@steter For today, I was mounting some 3.5mm sockets in strip board. Nothing fancy. Basically making some MIDI TRS AxB changers. It's just the holes are 1.0mm and so are the pins... I need to find a 1.2mm drill bit, but I made do with 1.5mm today.
I did, of course, check my soldering afterwards with a loupe, and did continuity checks, too.
