摘要
针对表贴电阻典型的失效模式,选取了几个案例进行分析,通过磨抛制样,X射线检查,扫描电镜及能谱分析等手段,对各种失效模式,阐述了其失效机理,并有针对性提出了控制失效发生的具体措施。
In view of common failure mode of surface mounting resistor,several typical FA cases are analyzed.Using the method of polishing and grinding to the samples,X-ray inspection,SEM observation and EDX analysis,the failure mechanism is elaborated for different failure mode of surface mounting resistor.On the basis of the analysis,the control measures to prevent occurrence of failure are proposed.
