    I have an Asus A8n SLI Deluxe. The chipset fan went bad so I had to change it. While taking out the old one I slipped off the peg and put a ding in the bottom of the mobo. :eek: It's not a major dig, but you can see copper if you look hard. I'd heard somewhere that you can cover something like this with nail polish... or did I just ruin the board?

    Before I put the thing back together does anyone have any experience with this?

    Thanks for the quick reply, StumpedTechy. I take it as a good sign that you didn't just tell me to throw it away...

    No need to throw away somethign that works... if it doesn't work and the traces are broke you probably will want to though unless you know someone who works on PCB's and can solder.

    I've done this before with nail polish, it works fine. Pretty much anything that can protect the tracing from corroding can be used.


    I use a conductive ink pen, bought from Radio Shack (approx $14), to rebuild broken traces on boards. In fact, I just fixed a broken Noritake 4X20 VFD last week with it. Soldering small traces on circuit boards is way to aggravating. The drawback to the conductive ink pens, is that you really have to shake them up before using them, and you may need several layers of "ink".

    One more thing if its a multilayer PCB these "fixes" won't work if you have damaged something on the inside layers....

    Just one last note to dash all your hopes of salvage :) just kidding of course hope it turns out well :)

    Motherboards have multiple "layers" of copper tracks within their thickness, there will be no way of knowing if an internal layer is damaged as you cannot see them all.

    If it works its OK, if it fails or is unreliable, you know why. Its only then that its consigned to the bin.

    Well, folks... thanks for all your replies... it's working! I don't know who designed that chipset fan, though... it's a piece of junk to start with, and the clips holding it in are enough to make a grown man cry!

    Thanks again!

    btw, used clear coat nail polish...
