Re: repairing broken traces on a PCB

I have broken traces on a PCB I recently etched. Just a handful ...

I am wondering how some of you repair them. Trying to tap into your body
of experience with this.

I tried soldering wirewrap from one trace to another ... but thats not
very effective ... I might try pin to pin this weekend.

ALso I have seen (on some pcbs from commercial equiptment) special
round shaped adhesive tape that placed on the strip repair wire to hold
it to the board.

Anyone know what these are called and where I can get some?


Rather than scratching about traces trying to make them solder-able, we
always go from pad to pad with wirewrap wire, complete with insulation. Good
quality cutters, fine iron tip, steady hand, followed up by some adhesive to
keep the wire in place (following over the trace that was damaged) and then
covered with a spray-on conformal coating.

Cheers.
