Electrolytic broth
« on: September 03, 2016, 05:40:05 pm »
Yesterday , i was searched a capacitor on a lunchbox  where i keep all huge capacitor from old PCB  scraping.

 I found almost all capacitor coated with a sticky liquid that i think that is electrolytic

Today , i decided to clean and testing  the capacitors   and  i found  7 suspects and 5 deads(without external evidence).

Of the suspects,  i have seen that practically there aren't nothing ,only i can see a few very small drops on the  bottom capacitors  that i don't know  if is a leakage or a dry electrolytic.

But the more strange is that the lunchbox was quite dirty of electrolytic.

Where has it gone out so much electrolytic ,when i haven't found any hole or slice  on  the capacitors ? :-//

The capacitors were most likely leaking from the bottom bung used to seal the bottom of the capacitors. I've seen this in a few bad power supplies I've repaired. Some of the cheaper capactors use a natural rubber rather than a synthetic one that can shrink over time and lose a good seal. The shrinkage of the rubber probably wouldn't be too obvious other than leaking electrolyte

My guess anyways
