Pulled a chip of my 9700

#1
I just yanked a chip off my Radeon 9700 while trying to change to a new heatsink. It has eight tiny legs that attatch to the board. How can I reattach it? Does anyone know where to find soldering tips that small, or maybe something like a conductive superglue?

Yes, I know.:eek: I found out that manufacturers sometimes glue some chips to the board. I thought they were all just thermal-greased.

and ask a mod to delete this thread after said letter has been written... no need to give them any evidence ;)

I think "Handybuddy" hasn't replied yet because HE HAS NO GRAPHIC CARD!!! to log in to his computer..... lol :D :D

Q: Why "Handybuddy" disappeard from the forum
A: Because he yanked a chip off his Radeon 9700!!

Oh man it's bad! I'm still around. I went out the very next minute after it broke and bought a 7500 64MB (which WILL be returned for a full refund upon replacement ;) ). I think I may be stuck playing Icewind Dale for a couple weeks, though.

Rebuilding new legs with silver epoxy!

Another great idea. In case your card guarantee is overdue.

[edit] post edited... idea may be a little on the other side of the fence :)

keep posting though... - Sazar [/edit]

/me reinforces the idea that NTFS can not be taken responsible for any actions of our members... we do not support this kind of behaviour.

On a side note... thats always worked for me :p

Lol...I did that once with my Logitech MX500 just a few months ago...why didn't I think of that? And no, I will not implicate NTFS . org in any way whatsoever if I am caught in my unsavory acts.:cool:

Dear ATI,

I am so dissapointed with the video card i brought bearing your name. Recently I was dusting said card with my screwdriver, after i replaced the card in the PC and attempted to power up... I noticed this little 8 pinned chip embeded about 6mm into my wall.
I feel ATI should replace the card as the chip could have quite easily penetrated my left testical on it's wayward journey to the wall.

Also my dusting screwdriver is chipped after said accident, so another one of those wouldn't hurt either.

(you get the idea on the letter don't you):p :D

Call ATI tech support, confess what you did and see if they will attempt a repair for a flat fee, like $35-50. MSI has a deal like that on their stuff. I said attempt because if you ripped up any of the circuit traces or pads when you pulled off the part the board may not be repairable. If you do any additional damage trying conductive epoxy or soldering yourself they won't work on the board.

Now the technical stuff:
Don't even try to fix it yourself. Initial soldering on surface mount devices is done by screening a solder paste onto the board. Placing the parts on top of the paste and then running the board through an oven that flows the paste. Its a "low" temperature process that makes for weak mechanical connections (but you know that now).

Repair techniques for SMD involve heating the entire board to a high (but safe for the parts) temperature and then using a hot air jet to locally heat the solder past above it's melting point. The work is done under a microscopic viewer so you can actually see what you are doing with the tiny packages.

A conductive epoxy to reattach the part might work, BUT!
The epoxy will be a higher impedance and electrically noisy compared to the solder pastes so if the part is a high speed device it may not work or not work reliably.
The risk is also very high that you will slop some of the expoxy onto another conductor shorting something out. If it's a power lead thats shorted the card will be toast.

I used to do this kind of work years ago and wouldn't even think of trying it without the proper tools (that's about $10k worth).
We don't even have that kind of equipment at work (15,000 man aerospace plant) anymore. We farm the work out to specialty shops. Shame we don't have the equipment, could have used it to unlock my Athlon XP. ;)

What a long strange trip it's been. =)
