Attached pictures are a lifted power pad+trace of a 1000W PSU of a commercial subwoofer. Caliper showed 0.42mm thick, which if correct gives about 12oz copper trace!
In this particular pad was the source of a mosfet after rectifier bridge, transformer and capacitors bank.
Pad+trace are intact, I just need to reliably fix them back to place.
What are the best options? Epoxy? Maybe araldite? I am not sure if it will ever corrode copper or sensitive electronics.
