Suggestions for which or what supplies I need for PCB trace repair?

[ENS Audio]

I need to repair some PCBs and so not only was I looking to fix the lifted tracks and some tracks that completely broke off.

I know theres a few things such as:

strong adhesive

varnish ( for compensating for soldermask )

solder pins (what type for wire wrapping )

bus cable

also would turrets be recommended instead of solder pins???


Urgent help is needed!!! ;D

Thanks,

Resistor legs.

Operate the same way dental technicians do: You get your
needle nose pliers and bend one into exactly
the shape of where the trace was, then tin
the ends, tin the traces, and solder them together,
holding one end down first and then the other.

I once had to repair a control board PCB that had been completely split to two pieces (a punch on a synth control panel, or a dropped instrument, who knows).

The best thing to do was to point to point wire the traces between the two pieces. Just find the nearest hole from the point of split (usually a resistor) and wire from there.

Hey, it's now more flexible (physically I mean) than the original ever was, and will withstand even harder punches!  ;D

The easiest is to use the "cutoff" resistor and cap leads and bridge the lited traces with that - or even wrap around some to tighten things up.

IMO the best way is Kynar type wire wrap wire. This is small gauge (usually #28 or 30) solid wire that is easy to form and bend, with insulation that won't melt. Completely remove the old foil trace, clean off the flux residue, and jumper around it with a short length of wire, putting a little bend in the jumper wire so that it is not taut. For a finishing touch you might tack it down with a small drop of hot glue. This will result in a very neat repair with a factory appearance.
