I have a couple of model 01 keyboards, one of which has a faulty switch. This time around, I elected for Keyboardio to send me a replacement switch and to try the repair myself; I can solder enough to complete a partial keyboard kit by soldering my own switches, so I hoped that’d be enough to see me through the repair.
Unfortunately, I’ve run into trouble desoldering the current switch, and I understand that it’s important to do this cleanly so I don’t damage the contacts on the board when trying to remove the switch.
After multiple attempts applying the iron to the join to melt the solder, I still can’t remove it with the desoldering pump; even if the solder looks like it’s melted again. I’ve tried a range of temperature settings (up to 480ºc, from memory?) without luck. I’m assuming the issue is that I haven’t sufficiently melted the solder in the hole, but I’m wary of damaging the board with high temperatures.
Any advice from anyone who’s replaced a switch without breaking their keyboard? Has anyone written up a guide to this anywhere?
