My first post here in this fascinating group :)
The trick I use for repairing the finest of damaged traces, involves
using conductive paint.
This is usually quite expensive to purhase as a generic product
through electronics outlets, but can be obtained from most car
parts shops as 'windscreen/windshield heater repair paint'.
Acurately position 2 lengths of low-tack MASKING tape, either side of
the broken track. Press in place firmly. Using a small fine brush,
paint over the broken track (don't 'blob' the paint - thinner is
better). It dries very quickly, so you can remove the tape after only
a minute.
Masking tape is preferable to clear sellotape, as it absorbs all of
the excess paint and prevents any 'fringing' at the edges.
Having a very low resistance of typically <0.1 ohm / inch, it will
carry heavy currents and makes a excellent permanant repair !
