摘要
本文通过对波峰焊和热风整平（HASL）工艺锡槽中铜含量升高所导致的产品最终焊接不良问题原因的探讨，分析了铜含量升高所带来的危害及其常用的降铜处理方法。
This article through discuss the reason for the problem that the product eventually welding bad that caused by copper content rise wave soldering and hot air solder leveling （HASL）, then analyses harm of copper content rising brings and common used method to deal with it.
