If the hole is big enough, stick a tiny wire thru for the

a strand from a stranded wire can work.

I just repaired a Snap-On Modis OBDII scanner in this manner. This
is a multi-layer board, but fortunately the liquid damage was limited
to a top to bottom connection, not an internal one.

Years ago I was given a roll of transformer wire, which is very thin
and lacquer coated. This will snake into very small plated through
holes and it did perfectly in the scanner. If the scanner were a
double layer board, it would have been simple enough to drill a small
hole next to the dead feed through, but on a multi layer, that's out
of the question. Transformer wire is ideal for pushing through a
blackened feed through. Single strands from stranded wire is
certainly thin enough, but it won't have the stiffness to push
through most plated through holes.

I decided to take some fine gauge wires and run them around the side of the
board to get to the other side. It wasn't the most elegant fix but it
corrected the problem.

Thanks for your reply.
