed wiring board sold for the user registered as the service user, and charges the fee every time the predetermined number of days elapsed, and notifies the user of the fee.
Fig. 8 is a flowchart showing an example of the processing procedure of the charge management executed by the server device 2.
In the server device 2, for example, at the timing when an ID registration request is made from the user terminal 5, information for specifying the user of the request source, such as an ID and a password, is stored in the database 3 in association with the identification code of the printed wiring board sold to the user of the request source. In addition, the server device 2 counts the number of elapsed days from the ID registration day (step S51).
And, if the user has not notified the deregistration of the utilization of the service, moves from step S52 to step S53, and if the number of elapsed days does not exceed the threshold, returns to step S52. If the number of elapsed days exceeds the threshold value, the flow proceeds to step S54, and the user is notified of the charging and the charging process such as charging. And then returns to step S52.
When the user releases the service registration, the process proceeds from step S52 to step S55, and the process is performed when the registration is released, for example. As the processing at the time of registration release, for example, various information such as an ID and a password stored in association with the user, an identification code of a printed wiring board to be sold, and the number of days elapsed since the ID registration date is deleted, and the like are performed. The process then ends.
Fig. 9 shows an example of a printed wiring board PWB to be managed in the board information providing system 1.
As shown in fig. 9, no symbol marks showing the model, manufacturer, specification, and the like of the mounted electronic component are formed on the printed wiring board PWB. The identification code 50 is formed so as to be readable by OCR such as a digital camera and a reader. For example, the pattern is formed by a method of forming, for example, 8-bit numbers by etching, a method of forming 8-bit numbers by removing a solder resist by laser or the like, a method of printing 8-bit numbers by inkjet printing, or the like. The identification code 50 is preferably formed as etched characters, solder resist free characters. By displaying the identification code 50 as etched characters or solder resist free characters in this manner, the identification code 50 can be marked without increasing the cost. When the identification code 50 is designated, it is preferable to arrange characters so as to be readable by OCR. Such a character arrangement is preferable from the viewpoint of usability because the recognition code can be read using the existing OCR.
The identification code 50 may be displayed by a two-dimensional code such as a QR code (registered trademark). In this case, the display on the printed wiring board may be performed by a laser printer, a symbol inkjet printer, or the like.
In the printed wiring board PWB formed in this way, it is difficult to identify where the component is mounted by referring to the printed wiring board PWB alone, and it is also difficult to analyze and repair the component when an abnormality occurs.
Here, the user uses a camera mounted on the user terminal 5 such as a smartphone to photograph the identification code 50 printed on the printed wiring board PWB. Specifically, first, a display request of symbol image data is made and an ID and a password are input. When the server device 2 checks the ID and the password and requests the input of the identification code, the user performs photographing using the user terminal 5. The identification code is analyzed from the photographed image information, and the image information is transmitted from the user terminal 5 to the server device 2. The user specifies which of the image data composed of the actual image information, the image data composed of the partial virtual image information, and the image data composed of the full virtual image information is to be displayed as the symbol image data, as shown in fig. 2 (a) to (c).
The server device 2 refers to the board information in the database 3 to determine whether or not the received identification code is registered in association with the user identified by the ID and the password, and if the identification code is registered, reads out the image data of the designated display mode corresponding to the printed wiring board identified by the identification code from the database 3 and outputs the image data to the user terminal 5.
As a result, an image in which the symbol mark is superimposed on the printed wiring board is displayed on the display screen of the user terminal 5 in any one of the modes (a) to (c) of fig. 2. The user can easily recognize which component is mounted at which position on the printed wiring board by referring to the display screen. The user can easily recognize the symbol mark of a desired portion in the printed wiring board by performing, for example, enlargement, reduction, rotation, vertical and horizontal movement, a-plane/B-plane switching, and the like in the user terminal 5.
In this way, since no symbol mark is actually written on the printed wiring board, it is not easy for a third person to know which component is mounted at which position even when referring to the printed wiring board. Therefore, it is possible to make it difficult for a third person to analyze the circuit structure of the printed wiring board.
Further, since it is not necessary to directly describe the symbol mark on the printed wiring board, a step of forming the symbol mark is not necessary. As a result, the use of ink, tools, energy, and the like required for forming the symbol mark can be reduced. That is, this can reduce the time required for manufacturing the printed wiring board, and can reduce the cost and save resources.
Further, since it is not necessary to form a symbol mark on the printed wiring board, a symbol mark forming process is not necessary, and a printed wiring board which is discarded due to a failure in the symbol mark forming process can be reduced. As a result, cost reduction and resource saving can be achieved accordingly. In addition, in the printed wiring board intended for mass production, an example is also considered in which the symbol mark is formed on the printed wiring board only in the trial production stage and the symbol mark forming process is omitted in the mass production stage.
In addition, in recent years, with the increase in density of printed wiring boards, the space for forming the symbol mark is reduced or the symbol mark overlaps with the component mounting portion, which makes the design difficult. According to the present invention, even if no symbol mark is formed on the actual printed wiring board, the printed wiring board image on which the symbol mark is superimposed can be referred to on the display screen of the user terminal 5. When reading out the symbol marks from the CAD data or the like and displaying them in superimposition with the actual image (photographed image) or CAD image of the printed wiring board, all the symbol marks may be displayed at the same time, or only the designated symbol marks may be displayed at the same time. Therefore, for example, by designating the user terminal 5, only a part of the symbol marks may be displayed in a superimposed manner, and as a result, the symbol marks having a larger amount of information can be displayed in a superimposed manner on the printed wiring board without being overlapped with each other, as compared with the case where the symbol marks are actually formed on the printed wiring board. In addition, since the formation position of the symbol mark where the symbol marks overlap with each other is not limited, the degree of freedom in designing the arrangement position of the symbol marks can be increased.
In addition, when the symbol marks are displayed in a superimposed manner, the user does not need to manually input the identification code, and the identification code can be simply photographed by the user terminal 5 such as a smartphone.
Further, since the identification code can be manually input to display the symbol mark in a superimposed manner, even if the target printed wiring board is not actually around, an image in which the symbol mark is displayed in a superimposed manner on the printed wiring board can be displayed on the user terminal 5. Therefore, for example, even if the failed printed wiring board is not around, the user terminal 5 can be referred to and analyzed, and the convenience of use can be improved.
In addition, when the symbol marks are actually formed on the printed wiring board, even if the symbol marks overlap each other and it is difficult to read the symbols, the symbols can be read without overlapping by performing enlarged display on the user terminal 5. Therefore, even when the printed wiring board is wired at a high density, the symbol mark can be read, and even a symbol mark formed at a position where the lower side of the component is not visible after the component is mounted, the symbol mark can be reliably read, thereby improving the convenience of use.
Moreover, the customer is managed by associating the customer with the printed wiring board purchased by the customer, based on the charging information. Therefore, by deleting the information on the user whose service use is released at the time of the release or at the time when a certain period has elapsed after the release, it is possible to prevent unnecessary information from being continuously stored in the database 3 and occupying the physical memory.
Note that the symbol mark is mainly information required when a failure occurs or the like, and may be discarded without being referred to once or the like depending on the printed wiring board. In this way, the printed wiring board can be efficiently generated by not forming a symbol mark on the printed wiring board, which may not be referred to at one time, but providing only the symbol mark superimposed and displayed on the printed wiring board as image information to a user when necessary.
In addition, the server device 2 manages the ID and the password of the user in association with the identification code of the printed wiring board sold to the user as board information, and outputs the board information corresponding to the identification code to the user of the request source only when the ID and the password of the user of the request source are associated with the identification code to be notified and stored in the database 3 when the board information is requested. Therefore, for a user who has not purchased a printed wiring board identified by the identification code, it is possible to avoid the need for substrate information relating to the printed wiring board. That is, it is possible to avoid providing unnecessary information to a third person who has not purchased a printed wiring board.
In addition, the server device 2 associates, as substrate information, information relating to the printed wiring substrate, such as inspection history and SPEC data, with the symbol mark corresponding to the printed wiring substrate specified by the identification code. Therefore, not only the symbol mark but also information that cannot be marked in normal symbol printing can be provided. In particular, when analysis is performed when a failure occurs, it is necessary to perform analysis by referring to information other than the symbol flag such as an inspection history. Therefore, not only the symbol mark but also information on the printed wiring board can be easily referred to, and thus analysis can be efficiently performed.
In the above-described embodiment, when the substrate information is referred to, for example, in the case of a failure, the substrate information may be provided so that the user can recognize the order of analysis or repair, for example, to facilitate failure analysis.
In the above-described embodiment, the case where the user is charged for a certain number of passing days has been described, but the present invention is not limited to this. For example, the fee may be charged for each information provision, and the charged content may be changed according to the content of the information provision or the number of information provision.
