foam pads. was: Successful keyboard jack repair

Hello Clinton,

I suspect that the thickness of the foam is not right and the foil is not touching the pcb. I've measured a still functional pad and it is 3.8mm heigh, 11mm wide. at the moment I am developing a production methode to fix our more that 10 keytronic keyboards (lisa, vt100, gigi, etc.) and yesterday I combined a Ikea mousepad, doublesided foam tape and the bag from potato-chips. I still have to check if the foil is right for the job, but the height is critical.
