Missing Ceramic Capacitor

[JarJarBanksy]

So I screwed up. I managed to knock a capacitor off of an EVGA GTX 460 2WIN graphics card. This capacitor is labelled C1550 and is likely used in the process of supplying power to a RAM chip. What I am looking for are the specifications of that capacitor. I am looking to replace it under the likely circumstances that I can't find the darn thing. It is between 1/16" and 1/8" long.

 

Here are some pictures.

lol you seriously think you can solder that tiny component using a normal sized soldering pen?

It will probably ruin everything around it in the process.

 

Can you RMA it?

[TheKDub]

 I'd suggest RMAing it if possible, its not likely that you will be able to solder a new one on.

[Syntaxvgm]

You sure can solder those, but you'd better be good at it, and practice a few times on old boards first. 

If you are clumsy enough to knock one of those off, I doubt you have steady enough hands for it. 

How do you find one? From another dead or dated card, that's where.

Just get it RMA'd. EVGA won't be mad at you for it, and they'll most likely replace the card under warranty.

Yah try that first

I'm pretty good at soldering and I find those to be a bitch. If you can, RMA the card. If not...practice makes perfect I supposed. Might be able to find an electrical diagram for the card somewhere on the internet, maybe.

I solder guitar parts all the time. Won't go near with a 50 foot poll.

yah it's really hard to track down the correct documentation for it. I just make educated guesses and use broken donor cards. They generally have, in the least, the same ones in the direct vicinity.

"Close enough" works with electronics...right??

Worked just fine for me so  far. For last ditch effort , I'm ok with close enough. I mean I reflow shit all of the time too.

I see that as a "well it's already dead to me as far as I'm concerned..."

I do try to use cards of the same series as donors though. But I did fix a 5770 with a smt cap from a really old gpu, like a AGP one I think once. 

 

And 90% of the time I reflow something, it's fixed. I'm pretty good at knowing if it's that type of issue before I try it. And do deep even bakes to make sure I doesn't break again in a couple of months, non of that heat gun shit.

Oh god that reminds me my friend tried to heat gun a laptop gpu to reflow it after the thing stopped working... All he did was melt the thing.

I think the world is trying to tell you to upgrade. Good luck on soldering if you go that route.

Yah if you are melting something, you don't know what you are doing =)

Best left to experienced laptop repairmen.

I did leave a CMOS batter in a PS3 once. 

POW! 

Oops. Luckily it didn't damage it.

smd components can be tricky if you dont know the correct technique to hand solder them. I dont know about the specs on the cap, but it is definitely one of the easier smd parts to replace. What i do when dealing with parts like that is i put some small dabs of solder on the solder pads and lay the component on top of the solder pads and lay the iron across each end of the part until the solder melts and wets the ends of the part. Thats what i have always done.

Your friend might not have had a clear idea of what he was doing. Heat guns can get seriously hot.

This is some very helpful and useful advice. Thanks for the tip. I'm certain that I would not have thought about this myself.

You sound like you have experience in tracking stuff like this down. Would you have any recommendations on where I can begin my search? Any repositories of such schematics?
