Probably will. What is standard in the industry are rub-on copper-foil traces. You clean part of the trace a couple of mm back from the damaged area, select the right shape "sticker" from the repair kit, place it where the missing edge connector pad is, rub the front of the repair kit to bond the replacement pad to the fiberglass, then (I think) add a touch of solder where the old trace and the new trace overlap. It's easy to draw; it's hard to describe verbally. Imagine the same sort of dry-transfer pad that are used for building a PCB manually on blank copper-clad board, but instead of etch resist, the shapes are made of copper and meant to be soldered to, once applied. I have never used them, but I know they are still available, even for SMT pads (which lift off very easily from too much heat during rework). -ethan -- Visit "The Seventh Continent" http://penguincentral.com/penguincentral.html Message was sent through the cbm-hackers mailing list
