had one short (tant)
was specified by the datasheet on the very pricy A/D chip so I did exactly
what they said
didn't hurt the chip but I had nfi where the short was (4 people inspected
the board (verroboard/stripboard)) eventually it came to the "Australian
short circuit detector"
IE a 12V SLA battery, took all the bits off that came off easily and
connected the battery to
logic power rail. Thankfully one of the guys advised me to "aim away from
face".
I now have 5 or so big holes burnt into my desk where the glowing remains of
the tant wound up.
basically it cooked off with a similar force to a small "bunger" fire
cracker.
