Mechanical bend and shock tests are routinely performed on SMT assemblies to ensure that they can sustain anticipated production, handling and end use conditions. The strains and strain rates applied to SMT assemblies during bend and shock testing can lead to a variety of failure modes in the vicinity of the solder joints. This document provides test methods to evaluate the susceptibility of...

简要介绍 (英文) 对SMT组件定期进行机械弯曲和冲击测试,以确保它们能够承受预期的生产、搬运和最终使用条件。在弯曲和冲击测试过程中,加载于SMT组件的应变和应变率在焊点附近会导致各种失效模式。本文件提供了测试方法去评估印制板组装(PBA)材料的敏感性和关于表面贴装技术(SMT)的连接焊盘下方绝缘材料接合失效的设计。这些测试方法,包括引脚拉拔、焊球拉拔、焊球剪切测试,可以对不同的印制板的材料和设计参数进行排序和比较。全文共17页。2010年12月发布。2013年5月翻译。
