 Tin Whiskers
Tin whiskers are electrically conductive, crystalline structures of tin that sometimes grow from
surfaces where tin (especially electroplated tin) is used as a final finish.
Tin whiskers have been observed to grow to lengths of several millimeters (mm) and in rare instances
to lengths up to 10 mm. Numerous electronic system failures have been attributed to short circuits
caused by tin whiskers that bridge closely-spaced circuit elements maintained at different
electrical potentials.
