Hello I attempted for the first time to desolder and attach some new switches. Things did not go well… I thought a fix would be to follow this guide: https://www.instructables.com/How-to-Rep… Upon completion there was still no contact with both M1&M2; here are the photos after I cleaned up.
In the first photo as you can see I attempted to cut the excess copper before solder, not sure which method would have worked better considering the copper adhesive would move even after being heated which was expected. My primary questions I suppose would be in photo 1 am I suppose to match the adhesive exactly to size or can I have some excess laying on the PCB? Am I also to clean more thoroughly? I used 97% isopropyl with electronic swabs. The soldering wire has flux so I didn’t apply any flux paste which came with my kit. In photo 2 am In trouble with the trace? I should also ask if my method would even work using 5mm copper adhesive. P.S. I can make an additional thread for this but I tried the same method as well on my Celeritas keyboard
and had no function with the switch I used? What’s the deal? Thanks for reading and any help!
Hi @kembaw , To me the problem is how to mount the switch so that it remains secure and doesn’t come loose rather than how to electrically connect it to the circuit board. I would try gluing it to the board (neutral cure silicone sealer perhaps) and hopefully there is enough excess connection tails from the switch showing through on the solder side so that you can run insulated wires from them to where the pads that they should’ve connected to first make contact with another component and solder the insulated wire to that point i.e. bypass the faulty pad and track so that the switch is wired directly to the next point. Here’s an image showing what I mean from the last image that you posted.
