1 失效分析工作的重要性及工作内容 失效分析是通过对失效器件的理化试验分析和理论分析找出失效机理，提出减少或消除与失效机理相关失效模式的全过程。 要提高产品的可靠性，必须在产品研制阶段有严密、合理的可靠性设计，必须进行产品可靠性评审；在生产阶段要有严格的工艺
The importance of a failure analysis and job content Failure analysis is to find out the failure mechanism through the physical and chemical test analysis and theoretical analysis of the failed device and put forward the whole process of reducing or eliminating the failure mode related to the failure mechanism. To improve the reliability of the product, it must be in the product development phase has a rigorous and reasonable reliability design, product reliability assessment must be carried out; in the production phase to have strict process
