摘要

针对目前IGBT 应用质量的评估还没有系统体系的情况，建立牵引IGBT 过程质量评估系统，并结合参数正态性检测、过程能力指数(Cpk)、威布尔分布(Weibull) 等专业分析工具和方法，实施对器件的过程质量评估和器件故障的追溯分析。该研究为器件品质保障及应用质量监管提供了方法和思路。

Abstract

Aiming to the absence of IGBT’s application process quality assessment system, a quality assessment system of traction IGBTs was established, which achieved the process quality assessment and fault tracing analysis by using parameters normality checking, process capability index (Cpk), Weibull distribution and other special tools and methods. This study provided a new idea for device’s quality assurance and its field reliability supervision.
