Research on Lead-free Bonding Technology by Hand
Author(s): 
Pages: 79-81
Year: Issue:  2
Journal: Electronics Process Technology

Keyword:  Lead-freeBonding TechnologyShearing;
Abstract: 介绍了无铅化推广以来无铅工艺研究的紧迫性;开展了多种封装阻容器件的焊接实验工作;通过对焊点剪切力性能的对比和分析,总结了焊接时间对于焊点改善焊接质量的作用;通过观察不良焊点的剪切力试验断面图和微观视图,阐述了焊接时间对于改善焊点质量的原因;发现在本实验条件下,适当延长手工焊接时间,有助于改善焊点质量。
