Abstract

The importance of soldering in the semiconductor industry continues to grow as packages become denser, with the resultant increasing number of connections between chip and substrate. During soldering, intermetallic formation at interfaces and/or in the bulk of the solder can affect physical properties of the joint. We have found that initial stages of wetting control intermetallic formation, its dispersion in the solder and the solder's wetting characteristics.

焊接中的初始润湿和反应顺序
随着封装变得更密集,芯片和衬底之间的连接数量随之增加,焊接在半导体行业中的重要性也在不断增长。在焊接过程中,界面和/或焊料中金属间的形成会影响接头的物理性能。我们发现润湿的初始阶段控制着金属间质的形成、在焊料中的分散和焊料的润湿特性。
