本文介绍了一种利用主成分法分析产品性能特征的策略。特别是，作者与性能特性的可靠性，并提出了一个相对的可靠性度量，这是有用的可靠性筛选。评估了各个性能特征对可靠性的重要性。重要性表明了产品的关键特性和提高产品可靠性的努力方向。他们使用评分图来识别退化模式并确定主要的退化机制。采用主成分分析法对红外发光二极管的老化数据进行了分析。
This paper describes a strategy of using the principal component method to analyze the performance characteristics of products. In particular, the authors relate performance characteristics to reliability and propose a relative reliability metric, which is useful in reliability screening. The importance of individual performance characteristics to reliability is evaluated. The importance indicates the critical characteristic and the direction in which efforts should be made to improve the reliability of a product. They use score plots to identify degradation modes and determine dominant degradation mechanisms. The principal component method is applied to analyze the degradation data of infrared light emitting diodes.
