Title: Keychron Q6 broken trace
Post by: onelivesleft on Mon, 13 February 2023, 13:45:17

Just got a Keychron Q6, but the "A" key doesn't work, I'm assuming because of a broken trace on the PCB. Does anyone know which key I should solder a connection to from it to get it working again? (Keychron are sending me a replacement PCB, but I'd like to fix it if I can)

Opening it up to investigate I find what the actual problem is:

This diode has broken off.  Guessing that's not really something I can repair?

That should be quite easy if you are know how to solder and have a soldering iron a some diode, just solder a diode between the start and finish of this trace. I bet the start is the hot swap socket plate that is just on the upper part, for a the end just search a solderable part that is connected to the other end. Even soldering to the copper exposed part of the broken diode should do the trick (the copper on the bottom part).
If you haven't any, use 1N4148 diodes.

Thanks! I'll give it a go.
