Abstract

The invention relates to the technical field of IGBT module testing, in particular to an IGBT module testing platform which is characterized in that an IGBT module is fixed to a vibration mechanism through a jig assembly, the vibration environment of the IGBT module during working is simulated through the vibration mechanism, and after vibration for a set time length, the IGBT module is taken out from the jig assembly at the vibration mechanism through a material taking clamp. The IGBT module is conveyed to the jig assembly through the moving mechanism to be fixed, the IGBT module at the jig assembly is detected through the testing mechanism, the vibration working environment of the IGBT module can be effectively simulated through the vibration mechanism, the vibrated IGBT module can be detected through a tester of the testing mechanism, and the testing result is real and reliable.

Description

technical field [0001] The invention relates to the technical field of IGBT module testing, in particular to an IGBT module testing platform. Background technique [0002] IGBT module packaging is to integrate multiple IGBTs together to improve the service life and reliability of the IGBT module. The IGBT module has three connection parts: the aluminum wire bonding point on the silicon wafer, the welding surface between the silicon wafer and the ceramic insulating substrate, and the welding surface between the ceramic insulating substrate and the copper base plate. When the IGBT module is used in automobiles, rail transit and other scenarios, it often encounters continuous vibration, and the continuous vibration will affect the internal connection part of the IGBT module, causing the connection point to be disconnected, thereby affecting the reliability and service life of the IGBT module. Therefore, it is necessary to set up a test platform to test the influence of various...
