一、问题的提出用“高效应力筛选法”提高电子产品的可靠性,近几年来在国外被迅速而广泛地推广。美国海军更于1979年春颁发了《海军电子产品应力筛选大纲-NAVMAT P-9492》(已译。由《强度与环境》编辑部编辑出版)作为海军电子产品生产中对元件和工艺两方面缺陷进行筛选的指导性文件。实践证明,按一定技术条件进行的应力筛选,确实获得了高可靠的电子产品,所以被视为提高电子产品可靠性的“法宝”。最近国内也已注意这一技术,一些单位试用高效应力筛选法,
First, the question put forward “Efficient stress screening method” to improve the reliability of electronic products in foreign countries in recent years has been rapidly and widely promoted. In the spring of 1979, the United States Navy also issued “Naval Electronics Stress Screening Program - NAVATAT P-9492” (edited and published by the editors of “Intensity and Environment”) as a defect in the production of navy electronics for both components and processes Screening guidelines. Practice has proved that, according to a certain technical conditions for stress screening, did get highly reliable electronic products, it is considered to improve the reliability of electronic products, “magic.” Recently, this technology has also been paid attention to in China. Some units try the effective stress screening method,
