failure analysis of electronic components

the introduction

the rapid development of electronic components and its reliability laid the foundation for modern electronic equipment industry, more attention should be paid to thereliability analysis works.by analyzing the failure mechanisms, finding out the failure causes, feeding back the conclusions, researching and carrying out the corrective actions, the reliability of electronic components can be improved.

the purposes of failure analysis for electronic components are to confirm the failure phenomenon, to distinguish the failure mode and failure mechanism, to find out the root cause, to make recommendations for improving the design and manufacturing process, to prevent failure recurring and finally to improve the reliability.
