焊接工艺不当导致元器件失效的原因分析

摘要

通过对典型案例的介绍，分析了焊接工艺不当对元器件失效产生的影响。通过对焊接工艺过程中各种影响因素的分析，以及对各种失效模式总结，阐述了焊接工艺不当(包括焊接前，元器件的预处理不当)，造成元器件失效的失效原因与机理，在此基础上，提出了有针对性的改进措施。%Through the introduction of typical FA cases, the influence of improper welding process to the components failure is analyzed. Through the analysis on the various influence factors during the welding process, and the summary of different failure modes, this paper expounds the failure reason and mechanism of electrical components affected by the improper welding process, and the improved methods is proposed.
