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 ?
