Re: Circuit Board Arc Track Repair

I have a 55 year old door chime clock and the board has carbon arcs which is causing a short. I have seen boards with this problem before and they were repaired using some type of filler. What is used?
Depends on the board type, if it's paxolin or some kind of resin bonded paper then just scrap/grind out the carbonised parts (dremel with a burr is ideal) then fill with the epoxy of your choice unless you're happy to leave it as is. The only problem with not filling is you may increase the moisture absorption of the board by exposing the edges, making further damage more likely, conformal coating would help.

Thank you for your help
