A friend and I recently acquired a Compaq Portable, and we need to fix the keyboard. Much like most gamepads, the PCB has split traces that are connected by a conductive pad under a button. In this case, each key has a foam pad underneath, and the pads have thin plastic underneath which were at one time painted silver. The silver paint has worn off of every key, and I'm trying to think of a good replacement contact. I've considered squares of aluminum foil, glued onto the existing pads, but I'm wondering if there's a better solution. Right now, we're using our fingers to touch the PCB and type, which probably isn't the best idea. Anyone have a better idea than the foil?
