In practice these soldering joints aren’t quite so magical, but they are pretty darn close. I’ve run into problems with the big sizes (10-12 AWG) and the smallest sizes (24-26 AWG).

I now have a pre-heater and hot air, and if there are connectors on the pcb I can use low melt solder (4.50 euros for 17cm wire) or heat the pcb from the bottom, which may result in burn marks.

With self-fluxing wire and a dispenser pen you can wire all the nets then solder only the bits than need to conduct. Report comment. Reply. pac says: March 10, 2020 at 8:23 am ...
