The substrate on which the 2D barcode 13 is formed is a substrate assembly 10 on which a plurality of unit substrates 11 are formed. At this time, the substrate assembly 10 is formed such that a plurality of unit substrates 11 of unit sizes are arranged at regular intervals in order to increase the use efficiency and improve productivity.

At the edges of the unit substrates 11, an auxiliary substrate 12 supporting the plurality of unit substrates 11 integrally is provided. That is, the unit substrate 11 and the auxiliary substrate 12 are integrally provided, and the unit substrate 11 is partitioned from the auxiliary substrate 12 so as to be separated.

Here, the unit substrate 11 of the substrate assembly 10 is a substrate before the corresponding component is mounted, and each unit substrate 11 may be different from each other and the same type may be arranged in a constant form.

And the arrangement of the unit substrate 11 is formed so that a plurality of unit substrates 11 can be arranged in a minimum space. Therefore, it may be arranged in a zigzag form or an opposite form or a misaligned form. In addition, the auxiliary substrate 12 is installed in a form surrounding the edges of the unit substrates 11 arranged at regular intervals, and on one side, a 2D bar code 13 having information of the unit substrates 11 is formed. In addition, the substrate assembly 10 is provided with a physical mark 14 for teaching the substrate assembly 10.

In addition, a substrate inspection equipment 30 for inspecting good quality and defects for each of the unit substrates 11 is provided. Here, the board inspection equipment 30 inspects the plane and the back of the board, respectively, and transmits the good and defective information of the board to the server 20, and the server 20 transmits the transmitted unit board 11 information to the serial numbers, respectively. Save it.

At this time, the operator can directly determine the good or bad of the unit substrate and store it in the server 20. In addition, when the test results are provided separately, the worker may directly store the test results in the server 20.

At this time, the information stored as the serial number in the server 20 according to the inspection results are stored according to the good and defective, respectively, each serial number, the manufacturing company, the working time, the worker, the material substrate of the unit substrate 11 The history of the equipment for mounting the unit substrate 11 of the assembly 10 is included.

The serial number is marked on the substrate assembly 10. At this time, the serial number is marked with the 2D bar code 13, the 2D bar code 13 is formed by a separate bar code marker (40). In addition, the 2D barcode 13 includes bad mark information that determines good or bad of each unit substrate 11.

In addition, the 2D barcode 13 itself may include location information and arrangement direction information according to the arrangement of the unit substrates 11. However, the location information and the arrangement direction information of the unit substrate 11 is preferably stored in the serial number stored in the server 20. The barcode marker 40 may be a laser marker.

The component mounter 60 detects the 2D bar code 13 of the substrate assembly 10 formed by the bar code marker 40, determines good or poor, and transmits it to the server 20. In this case, the detection of the 2D barcode 13 acquires an image using the physical camera 61 provided in the component mounter 60, and the recognition module 90 enables the 2D barcode 13 to be recognized from the acquired image. Is provided.

Accordingly, since the 2D barcode 13 needs to acquire an image of the 2D barcode 13 using the physical camera 61, the 2D barcode 13 is formed adjacent to the physical mark 14 taught by the physical camera 61.

In this case, the recognition module 90 may be provided in the physical camera 61 and may be provided in the server 20. Therefore, the 2D barcode image obtained from the dual camera is input to the server 20 using the recognition module 90 as a serial number, and the server 20 provides information corresponding to the serial number to the component mounter 60. . The server 20 updates the serial number of the unit board 11 corresponding to the history of equipment for mounting the unit board 11 of the substrate assembly 10. Here, the history information of all the equipment generated thereafter is updated to the serial number of the server 20 is provided to enable tracking.

That is, the unit board 11 is mounted according to the information of the unit board 11 corresponding to the serial number of the server only when the goods are good, and when the unit board 11 is defective, it is excluded from the component mounting.

In this case, when a plurality of unit substrates 11 are formed, it takes a long time to acquire and recognize all the serial numbers of each unit substrate 11, rather than forming the 2D barcodes 13 on the unit substrates 11, respectively. The unit substrate 11 is formed on the auxiliary substrate 12 that is integrated. Rather than forming 2D barcodes 13 with the same quantity of unit substrates 11 on the auxiliary substrate 12, the serial numbers and the quantity information of all the auxiliary substrates 12 on one 2D barcode 13 are included.

Accordingly, the serial number and the quantity information of the plurality of unit substrates 10 are simultaneously recognized and processed through the recognition module 90 by one 2D bar code 13, and the units in the substrate assembly 10 together with the serial numbers. Non-payment information of all the substrates 11 is stored in the server 20 through the recognition module 90.

In this case, when the information recognized by the recognition module is directly transmitted to the component mounter 60 without passing through the server 20, the component mounter 60 receives the information on the quantity of payment recognized by the recognition module 90 in the 2D bar code 13. It is possible to determine whether the part is mounted.

On the other hand, between the barcode marker 40 and the component mounter 60 is provided a screen printer 50 for soldering to the short-circuit boards 11 of the substrate assembly 10, respectively, the component mounter 60 The chip is mounted on the solder applied by the screen printer 50.
