I'm not too proud of my first ever attempt to repair a trace with magnet wire, but that thing is *tiny* and even with magnifying glasses I had a hard time seeing what I was doing.
The disaster are is a corroded ground pin. It looks bad, but it will hold just fine for now.
More worryingly, several vias look badly corroded, but I have no idea how to reconstruct them. I can't simply suck the dark goo from the hole, so perhaps I should drill through?
