摘要
在分析常规可靠性评价方法存在问题的基础上 ,介绍目前国际上广泛采用的元器件内在质量评价技术和具体要求。整机生产厂可借鉴此技术 ,考虑采用进一步保证元器件质量和可靠性的有效方法。元器件生产厂家也可以根据评价要求 ,考虑如何改进产品设计和工艺控制 ,与国际要求接轨 ,尽早将产品打入国际市场。
Based on analyzing the shortcomings of the traditional methods for evaluating the quality and reliability of electronic parts,a new technique is introduced This new technique focuses on evaluating the building in quality of electronic parts using the following three parameters:C pk (Process capability ratio),SPC(Statistical Process Control),and PPM(Parts Per Million),and is widely used by many famous international companies The electronic parts users could select the high quality parts with this technique,and the electronic parts manufacturers could improve the quality of their products according to the evaluating requirements
