Description

Technical Field

[0001] The present invention relates to the field of mounting processes, and in particular to the field of production history computer management technology, and specifically to an integrated system for constructing special fixtures and memory module traceability defense. Background Art

[0002] The mounting process uses printed circuit boards for operation. After the cutting process cuts each printed circuit board into a single memory module, the memory module cannot be traced back to which printed circuit board was used in the mounting process, let alone which special fixture was used. The actual situation is that the manufacturing line manages the production history of 600 memory modules in units, but the production history of each PCB printed circuit board and each Module memory module cannot be traced; and the existing TCJ special fixture manual management method does not have the use history of each special fixture.

[0003] The special fixture unloading equipment used in the production line is Korean equipment with a fully enclosed software structure. Without authorization, there is no permission to modify the equipment. In addition, the equipment does not have the function of controlling the equipment to stop when an abnormal special fixture is found. The cost of inviting the equipment supplier to modify it is too high.

[0004] The memory module and the special fixture cannot be traced. After the special fixture used in the production line is deformed, the defects of the upper end of the gold finger of the memory module continue to occur, and flow out to the subsequent processes and customers. After the subsequent processes and customers find out the abnormal feedback, they cannot accurately find out which special fixture caused it, resulting in continuous defects and rework, which leads to reduced customer satisfaction. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide an integrated system for constructing a special fixture and memory module traceability defense, so as to solve the difficulties of the prior art.

[0030] The present invention proposes an integrated system for constructing a special fixture and memory module traceability defense, which is used in the production history tracing process. The present invention does not limit the type of product, but the integrated system for constructing a special fixture and memory module traceability defense is particularly suitable for the production of DDR5.

[0031] In general, the integrated system for constructing a special fixture and memory module traceability defense proposed in the present invention mainly includes a label coding unit, a label attaching unit, a pre-cutting code scanning unit, a post-cutting code scanning unit, a data processing module and a data feedback module. Figure 1 , which shows the arrangement relationship of the label coding unit, the label attaching unit, the pre-cutting code scanning unit, the post-cutting code scanning unit, the data processing module and the data feedback module.

[0032] In order to accurately find out the operation abnormalities, the problem that the memory module and the special fixture cannot be traced in the background technology is solved. After the special fixture used in the production line is deformed, the defective vulnerability on the upper end of the gold finger of the memory module continues to occur and flows out to the subsequent process and the client. After the subsequent process and the client find the abnormal feedback, they cannot accurately find out which special fixture caused it, resulting in continuous defects and rework, causing reduced customer satisfaction. For this reason, in the technical solution provided in this embodiment, corresponding numbers of scanning devices are installed on the TCU equipment and the labeling machine according to the number of labels, and then the TCJ fixtures before and after the PCB board cutting and the labels on a single memory module are recorded, and the records are uniformly bound and uploaded to the server for processing and comparison, so as to realize the individual traceability of the DDR5 product operation history and realize active defense at the same time, which can effectively ensure the quality of online product production. In addition, it can also reduce manual statistics and improve efficiency.

[0033] Specifically, according to the process used in the mounting process, the equipment involved in the code scanning structure includes the primary surface TCU equipment and the secondary surface TCU equipment, and when the TCJ fixture conveys each PCB board, a TCJ upper cover and a TCJ lower cover will be generated accordingly. Therefore, in order to achieve complete product code traceability, three sets of code scanning devices need to be installed on the TCU equipment, and the three sets of code scanning devices are respectively installed on the TCJ upper cover, the TCJ lower cover and the uncut PCB board.

[0034] On this basis, in order to avoid the influence of the barcode on the production process of the TCJ fixture and the uncut PCB board, the barcode on the upper cover and the lower cover of the TCJ fixture is preferably located at the inner end of the fixture, and the barcode on the PCB board is located on the cutting waste line; in addition, the barcode on the TCJ fixture and the uncut PCB board is a QR code, which can be operated by pre-coding or inkjet coding.

[0035] Similarly, in this embodiment, a labeling machine is also needed to label each single memory module after the PCB board is cut. Therefore, it is necessary to verify the data on the label of each PCB board and the single memory module. For this purpose, two sets of scanning devices need to be installed on the labeling machine. Since the labeling content on the single memory module is generated according to the QR code on the corresponding PCB board, the labeling content on the single memory module also uses a QR code to facilitate the consistency of data management.

[0036] On this basis, the scanning device scans and binds the QR codes of each PCB board, the TCJ upper and lower covers on the primary and secondary surfaces, and each individual memory module, and then uploads them. After uploading to the server, the data processing module set in the server compares and feedbacks the information of the scanning unit before and after cutting of the PCB board, and stores it in the server's database.

[0037] It should be specifically explained that the comparison content in the data processing module includes matching the scanning information of the TCU equipment and the labeling equipment and the test information of the post-process. After real-time comparison, the barcode information of the upper cover and lower cover of the TCJ fixture of the same PCB board and the single memory module after the PCB board is cut are bound and stored in the server database. Once a result matching the value in the abnormal library is found, the abnormal information will be prompted through the data feedback module, and the shutdown alarm will be processed.

[0038] When the data feedback module receives the abnormal value returned by the system, the abnormal value includes the information of the corresponding single memory module and is displayed on the monitor in real time. The industrial computer sends a stop signal to the emergency stop or pause button of the equipment through the 485 controller. After the equipment stops, the personnel remove the abnormal TCJ fixture, which can achieve the dual functions of traceability and active quality defense.

[0039] According to on-site operations, the above system can accurately identify TCJ fixtures with abnormal operations, reduce the batch defect rate of the manufacturing production line by 5ppm, and save no less than 13.0K$ / year. At the same time, through the development of computerized systems, systematic management is achieved, manual statistical work is reduced, efficiency is improved, and 750 minutes are saved per month.

[0040] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
