本文总结了电子产品可靠性预计从20世纪50年代产生至今60多年的发展历史,对已有的电子产品可靠性预计方法进行了分类,对常用的基于协变量模型和基于故障物理模型的两类重要预计方法分别进行了分析和比较。分析结果表明,针对不同特点、处于不同寿命周期阶段以及具有不同可靠性相关信息的电子产品应选取合适的可靠性预计方法,在更加全面和准确地预计其可靠性水平的同时,消除设计与工艺缺陷,提高其可靠性水平。
本文總結瞭電子產品可靠性預計從20世紀50年代產生至今60多年的髮展歷史,對已有的電子產品可靠性預計方法進行瞭分類,對常用的基于協變量模型和基于故障物理模型的兩類重要預計方法分彆進行瞭分析和比較。分析結果錶明,針對不同特點、處于不同壽命週期階段以及具有不同可靠性相關信息的電子產品應選取閤適的可靠性預計方法,在更加全麵和準確地預計其可靠性水平的同時,消除設計與工藝缺陷,提高其可靠性水平。

This paper summarized the development history of more than 60 years of reliability prediction for electronic products since 1950s. Most of the existing methods were included and classified. There are two common and important methods, Covariate-Models-based method and Physics-of-Failure-Models-based method were analysis and compared. The analysis results showed that we should choose proper reliability methods for electronic products with different characteristics, in different stage of life cycle and with different reliability related information, which will help to quantificationally predict reliability indexes of them in a more comprehensive and accurate way, eliminate the design and manufacturing defects and improve their reliability.
