Microscopy Study of Tin Whiskers

摘要

Tin whiskers are electrically conductive crystalline structures that may spontaneously grow from pure tin-plated surfaces. Since pure tin-plating is used as an electronic component lead finish, there is an inherent possibility that a short circuit may be formed between the component’s leads by tin whisker growth. The focus of this article is to share tin whisker observations that the authors have encountered over years of tin whisker research.
