View Full Version : Motherboard trace repair?
06-14-04, 11:03 PM
Are there any options to try and repair a scratch in a motherbaord pcb?
I aparently banged somethign into the backside of my IC7 Max 3, there is a clearly visible scratch in the pcb and a bit of copper color peeking through. Does that mean there is damage to the underlying layer? If so, can it be repaired?
I know you can reattach traces with some careful sodering, so is it feasable to try a repair or should i bite the loss and take it like a man?

Does it work fine as it is? it's possible it'll work fine.
If it doesn't boot, then might as well give it a shot.
personally for thing like this, I just lay the wire across it and superglue it. I'm bad at soldering though, so that might be why.

try scraping off the top layer of protective coating off to expose the scratched copper.... solder it and then when the connection is made, test it. when it works, spray some Krylon fixative, the kind you use for art, and fixing charcoal. It makes a nice protective layer on it again... shiny too... I've done this b4

Scrape off the solder-resist layer on the top like newbienerd said and use a very fine gauge wire to bridge the scratch. The dent shouldn't have gone through to the next layer unless there is a really big gouge there.

Instead of solder try using a rear window defogger repair fluid to fix it. That way you don't have the chance of burning the board and screwing it up worse. You can find it in most auto parts stores, usually around the "loc-tite" type stuff.
