AI Technical Summary

Technical Problem

Existing IGBT packaging technology suffers from problems such as poor heat dissipation, high cost, easy breakage of ceramic insulation layer, and assembly difficulties. In particular, when using SMT process, it is difficult to achieve stable fixation and good insulation.

Method used

The design employs a first and second bracket made of different materials. The IGBT is tightly fixed between the circuit board and the heat dissipation interface using fasteners. The extension of the second bracket and the top abutment are used to achieve insulation barrier, and the fasteners are used for quick fastening and fixing, thereby reducing the overall thickness and improving heat dissipation efficiency.

Benefits of technology

This achieves stable fixing of IGBTs, rapid assembly, reduced overall size and cost, while meeting electrical safety requirements and improving heat dissipation and insulation performance.
