Environment banned the use of lead based solders, the new tin alloys grow whiskers that eventually short circuit other components rendering the device useless.

NASA has a website dedicated to the topic, many photo's.

Tin is not the only metal known to grow whiskers.

Now this got me thinking of the voyager satellites NASA sent out in the 70's. probably all lead solder used on that considering its going out to space and not ganna be an environmental concern. crazy how that thing is still going.

Lead does not grow whiskers, capacitors also age out. Caps usually have a 10 year life span, people that purchase old transistor radios and stereo equipment replace every cap which usually brings the unit back to life.
