From the Radio Forum:
I remember one night long ago, the half-sleeping changed the 55th port in the 40-foot DIP.
The legs were bitten, the conclusions were washed out, he sat down with a sharpened light bulb / there was no toothbrush then / "perforated" the holes on the plate under the new micra.
Thus e. The fireplace was ticked in the place of soldering, and the solder on the other side heated.. so that the holes were made.

And at some point, instead of the lightning "blow up" the solder.. Woke up immediately.. :)))"
