国产压接式电力电子模块的改良

The Improvement of National Power and Electronic Model in Compression Joint

通过对压接式电力电子模块结构分析 ,并结合国外DBC直接键合技术而提出的模块生产改良方法 ,解决了国产模块“软特性”问题 ;并解决了国内电力电子模块实际生产过程中存在的成品率低、回收率高等实际问题 ,使得成品率由一般的 2 0 %左右提高到 95 %以上 。

The approach to solve the problem of soft Characteristics is made out through the structural analysis of the national power electronic model in compression joint and through being combineel with the foreign technology of DBC.It also settles down the practical puzzles of high rate of recovery and low rate of finished product.So it possible to raise the rate of finished product from 20% to 95% and greatly lower the cost of model production.
