本文对从1940年到现在美国环境试验和应力筛选的发展状况进行描述,并探讨了环境摸拟和环境激发的主要区别,这对于把环境应用于电子试验和应力筛选两个领域加以区分是很重要的.本文还讲述了环境模似,试验种类、寿命循环及试验剪裁方法,讲述了环境应力筛选及其可筛除因部件或工艺缺陷而产生的失效的作用.为提高产品质量和可靠性,为中国的电子产品打开国际市场,推荐了试验剪裁和确定有效筛选的方法.
This article describes the state of the art of environmental testing and stress screening in the United States from 1940 to the present and explores the major differences between environmental simulations and environmental stimuli that are important for differentiating the environment from electronic testing and stress screening Important.This paper also describes the environmental simulation, test types, life cycle and test methods, about the environmental stress screening and screening out the failure due to component or process defects in order to improve product quality and reliability , Opening up the international market for China’s electronic products, recommending tailoring and identifying effective screening methods.
