I used to work in a test house. One of the testers was a
Schlumberger S90 memory tester. The test head contained
several boards in parallel, very close together. The
boards had several tantalum capacitors. Once one of the
tantalum capacitors blew a hole in the board about 1"
around, smallers holes on the boards to each side, and
badly melted areas on the next board on each side, for
a total of five destroyed boards. These boards weren't
cheap, but we had a maintenance contract, so we didn't
have to pay for them.
