IBM had this problem back in the 70s with the silver plated tracks on

the backplanes of their mainframes. Fujitsu also had it with tin
whiskers growing on the connectors of their early sealed disk units in
the early 80s. They had to make a special zapper that burnt the whiskers
out.

25 years ago I had the job of wandering the distribution frames of
the (then) Telecom DDN with a stiff bristled brush to get rid of Zinc
Wnhiskers that grew between the pair legs.

It's a common problem.
