资料介绍

连接器焊接不良失效时有发生,针对连接器引脚空焊不良进行了深入的分析,详细地介绍了分析的过程和手段。通过外观检查、wetting balance、切片、SEM+EDS、DSC等分析手段,发现连接器引脚空焊不良的主要原因是FPC$欠板变形。同时,提出了有效的改善对策,以降低或避免此空焊不良的发生。

Poor welding failure of connector occurs from time to time. The poor air-welding of connector pin is analyzed deeply, and the process and means of analysis are introduced in detail. Through the analysis means of appearance inspection, wetting balance, slice, SEM and DSC, it is found that the main reason for the poor welding of connector pin is the deformation of FPC. At the same time,some effective countermeasures are put forward so as to reduce or avoid the occurrence of poor air welding.
