Removed a few 'centers' of pcb through holes on V60 MTS, help?
« on: Sun, 17 January 2016, 21:59:36 »
I am swapping SKCL Green Alps switches into my V60 MTS and while de soldering a few centers/hole plating of the PCB holes came out with the old Matias switches.

Example:


I followed this thread http://deskthority.net/keyboards-f2/fixing-lifted-pads-kbp-v60-mts-t12179.html on deskthroity for lifted pads on a MTS, hand wiring to the SMT diode or to another switch leg that connected to the original, but I cant get the 3-4 switches to register. I cleaned the surface before doing so as well.

What can I do?
Thanks.

You're going to have to show the PCB and where the traces go. Depending on the pin, it changes how and where you have to jump the wires.

Here is what the PCB looks like


I am following the traces, for example on the [ key, the right hole connects to the bottom of the corresponding diode. For the left hole of the [ key I am not sure, it looks like it doesn't connect to anything.

Other keys like the ] key, the left hole has a visible trace.

Update

By looking at a picture of the front of the PCB I was able to wire the left leg and make a switch work!

This also means that my LED backlighting didnt work, since I fixed the key that turns on the backlight in the MX version at least. Likey using the wrong resistors.
