Problems solved by technology

[0002] In the production process of traditional power modules, since there is no two-dimensional code marking on the substrate and DBC, the production process can only be traced back to the batch information, but not to the information of each power module; Manual selection is required when calling the program, so there is a risk of error

Embodiment

[0025] Example: figure 1 As shown, print a QR code with information such as the product model, batch number, and list number of the batch on the production work order. The engineer needs to set up the QR code information and all the programs and methods that need to be called in the production process. At the DBC, substrate and shell marking sites, call the corresponding marking program through the QR code information, and input the batch information. Into the DBC, substrate and shell marking information, and each DBC, substrate and shell has a unique number. In each production process and site that needs to call programs and methods, scan the QR code on the work order to call the corresponding program for production and testing. If the work order information does not match the substrate and DBC configuration information, the device will alarm to prevent products from entering the site.

Abstract

The invention discloses a traceability method of a power module. The traceability method of the power module comprises the steps that: corresponding two-dimensional codes are printed on substrates, DBC and outer shells of power modules as well as a production work order, information of the two-dimensional codes is saved into a computer system, and the information of the two-dimensional codes printed on the substrates, the DBC and the outer shells of the power module as well as the production work order correspond to raw material information saved in the computer system and process information; each two-dimensional code at least comprises a batch product model, a batch number and an inventory number, the two-dimensional codes are printed on the production work order before the production of the power modules, then corresponding marking programs are invoked through the two-dimensional code information at marking sites of the substrates, the DBC and the outer shells later, batch information is input into the marking information of the substrates, the DBC and the outer shells, and the substrate, the DBC and the outer shell of each power module have unique serial numbers; and corresponding programs are invoked for production and testing through scanning the two-dimensional code on the production work order in the production process and at each site requiring to invoke the programs and method.

Description

technical field [0001] The invention relates to a traceability method for a power module, in particular to a traceability method for the entire production process of the power module and testing, packaging, etc., and belongs to the field of power electronics. Background technique [0002] In the production process of traditional power modules, since there is no two-dimensional code marking on the substrate and DBC, the production process can only be traced back to the batch information, but not to the information of each power module; Manual selection is required when calling the program and there is a risk of error. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a simple and reliable method, which can trace the power module information during the process, inspection, testing, packaging, storage, delivery and other processes and when customers complain. Traceability method for power mod...
