Practically, I guess assume you hold the diode to the pin, solder it, bring the wire to the diode and solder it.
How do you hold the diode, the iron and the solder at the same time?
My guess is you pre tin the switch pin, get a blob of solder on your iron and have the diode in tweezers at the ready then put it all together. It only needs a small bead of solder (and flux).
Right! I can see how it would be fast then. “Just” tin all the pins, and when all the pins are tinned have your solder in a fixed position and then move your iron from solder to pin, stick the diode, and repeat.
Cool!
Is that using magnet wire to run the matrix? That small of guage seems like it will potentially break with some shock force (dropping a keyboard from a few centimeters on a wooden desk or something). Or is there a backplate supporting it?
yeah, they are quite delicate. I wanted to use thicker ones but it is hard to get thick magnet wires.
I never tried dropping them so idk, I guess making them less tensioned would help a bit
