Bios Chip Replacement

Anyboby got an idea what is the best stuff to use to reinstall a bios chip that was originally "soldered"or otherwise glued in?
I have a new upgraded chip and was thinking about conductive epoxy(it will be the last one for THIS board if I do). HP didn't want you to change it to the mobo manuf. chip which I have both chips. Not knowing,I got under it with my fingernail and it popped out with no apparent damage.Then I saw it was not suppose to be replaceable.DAAAAAAA



THANKS, for any and all help.

    Lay it in place, assuming all the connections are still made, and then tape it down w/ electrical tape. :) I just can't imagine being able to solder a chip back on any recent mobos. Old mobos had small solder points, but the stuff nowadays is just so tiny that it's nearly impossible for a human to solder.

    if your good at soldering, its solderable.

    see thread below for how i did one on a compaq board.

    I am wanting to know about conductive epoxies or somthing like that not soldering.I want to glue it on!!

    the chances of glue'in that thing on without bridging two pins is small. and depending on the cure rate for that stuff, your gonna have a hard time getting the proper amount on all 32 pads before the first ones start to harden. its gonna take time and alot of precision, cause not enough and it wont bond, and too much will ooze and bridge the next pin.

    least with soldering, you can easily go back and unbridge adjacent pins if you bridge them.

    just glue (or epoxy) the center of the chip to the board.

    Why would you want to glue it in anyways?

    Because it was originally soldered and with my "STEADY"hand and no equipment that small. I thought it would beat no chip.
    What twitch,they don't call me "nerve's" for nothing.

    So your saying you soldered it in yourself before, or it was originally soldered by HP?

    Either way, who cares? It's not going to come out unless you yank on it.

    Then epoxy the center of the chip to the board, or duct-tape the damn thing on.

    Seriously, soldering the chip back on is a stupid thing to do, unless you have a wave-solderer. The heat from the iron alone will kill the chip.

    Otherwise, save yourself the time and smack it with a large brick. :rolleyes:

    The original question was ---what other than solder is good for re attaching this chip---you did not read all of the above. I have said nothing about trying to resolder it.Conductive epoxy will do the job as good as solder but I was wondering what else would.
    What do you think will happen to the glue on tape when it gets hot? I want to FIX this not shade tree it with a patch!!!!
    In case you havent heard the bios chip does more than just sit there and look pretty,it does have to be connected.

    Before you try glueing it with your conductive glue, test a little batch and see how fast the stuff sets; what kind of working time you have with it.

    I can't think of another way to connect it though, except to maybe try glueing some short, shielded wires to the chip and then to the socket points. The only other solution I see would be to set the chip in the board, then try to apply the glue to the back side of the board where the pins protrude the mobo, if they even do that.

    Solder it, conductive epoxy it, whatever. Still stupid. Epoxying the center of it to the board will hold it in place better anyhow.

    **Durr** I was going to suggest making it into a purty keychain... but now that I know it actually DOES something... :rolleyes:
