Description

Electronic component sorting system

The present invention relates to a technology for supplying or recycling electronic components between sorters that perform processes different from each other.

The electronic components produced in the middle stage are delivered to the final product after being completed by various processing procedures. An apparatus that processes electronic components in order to execute the above-mentioned predetermined processing job is collectively referred to as a sorter. Here, the so-called predetermined processing operation is a process performed on electronic components regardless of the type of operation, and may include: high temperature test, low temperature test, normal temperature test, DC test, waxing process, washing process, Sawing processing, coating film processing, blowing processing, and the like.

The present invention is related to all sorting machines, but in order to avoid the inconvenience of the description and to help a clearer understanding, the following is a description of the various sorting machine types used in the test operations of the produced semiconductor elements A sorting machine is demonstrated as an example.

The sorting machine for testing semiconductor devices is similar to Korean Laid-Open Patent No. 10-2007-0021357. After moving the semiconductor components stored in the supply stacker to the test tray, the semiconductor device is placed on the test tray. It is tested and supported by a tester, and the semiconductor device that has completed the test is stored again in a stacker for recycling. in Here, the semiconductor device is stored in a stacker for supply or a stacker for recycling in a state of being mounted on a customer tray serving as a transfer tray.

In addition, the test operation of the semiconductor device may include a normal temperature test operation, a high temperature test operation, and a low temperature test operation based on the temperature environment, and may include a variety of test operations for different electrical characteristics. Therefore, depending on the environment in which the semiconductor device is used, there may be cases in which delivery can only be performed after various tests.

In most cases, packaged semiconductor components are delivered after high and low temperature tests. In this case, it is necessary to perform a low-temperature test again on the semiconductor device that has completed the high-temperature test. For this reason, the sorter has all of the high-temperature test mode and low-temperature test mode, as in Korean Published Patent No. 10-2015-0103512 (hereinafter referred to as "the prior art"), and therefore supports electronic components according to the mode conversion High temperature test or low temperature test.

However, the mode conversion between the high-temperature test mode and the low-temperature test mode takes a considerable amount of time, so the operating rate of the sorter is significantly reduced, and due to the environment between high and low temperatures, the durability of the internal components will also be reduced. reduce.

Even so, it cannot be equipped to support the first test (for example, a high temperature test) in order to perform two or more tests, as in Korean Laid-Open Patent No. 10-2016-0034148 (hereinafter, referred to as "the prior art"). A first support section and a second support section for supporting a second test (for example, a low temperature test). The reason is that if the size of the support unit on one side is small as in the prior art, it is okay, but if both sides are The size of the support department is similar and larger, and the equipment becomes bulky and difficult to carry and set up. Furthermore, it is difficult to perform a test on only the other side of a semiconductor element that does not need to perform the test on either side of the first test or the second test, or that has been tested on one side by other equipment. That is, compared with the sorting machine according to the prior art, the usability is also very low because it can only be applied to semiconductor elements that must pass the second test after the first test.

Therefore, the prior art is a technology that cannot be applied to a semiconductor device that must undergo a variety of tests or processing procedures. Of course, the technical background of the sorting machine for testing semiconductor devices is also applicable to all electronic components.

The present invention has been made in order to solve the above problems, and has the following objects.

First, there is provided a technology capable of minimizing the waiting time between the processing programs and improving the operation rate of the sorting machine.

Second, there is provided a technology regarding a sorter capable of selectively combining and processing a plurality of processing programs of different kinds from each other.

Third, by providing a program that processes a plurality of processing programs of different types from each other, even if one of the specific processing jobs is interrupted, the remaining processing jobs can be executed, so that the sorting machine can be further improved. Run rate technology.

An electronic component sorting system according to the present invention for achieving the above-mentioned object includes: a first sorter that executes a first place for electronic components A second sorting machine that performs a second processing different from the first processing on an electronic component that has performed the first processing by the first sorting machine; an intermediate processing machine that is provided in the first sorting machine and Between the second sorting machine, a receiver function that receives electronic components that have completed the first processing through the first sorting machine located at the front end, and provides electronic components that need to be processed to the second An Offer function of the second sorter located at the back end; and a controller that controls the first sorter, the second sorter, and the intermediate processor.

The electronic component sorting system further includes a conveyor that transfers the electronic components that have performed the first processing in the first sorting machine to the second sorting machine, and the controller is based on the first sorting machine. Or the operating state of the second sorting machine to keep the intermediate processor in a dormant state or in an operating state, so as to control the normal movement of electronic components through the conveyor and the electronics through the intermediate processor Irregular movement of parts.

The first sorting machine includes: a first processing unit that performs a first process on an electronic component that requires the first process; and a loading unit that loads the electronic component that needs the first process to the first processing unit, The second sorting machine includes: a second processing unit that performs a second process on an electronic component transmitted through the conveyor or the intermediate processor; and an unloading unit that unloads the passed processing from the second processing unit. The second processing unit completes the second-processed electronic component.

The controller controls the intermediate processor such that the intermediate processor provides the second sorter with electronic components received through a receiver function through a supplier function.

The controller controls the intermediate processor such that the intermediate processor selectively performs any one of a receiver function and a supplier function.

The controller controls the intermediate processor in such a manner that, if a malfunction occurs at the second sorting machine, the controller causes the intermediate processing machine to perform receiving of the completed first phase transmitted from the first sorting machine. A receiver function of a processing electronic component; if a malfunction occurs in the first sorting machine, causing the intermediate processing machine to perform providing the second sorting machine at the back end with the electronics that need to be processed secondly The supplier function of the part.

The intermediate processing machine includes: a pick-up module that grips or releases the electronic component that has completed the first processing, thereby moving the electronic component to a required position; and a containing module that holds the first component Electronic components transmitted from the sorting machine, or electronic components to be provided to the second sorting machine.

The electronic components stored in the storage module are stored in a state of being mounted on a transport tray.

The present invention has the following effects.

First, since each sorter can be separated and carried and installed, it is easy to carry and install.

Second, since a variety of processing programs can be implemented in series and continuously, the waiting time can be minimized, and even if a specific job is interrupted, the remaining processing jobs can be performed, so the operating rate of the sorting machine can be eventually improved.

Third, it can be used with only one sorter or a combination of multiple sorters, so it has excellent applicability.

Fourth, in an overall sorter system using multiple sorters, it is possible to omit any one or more processing operations for electronic components from a plurality of processing programs each of which is responsible for.

For reference, for brevity of description, known or repeated descriptions are omitted or compressed as much as possible.

<First Embodiment>

FIG. 1 is a schematic plan configuration view of an electronic component sorting system 100 (hereinafter, simply referred to as a “sorting system”) according to an embodiment of the present invention.

The sorting system 100 according to the first embodiment includes a first sorting machine 110, a second sorting machine 120, an intermediate processing machine 150, and a controller 160.

The first sorting machine 110 is equipped with a conventional type as follows: After moving the electronic component loaded on the customer tray to the test tray, the electronic sorter 110 supports the electronic component to be subjected to a high temperature test while the electronic component is loaded on the test tray. (First processing operation), and the electronic component that has completed the high temperature test is moved from the test tray to a vacant customer tray located at the unloading position UP. Here, the customer tray is a conveyance tray for conveying electronic components. This first sorter 110 can be divided into a loading section 111 and a first test support section 112.

The loading section 111 loads a customer tray on which electronic components to be tested are loaded into the first test support section 112. As will be described later, the loading section 111 is preferably a mounting section 111 detachably coupled to the first test support section 112.

The first test support section 112 loads the electronic components loaded on the test tray to the test tray, and connects the electronic components loaded on the test tray to the test machine. Then, the electronic component that has completed the high temperature test is moved from the test tray to the customer tray located at the unloading position UP.

Similarly, the second sorting machine 120 is equipped with a sorting machine of the same type as in the prior art. After the electronic components loaded on the customer tray are moved to the test tray, the electronic components are subjected to a low temperature test while being loaded on the test tray. Support (second processing operation) and move the electronic components that have completed the low temperature test from the test tray to the customer tray. This second sorter 120 can be divided into a second test support unit 122 and an unloading unit 123.

The second test support unit 122 moves the electronic components of the customer tray located at the loading position LP to the test tray, connects the electronic components loaded on the test tray to the tester, and then moves the electronic components that have completed the low temperature test to the customer tray.

The unloading unit 123 unloads the customer tray on which the electronic components that have been subjected to the low temperature test are loaded, from the second test support unit 122. Such an unloading portion 123 may preferably be considered as an unloading portion 123 removably coupled to the second test support portion 122.

If additional explanation is given, like the conventional sorting machine for testing semiconductor devices, the loading section and the unloading section 123 have a stacker capable of accommodating customer trays. Therefore, the loading section 111 can load the first test support section 112 with electronic components. The customer tray, and the unloading section 123 may unload the customer tray from the second test support section 122.

The intermediate processor 150 is provided between the first sorter 110 and the second sorter 120. The above-mentioned intermediate processor 150 performs a receiver function of receiving the electronic components that have completed the first processing from the first sorter 110 at the front end and provides the electronic components that have completed the first processing to the second sorter at the back end. Offer function. To this end, the intermediate processor 150 includes an unloader 151, a loader 152, a set plate 153, a frame 154, a first coupler 155a, and a second coupler 155b.

The unloader 151 unloads a customer tray loaded with electronic components that have undergone a high temperature test in the first sorter 110 from the first sorter, and places it on a return tray 153. To this end, the unloader 151 may include a transfer 151 a and a rotator 151 b as shown in the schematic side view of FIG. 2.

The adapter 151a includes a gripping head 151a-1 and a lifter 151a-2.

The grasping head 151a-1 can grasp or release the customer tray. Such a gripping head 151a-1 is well known by Korean Patent No. 10-0715469 and the like, and therefore a detailed description thereof is omitted.

The lifter 151a-2 raises and lowers the grasping head 151a-1.

The rotator 151b rotates the grasping head 151a-1 and the lifter 151a-2 by 180 degrees with the vertical axis as a rotation axis.

After the unloader 151 grasps the customer tray CT located at the unloading position UP of the first sorter 110 as shown in FIG. 3, the unloader 151 operates the rotator 151 b as shown in FIG. 4 to move the grasping head 151 a-1 and the lifter 151 a. -2 Rotate 180 degrees, and operate the lifter 151a-2 as shown in FIG. 5 to place the customer tray CT on the return tray 153. Accordingly, the customer tray CT originally located at the unloading position UP of the first sorter 110 is transferred to the return tray 153. Of course, the customer tray CT arranged on the return tray 153 is loaded with electronic components that have completed the first test.

The loader 152 holds the customer tray CT from the return tray 153 and moves it to the loading position LP of the second sorter 120. This loader 152 moves the customer tray CT located on the return tray 153 to the loading position LP of the second sorter 120. Except for this point, the substantial structure is the same as that of the unloader 151, so the description thereof is omitted. .

The return tray 153 is a position where the customer tray CT waits temporarily before moving to the second sorter 120. That is, the return tray 153 can perform a role of temporarily placing the customer tray CT in order to transfer the customer tray CT from the unloader 151 to the loader 152.

The frame 154 constitutes the skeleton of the intermediate processing machine 150, and is provided with an unloader 151, a loader 152, and a return tray 153.

The first coupler 155a and the second coupler 155b are provided to couple the frame 154 to the first sorter 110 and the second sorter 120. The first coupler 155a and the second coupler 155b may be provided in the form of an ordinary hook or other locking devices.

According to this intermediate processing machine 150, the electronic components that have completed the high temperature test are directly transferred from the first sorting machine 110 to the second sorting machine 120 in a state of being loaded on the customer tray CT, so that the second sorting machine 120 can be implemented. Low temperature test. That is, when the intermediate processing machine 150 is used, the high temperature is completed The tested electronic components can be continuously cold-tested with minimal waiting time.

The controller 160 controls the first sorter 110, the second sorter 120, and the intermediate processor 150 to be able to continuously execute the second process after the first process for the electronic components is completed.

In addition, in the above-mentioned embodiment, the electronic components are transferred from the first sorter 110 to the second sorter 120 in a state of being loaded on the customer tray CT. However, depending on the type of processing operation and the type of electronic components, it is of course possible to consider a structure in which the electronic components themselves are transferred from the first sorting machine to the second sorting machine.

For reference, the customer tray used in the loading section 111 of the first sorting machine 110 is removed from the first sorting machine 110 according to the types of processing jobs realized in the first sorting machine 110 and the second sorting machine 120. The customer tray passed to the second sorter 120 and the customer tray used in the unloading section 123 of the second sorter 120 may be the same or different. That is, although in the above-mentioned embodiment taking the high-temperature test and the low-temperature test as examples, it is preferable to make all the customer trays CT as the transporting trays have the same form, for example, if the first sorting machine is to perform the change of electronic components In the sorting machine with the processing of the shape, the electronic components change the shape through the first processing, so the customer tray used in the unloading department and the customer tray transferred from the first sorting machine to the second sorting machine will be different.

In addition, as described above, when the loading section 111 has a structure detachably coupled to the first sorter 110 and the unloading section 123 has a structure detachably coupled to the second sorter 120, the first sorting Machine 110 The positions of the second sorting machine 120 and the second sorting machine 120 are completely interchangeable. Like the above-mentioned modification, various combinations of the first processing program and the second processing program can be realized. Furthermore, if the first sorter 110 and the second sorter 120 are equipped to support a high-temperature test or a low-temperature test by changing the test mode, or configured to implement a mode switch to perform other types of tests, The more diverse combinations of the first processing program and the second processing program make their applicability better.

Furthermore, according to the present invention, for example, if jam occurs in the loading section 111, only the operation of the loading section 111 can be interrupted, and the rear end thereof can be continuously operated. In addition, quickly repairing the clogged part in this state can ultimately improve the operating rates of the first and second sorters 110 and 120.

Furthermore, if the loading section 111 is detachably coupled, for example, even if a fatal defect other than a blockage occurs in the loading section 111, only the loading can be quickly replaced while the rear end of the loading section 111 is continuously operating. The unit 111 can finally improve the operating rates of the first and second sorters 110 and 120. Even in the case where there is no replaceable redundant loading section 111, the test supporting section 112 is simply passed to the test support section 112 by the operator's manual operation (or automatic transfer trolley) after removing the loading section 111 from the first test support section 112. By supplying the customer tray CT, the operation rate of the first sorter 110 and the second sorter 120 can also be improved. Of course, at the same time as the manual operation, the repair of the failed loading section 111 should be started. For this loading section 111 The description of the advantages of the unloading structure can also be applied to the description of the advantages of the unloading structure of the unloading section 123 of the second sorter 120.

FIG. 6 shows an example in which three sorters 110, 120, 130 and two intermediate processors 150 are used. As shown in FIG. 6, the present invention is not necessarily limited to the continuous execution of two mutually different processing jobs. Three or more processing jobs different from each other are continuously executed.

For reference, as shown in FIG. 6, the front end and the rear end of the sorting machine with the reference numeral 150 are all combined by the intermediate processing machine 150, and therefore it is preferable to equip the loading section or the unloading section so that they can be inevitably loaded and unloaded. In this case, only the test support unit is integrated into the overall system in a state where the loading unit and the unloading unit are all removed.

Of course, the intermediate processing machine 150 according to the present invention may be configured so that electronic components can also be transferred between the sorting machines having all of the loading section and the unloading section. For example, when the unloading unit of the first sorting machine and the loading unit of the second sorting machine fail, the intermediate processing machine may be configured to perform unloading work and loading work in place of the unloading unit and loading unit. Furthermore, in a case where the structure in which the first sorting machine and the second sorting machine are directly combined to move the electronic components from the first sorting machine to the second sorting machine, the following structure can also be produced : When the moving result fails, the intermediate processing machine is located between the first sorting machine and the second sorting machine, so that the intermediate processing machine can move the electronic component instead of the faulty moving structure.

<Another example for an intermediate processor>

FIG. 7 is a schematic plan view of an intermediate processor 150 'according to another example.

The intermediate processor 150 'of FIG. 7 includes an unloader 151', a loader 152 ', a mover 153', a frame 154 ', a first combiner 155a', and a second combiner 155b '.

The unloader unloads the customer tray on which the electronic components having been subjected to the high temperature test through the first processing operation of the first sorter 110 from the unloading position UP of the first sorter 110 and places it in the first position P1 .

The loader 152 ′ grips the customer tray located at the second position P2 and moves it to the loading position LP of the second sorter 120.

The mover 153 'moves the customer tray placed at the first position P1 by the unloader 151' to the second position P2.

The frame 154 'constitutes the skeleton of the intermediate processing machine 150', and is provided with an unloader 151 ', a loader 152', and a mover 153 '.

The first and second combiners 155a 'and 155b' are the same as the first and second combiners 155a and 155b in the intermediate processor 150 of Fig. 1.

According to the intermediate processor 150 'based on the second embodiment as described above, the operation interference between the unloader 151' and the loader 152 'can be completely eliminated, and thus the safety of the device can be improved.

<Second Embodiment>

FIG. 8 is a schematic plan configuration view of a sorting system 200 according to a second embodiment of the present invention.

This embodiment is substantially similar to the first embodiment, but additionally includes a conveyor 240 that directly transfers electronic components from the first sorter 210 to the second sorter 220.

The sorting system 200 according to the second embodiment includes a first sorter 210, a second sorter 220, a conveyor 240, an intermediate processor 250, and a controller 260.

The first sorter 210 is equipped to support the high temperature test and, as in the prior art, supports the following. After the electronic components loaded on the customer tray are moved to the test tray, the electronic components are subjected to the high temperature test while the electronic components are loaded on the test tray. (First processing operation), and the electronic component that has completed the high temperature test is moved from the test tray to an empty customer tray located at the unloading position UP. This first sorter 210 is divided into a first loading section 211, a first test support section 212, and a first unloading section 213.

The first loading section 211 loads a customer tray on which electronic components to be tested are loaded into the first test support section 212.

The first test support unit 212 loads the electronic components loaded on the customer tray onto the test tray, connects the electronic components loaded on the test tray to the testing machine, and then moves the electronic components that have completed the high temperature test from the test tray to The customer tray at the unloading position UP.

The first unloading section 213 unloads the customer tray located at the unloading position UP from the first test support section 212 and supplies it to the conveyor 240.

The second sorting machine 220 supports the movement of the electronic components loaded on the customer's tray conveyed by the conveyor 240 to the test tray as follows. Then, a low-temperature test (second processing operation) is performed while the test piece is loaded on the test tray, and the electronic components that have completed the low-temperature test are moved from the test tray to the customer tray. Similarly, the second sorter 220 is divided into a second loading section 221, a second test support section 222, and a second unloading section 223.

The second loading section receives the customer tray from the conveyor 240 and loads it into the loading position LP of the second test support section 222.

The second test support unit 222 moves the electronic components of the customer tray located at the loading position LP to the test tray, connects the electronic components loaded on the test tray to the tester, and then moves the electronic components that have completed the low temperature test to the customer tray.

The second unloading unit 223 unloads the customer tray on which the electronic component that has completed the low temperature test is loaded from the second test support unit 222.

Like the first embodiment, the first loading section 211 and the second unloading section 223 are provided with a stacker capable of accommodating a customer tray.

The conveyor 240 provides the second sorter 220 with the customer tray received from the first sorter 210. To this end, the conveyor 240 includes shuttle tables 241a and 241b capable of reciprocating in the front-rear direction. Therefore, if the first unloading portion 213 moves the customer tray located at the unloading position UP to the moving tables 241a and 241b located forward, the moving tables 241a and 241b move backward and the second loading portion 221 moves the rear portion The customer tray of the tables 241a, 241b moves to the loading position LP

For reference, in this embodiment, the load is transferred from the first sorting machine 210 to the second sorting machine 220 through the mobile worktables 241a and 241b. The configuration of the electronic component in a state where it reaches the customer tray, but depending on the size or type of the electronic component, it can be considered that the electronic component itself is configured to move.

Also, in this embodiment, the case where the conveyor 240 is separately distinguished from the first sorter or 210 or the second sorter 220 is shown, but according to the fact that the conveyor 240 can be separated from the first sorter The machine 210 is integrally integrated, so as to be equipped as a part of the first sorting machine 210, and can also be integrated as a part of the second sorting machine 220, so as to be equipped as a part of the second sorting machine 220. It is integrated with the intermediate processing machine 250 so as to be equipped as a part of the intermediate processing machine 250.

The intermediate processor 250 is provided between the first sorter 210 and the second sorter 220 and performs a receiver function of receiving a customer tray from the conveyor 240 and a supplier function of providing a customer tray to the second sorter 220 . To this end, as shown in FIG. 9, the intermediate processing machine 250 includes a pickup module 251, a mover 252, a receiving module 253A, an accessor 253B, a frame 254, a first coupler 255 a and a second coupler 255 b.

The pick-up module 251 can hold the customer tray, or it can release the holding and move the held customer tray to a desired position.

The mover 252 is provided to move the customer tray in the left-right direction to prevent operation interference between the pickup module 251 and the second loading portion 221. Such a mover 252 also has a moving table 252a that can move in the left-right direction in order to move the customer tray.

Containment module 253A accommodates customer trays.

The access tray 253B introduces the customer tray into the accommodation module 253A, or draws out the customer tray from the accommodation module 253A.

The frame 254, the first coupler 255a, and the second coupler 255b are the same as the frame 154, the first coupler 155a, and the second coupler 155b in the first embodiment, respectively, and a description thereof will be omitted.

The controller 260 controls the above-mentioned first sorter 210, second sorter 220, conveyor 240, and intermediate processor 250. In particular, the controller 260 operates in a normal movement mode or an irregular movement mode in order to move the electronic components in accordance with an operating state such as good or bad operation of the first sorter 210 and the second sorter 220. In the following, normal movements and two kinds of irregular movements of electronic components that can be realized in the sorting system 200 according to the present embodiment will be described.

1. Normal mobile mode

In the normal movement mode, the electronic components are directly moved from the first sorter 210 to the second sorter 220. That is, the electronic components that have completed the first processing in the first sorter 210 are supplied to the second sorter 220 at the rear end via the conveyor 240 in a state of being loaded on the customer tray. In this normal movement mode, the controller 260 keeps the intermediate processor in a sleep state.

2. The first irregular movement pattern

The first irregular movement mode is selected when it is necessary to omit the first processing of the electronic components through the first sorter 210 or when a malfunction occurs in the first sorter 210. In this first irregular movement mode, the operation of the first sorter 210 and the conveyor 240 It is suspended, and the intermediate processor 250 operates in a manner that performs an offer function.

The customer's tray on which the electronic components to be subjected to the second process are carried is carried into the storage module 253A by an operator (or an automatic cart). According to this, the access device 253B sequentially draws out the customer tray from the storage module 253A from the customer tray located at the uppermost end of the storage module 253A and moves it to the access position IO. Then, the pick-up module 251 grasps the electronic components of the customer tray from the entry / exit position IO and moves it to the mobile table 252a of the mobile position MP located on the right side, and the mobile table 252a moves to the provided position OP on the left side. Next, the second loading section 221 operates to hold the electronic component from the supply position OP, and loads it into the second test support section 222. According to the embodiment, it can be realized that the pickup module 251 or the customer tray itself can be moved from the access position IO to the moving position MP according to the type of electronic components, or it can be realized that the second loading unit 221 moves the customer tray itself from the provided position OP Loaded into the second test support section 222.

That is, in the first irregular movement mode, the electronic components accommodated in the accommodation module 253A move along the path of the loading position LP of the second sorter 220 via the access position IO, the movement position MP, and the supply position OP. mobile. Here, the moved electronic component is an electronic component that does not require the first process or has completed the first process.

3. The second irregular movement pattern

The second irregular movement mode is selected when it is necessary to omit the second processing of the electronic components through the second sorting machine 220 or when a malfunction occurs in the second sorting machine 220. In this second not In the regular movement mode, the operation of the second sorter 220 is suspended and the intermediate processor 250 performs a receiver function.

Since the operation of the second sorter 220 is suspended, the second loading section 221 cannot be operated. Therefore, if the electronic components that have completed the first processing are placed on the moving tables 241a and 241b of the conveyor 240 in a state of being loaded on the customer tray, the moving tables 241a and 241b are moved to the pick-up module 251 and can hold the The holding position is followed by the pickup module 251 operating to move the customer tray to the loading / unloading position IO. Furthermore, the access device 253B introduces the customer tray located at the access position IO to the storage module 253A, and if the storage module 253A is filled with the customer tray, the operator (or an automatic trolley) moves the customer tray from the storage module 253A.

In a case where it is necessary to perform a second process on the electronic component that has completed the first process, the operator (or an automatic trolley) supplies the unloaded customer tray to another sorting machine that performs the second process.

Of course, the sorting system according to the aforementioned second embodiment can also be extended to a case of being equipped with three or more sorting machines.

In addition, the conveyor 240 and the intermediate processing machine 250 may be designed in an optimized form according to the type of the electronic component. For example, various components of the conveyor 240 or the intermediate processing machine 250 may be formed according to the shape or size of the electronic component. Was added or omitted.
