Zinc Whiskers

2002

Help on Zinc Whiskering required.

1. Is there a standard or preferred coating to prevent/reduce zinc whiskering occurring?

2. What finishes should NOT be used in computer underfloor installations in the prevention of zinc whiskers?

Zinc, like tin, forms whiskers when subjected to electromagnetic energy or electrical current. Alloying the zinc is the best way to prevent whiskering. There are several choices: Zinc-nickel (I think it is the best) Zinc-cobalt and zinc-iron.
