Some may argue that tin pest is not much of a concern for lead-free soldering since most electrical devices would not see such low temperatures. However, automobile electronics and cellular phone base stations could succumb to the effect. In light of this concern, this paper will review what is known about tin pest, suggest how this information affects the lead-free assembly industry and recommend future work to clarify any remaining concerns.
Key words: Tin Pest, lead-free solder, and tin whiskers.
