Capacitor Reliability Question
#5

Not exactly related, but a few years ago there was a LOT of "bad" capacitors on the market. Tons of computer equipment, mainly motherboards and power supplies, were affected.

The capacitors would become leaky quite fast (less than a year of usage) and you guess what that could do to computer motherboard.

I remember seeing some on ebay, people would buy them and recap them. With luck they'd end up good as new.


Modern manufacturing process doesn't believe in quality check. It is cheaper to have to refund the few who cares complaining than having to ensure everything that goes out the doors is valid. Moreso in some asian manufacturing plants.

I think it all started when then invented this motto "no user serviceable parts inside" and started to add "warranty void if seal broken" stickers.
