There was a rash of bad capacitors coming out of Asia roughly between 2002
and 2006. The story I heard was one manufacturer made a change to save
money, and through industrial espionage, several other companies also made
the change in their electrolytic formula. In the following 4 or 5 years, cap
failure was a common thing. Even in older electronics, capacitors
have been known to dry up over time. Many older Mac models have leaky
capacitors, and if they are not replaced or cleaned up, the chemical could
destroy the traces on the boards, making them un restorable.
