Tin Whiskers: PCB Soldering Issue | EAGLE | Blog

The cause? Tin whiskers. What Causes Tin Whiskers? Here’s the troubling part to stomach, we don’t know exactly what causes tin whiskers. There are a ton of theories out there, but all we really do know is that when lead isn’t used in electronics for plating and soldering, the risk for tin whiskers grows.

How and Why Tin Whisker Grow in Electronic components ...

Apr 04, 2019· The Tin Whisker is a conductive hairy-like crystalline structure of tin that grow spontaneously from a tinned surface, usually as a result of the stress of some sort, and maybe long enough to cause a big problem for those applications demanding a high level of reliability.. In this case tin (especially electroplated tin) is used as a final finish. Most usually tin-plated cop
