20-07-12 Keyboard adapter soldering jig1522 viewsTo solder up the keyswitch adapters, I used an old piece of scrap experimenter board with a female 40pin connector mounted.
This makes it very easy to keep the pins perfectly straight whilst soldering the tiny board.
TIP: Solder one leg, then with a small screwdriver, press directly between the two pins while re-flowing the solder on the first leg. The tiny board will then be sitting flush on the header. Solder the second pin, wait 5 seconds, then remove :o)
