When I worked for Texas Instruments in '83, we used 30ga 24K gold wire... I use plain wire-wrap wire for board repairs, and from the looks of most of my pre-1990 circuit boards, that's period correct. The only issue I'd have with that 3M tape would be cutting it narrow enough to fit.

Hi All, I'm going to be attempting to repair, both cosmetically and operationally, a circuit board that had a strip of 12 volt trace "blown off" of it by a short. The fiberglass is clean and there was no solder resist in the affected area. I'm considering using 3M 1183 adhesive tinned foil
