@quadcells, if you can see the damage and it is localised, and you have a fine-tipped soldering iron, it might be possible to repair it by soldering a single strand from some stranded wire over the break. The traces are only 0.15mm wide, OTOH I've hand-soldered 0201 SMD components (0.25 mm × 0.125 mm) before now.
It would probably be OK to paint some polyurethane varnish or similar on to the PCB to help protect the traces in future.
