Physically replacing a chipset on a Tyan MB

Recently one of my computers failed.
It wouldn't even post.

After checking everything I sent the MB to Tyan to see if they could fix it.
They tell me that the chipset has gone bad.
And that it can't be fixed.

I have an old piece of software tied to this board. The vendor has gone
out of business, so moving the software to another computer can't be
done.
Tyan is shipping the old board, and a replacement board to me.
(The replacement is supposed to be the exact same model.)

They say that they can't replace that no one can physically replace
a chipset. It messes up ... something.
Is that true?
Shouldn't a talented person be able to take the chipset from
the replacement board, and put install it into my old board?

Thanks for your thoughts

  1. No. Only a bios chip on some older boards can be replaced. The chipset is soldered on through severals layers. I used to work at an IBM plant in austin that processed printed wire boards. You can't repair them. Pulling out the old chipset would cause too much internal damage.

    Chipsets are ball grid array parts, which means they are electrically and physically attached to the motherboard by a series of small solder balls. It looks a lot like what the bottom of a pinned CPU like a Phenom II looks like, except the pins would look much shorter. The chipset is then set on the board and heated to melt the solder (reflowed.) You would need to heat the little solder balls and then remove the solder with a vacuum desoldering tool. That would literally be an impossible job to do- basically think of aiming a tiny desoldering tool at each and every pin on a CPU and removing all 1000+ pins. Secondly, even if you did manage to get the chipset loose without destroying the motherboard, you need to get a new chipset IC (good luck!) and heat it just enough to get the solder balls to melt without overheating any of the surrounding components. Basically the only way you would be able to replace the chipset is if you had access to Tyan's reflow station equipped with the correct reflow jig for that chipset IC and their stack of chipsets. Since the board is out of production, the chance of that happening is about nil.

    The bottom line is that you would be much better off just looking on eBay or a used computer reseller's site for a board that's identical to your first one.
