    Default Need help with damaged SMD pad on motherboard

    I have lifted a solder pad from a circuit board where a PLCC chip resides.
    I need advice on replacing/repairing missing pad(stupidity on my part and pad is gone)

    I've seen repair kits but $200+ is getting a bit pricey where I doubt if I would use more than a single solder pad.
    Any advice welcome.

    Thanks.

    There's a few products around that you can 'paint' tracks on boards.

    Plus others that are stencil type tracks, pads, etc.

    I've used this before to repair boards.

    Hi mtv,I got the conductive pen from Jaycar. It doesn't appear to conductive at all.Lots of silver goo coming out but when it dries it gets flaky to touch and very high resistance.
    What have I done wrong?

    Perhaps putting it on too thick?

    Are you heat-curing it?

    Apologies for not getting back,It's too hot to work.
    The instructions are quite nebulous. Heat cure with a 20W bulb.Incandescent I guess,how far away? Who knows.
    I made it as thin as I possible could and let it dry naturally in the shed.It's been hot out there when I attempted using it.
