摘要: SiC(碳化硅)材料作为第三代半导体材料,具有高结温、高临界击穿电压、高热导率等特点,因此,SiC材料有利于实现功率模块的小型化并提高功率模块的高温性能。基于此,同时为了实现模块的自主可控化,将Si模块中的Si二极管用自主SiC二极管进行替代,制作SiC混合功率模块。主要介绍混合功率模块封装工艺的关键工序:回流、铝线键合、点胶、灌胶。

关键词: SiC, 功率模块, 回流, 键合, 点胶, 灌胶

Abstract: SiC materials as the third generation of semiconductor materials, which with high junction temperature and the critical breakdown voltage, high heat conductivity, etc, is advantageous to realize the miniaturization of power module, and improve the high temperature performance of the powermodule. Based on this, make SiC hybrid power module with autonomous SiC diode which replace Si diode in order to achieve independent controllability. Key packaging process of hybrid power module is introduced in this paper, whichmainly contains reflow soldering,Al wire bonding, adhesive dispense, sealant pouring.

Key words: SiC, power module, reflow soldering, wire bonding, adhesive dispense, sealant pouring
