    Hypothetical damaged motherboard question

    Imagine that someone had damaged a motherboard whilst unclipping a Socket A processor and a screwdriver had slammed into the board severing three tiny tracks on the PCB leading from the DIMM slots. Each time they powered up the system, all they got was a series of long beeps indicative of a DRAM failure, yet the sticks test OK in another system. In fact, let's also say that this system had been working barely fifteen minutes before, albeit out of it's case..

    Now imagine that because this was a junk board anyway, someone wanted to try 'bodging' a repair in some way.

    How might they go about doing it? Hypothetically I mean.

    Re: Hypothetical damaged motherboard question

    Well this person might kinda sorta wanna get some .022 or smaller Silver solder, an extreemly fine tipped soldering iron, Maybe possibly after taking 100% Isopropyl Alcohol on a foam tip Q-tip and carefully cleaning the area and then giving ample time to dry, say a hour of so, that poor imaginary person can possibly connect one piecs of solder and "jump" it over the fictional gap. All part available at Radio Shack for less than a new Mainboard. This person we will call Nobody, he or she should be aware that motherboard manufacturers sometimes put a coat of stuff (the technical term used in purchasing { Yeah Fred, we need 55 more gallons of Stuff}) over the board so there will be a brown "meltaway". If Nobody does not get the board too hot the jumper should work. The solder does not have to touch the board like a trace, it just must connect the gap between the two tracts. If Nobody lives near a PCB plant like Lucent Tech they might go and make a friend by bringing <img src=/S/money.gif border=0 alt=money width=17 height=15> and seeing if their line has someone on break where the expensive high tech equipment is use, theoretically that is.

    Re: Hypothetical damaged motherboard question

    Just further to Kent's reply - you may also find that tiny little wire jumpers - also available at Radio Shack et al - can be used as jumpers in lieu of recreating the severed traces. If the coating of "stuff" <img src=/S/laugh.gif border=0 alt=laugh width=15 height=15> on the mainboard has been damaged, there is a possibility that the solder will merge all three of the conductor traces together with hairline connections - just like water flowing in a streambed.

    Interesting idea, Kent. I'll remember this advice, just in case I ever meet anyone unfortunate enough to have made such a clumsy error. <img src=/S/innocent.gif border=0 alt=innocent width=20 height=20>

    Re: Hypothetical damaged motherboard question

    Also, that person might try some stuff called "circuit trace", I think it is anyway. It's a semi liquid high silver content, material that you just apply like a pen point to the clipped traces. It leaves a tiny line of conductive "trace" to repair the board. I have used it quite a few times and was successful in making the repair every time. You DO have to be very careful( with a good steady hand) in drawing the new trace, avoiding any overlap to an adjacent foil line.
    I think it is still available at MCM Electronics (mcm.com) BTW, this is GOOD source of electronic goodies and I use this much more than Radio Shack or other places like that.
    I hope that person has better luck in the future! <img src=/S/crossfingers.gif border=0 alt=crossfingers width=17 height=16>

    Might also be good to dope the connections once they have been verified to be working.

    That's right. Any way to reinforce the damage site is fine.

    Would candle wax dripped onto the injury site do the same thing?

    Probably - but could be messy. Nail varnish would do the job.

    Re: Hypothetical damaged motherboard question

    Anyway, to conclude this, a helpful friend who works in electronics took it to his workplace and asked one of the kind technicians to see what she could do. I got it back yesterday, reinstalled the CPU/RAM, powered up and.........it worked!
