Tin whiskers were a big deal around 2005-2012 or so, and then the
discussions suddenly dropped off. I'm not sure why.
I remember the story well. All the denials from the Toyota people and
then this story about the whiskers in the controls. ugh.
Here's a pretty good paper from about 2011 from Maxim that discusses the
issue:

It includes a bit on the danger (or lack thereof) of using lead-based
solders in electronics. Quite frankly, I wonder why the RoHS people
didn't mandate that lead flashing on roofs, lead canes in stained-glass
windows and a host of other applications weren't banned.
Not to mention lead in automobile weight balancers which is apparently
banned in Europe. I guess it's because roofs, lead canes in stainless windows
aren't recycled as quickly as electronics. I dearly wish they had have
mandated proper lead recycling instead of an outright ban.
