摘　　要：印制电路板板边插头压接操作会产生相对摩擦,这对耐插拔能力和导电性能要求高,通常采用镀金表面处理工艺。引线作为板边插头镀金工艺的导电通路,在完成镀金后需剔除,以免造成短路问题。目前,手工剥离、蚀刻和钻孔是剔除板边插头引线的常用方法,均各有优、缺点。对上述3种剔除工艺展开试验分析,探究优化引线设计和制作工艺的方向,解决手工剥离和蚀刻工艺易产生引线残留、钻孔工艺易出现钻偏和披锋等问题,为板边插头引线加工制作提供参考。Printed circuit board edge plug crimping operation will produce relative friction,high requirements on plug resistance and conductive performance.Gold plating surface treatment process is usually adopted.The lead,as the conductive path of the edge plug gold plating process,needs to be removed after gold plating to avoid short-circuit problems.At present,manual stripping,etching and drilling are common methods for removing edge plug leads,and they all have advantages and disadvantages.This paper explores the direction of optimizing the lead design and production process through the test analysis of these three kinds of removal processes,and solves the problems of manual stripping and etching processes that are prone to lead residue,the problems of drilling process that are prone to drilling deviation and skew,etc.,so as to provide references for the processing and production of edge plug leads.
