I have personlally removed whiskers from tin plated metal pots on Basler
power supply regulators that were upwards of 3/8" in length and about 30
or 32 ga in diameter, more than enough to carry a sizable current. I had
another board that had a hole in it from a short, suspected a whisker
but the proof had poofed, although the pots looked like they had mold
growing on them.   The boards were 35 or so years old.

The report claims that Tim Whiskers can be up to 9mm long and carry 10mA
of current...
That's quite a bit of amperage for a 1-2 micron whisker, I didn't know
they were that hearty.

Subject: [TN] New report finds tin whiskers to blame in Toyota UA

A new report is blasting the NASA and NHTSA reports on unintended
acceleration in Toyota vehicles, and specifically says tin whiskers is
among the culprits.
