While I wholeheartedly agree with the tool advice and the trick, I lifted a
bunch of traces on a PDP8a CPU board doing this. I don't know if it was
the particular board or generally crappy manufacturing at issue here. All
the HP test equipment I've fixed, most if not all from 1985+-7, survived
worse punishment.
I've also started reflowing and adding fresh solder before attempting to
desolder. Could be better heat transfer, or just easier to suck up a
larger blob.
