元器件生产商试验数据研究及其在卡件可靠性预计中的应用

Component Vendors' Testing Data and it's Applications in Reliability Prediction

目前常用的可靠性预计标准所提供的元器件模型和数据在发挥其作用的同时,存在着针对性较差、实时性较差和重要统计学信息缺失等局限性。随着可靠性试验技术和数理统计技术的广泛应用,越来越多的元器件生产商通过其网站等渠道发布了其产品基于大量样本的试验数据。基于对预计标准中模型和数据局限性的分析,重点对生产商试验数据的数理统计等方法进行了研究和介绍,并从检索便利程度和数据质量等角度对部分具有代表性生产商网站公开数据进行了调研和评价,最后对这些试验数据在卡件可靠性预计等工作中的实际工程应用进行了讨论并给出了建议和结论。

Strategy and data resources of various prediction standards are firstly investigated.Their limitations were summarized.Concentrated analyses are further conducted on a representative published reliability testing results,calculated failure rate and the corresponding statistical theories.A survey and evaluation are also shown based on the ease of searching and quality of testing data in various typical vendor＇s websites.Finally,suggestions during practical engineering application of these reliability testing data are discussed and concluded.
