中文摘要

本文提出了一种在工厂验收测试及停机维护期间,评估IGBT功率堆完整性的方法。核心挑战在于检测影响功率堆热路径的常见装配问题,并有效区分键合线脱落与焊层剥离等老化效应。

English Abstract

This paper proposes a method for assessing the integrity of a series of insulated-gate bipolar transistor (IGBT) power stacks during factory-acceptance tests and service stops. The key challenge that is addressed in this paper is detecting common assembly issues that affect the power stack thermal path as well as distinguishing the acute aging effects of bond-wire lift-off and solder delamination....
