I think I would promptly retire that PCB... it rather reminds me of one tha=
t the factory manager had where I worked, from a car radio that fell into t=
he flow solder bath - came out fully encapsulated. I don't know how they go=
t it out, presumably they emptied the bath periodically.

Or not as the case may be. A colleague was very lucky not lose an eye due t=
o a reverse tantalum. We had a printer arrive from our supplier, but it wou=
ldn't work. Said colleague pulled the back off and was eyeballing the PCB w=
ith it powered up, leaning over the bench so he could look inside the chass=
is containing the PCB. A few seconds later there was this bang and the body=
 of a teardrop tantalum went past his ear. The unit had worked long enough =
to get past factory test, but the resultant rest period during shipping had=
 allowed the tantalum to go real bad after its initial mistreatment.
