The weld spots on the backing plate are recessed so that the bit won't skid around as you drill. There will be an ever-so-slight lifting of the metal as you get through it so you can separate the aluminum face from the metal back. The mylar trace panel has holes where the weld recesses are, so you'll not be drilling through any of the circuitry. The BIG problem appears to be that the top and bottom mylar elements with the traces are fused together so that getting to the damaged areas to redraw the circuitry is nearly impossible. I'm going to get my hands on a few more dead keyboards and keep at it until I figure out. Deb.

Time for one of those ugly "McDonald's-cash-register" plastic keyboard covers! But the real issue is disassembly isn't it? Circuit traces can be repaired with a circuit writing pen that writes in a conductive polymer, sometimes you have to gently scrape the plastic to expose a good trace then draw the rest to connect over the damaged area, at least that's was up until the G5 keyboard, after that, I don't know how to get past all those spot welds that hold the keyboard film in place?

My keyboard is broken after some drops of coffee - big drops of coffee. After that left control and second row with numbers don't responding. Can you help me with finding traces of this keys? Thanks.

Do you think that would clean? Hey did you try soaking the keyboard in water as you said you would? Do you think that would clean?
