摘要
无铅化电子组装中,由于原材料的变化带来了一系列工艺的变化,随之产生许多新的焊接缺陷。本文针对“晶须”现象、离子迁移和元素污染三种缺陷进行了产生机理分析,并给出了相应的解决措施。
Changes of material bring a series of process problems in lead-free electronic assembly with occurrence of new solder defects. This paper analyzes causes and gives solution of solder defects for whisker, ion migration and element contamination.
