Help with identifing Caps from a 8800GTS Video card.

[KnownKiller]

Hello,

I just bought a damaged EVGA 8800GTS 320MB Super Clocked card from someone online. All the silver caps were broken off apon other things that were damaged in shipping in the past.

Anyways i need to know what these aluminum caps with a plastic base are called and were i could buy some replacements?

The guy told me the numbers off the top of the caps.

From top to bottom:

648
SVP
180
16

Ofcourse i have no idea what any of the numbers mean..

Please help me out.. i'm hoping i can repair the card and give it to my Godson for Christmas.

They are Sanyo OSCON SVP Series 180uF, 16V. They are classified as "Vertical Standard" sometimes mistakenly classified as SMD. The SVP series is 105C whereas the SVQP is rated at 125 C. I recently purchased 10,000 pieces on e-bay. Hope this helps..

648 - Package number
SVP - Series 105 C
180 - 180 uF
16 - 16V

This is so cool!

Please keep us posted with more pictures and results!

Good luck man, I hope the thing still works

[Goonda]

To answer your latter question, replacements can be purchased at Capacitors Plus or on e-bay. Sanyo OSCON caps are really really hard to find.

[aja]

That one chip (south-west of the white plug) seems really busted. Will this card really still work?

[Super Nade]

No it looks like somebody didn't de-solder the device properly and tried to yank it off. :)

[KnownKiller]

The original owner sold it to someone overseas and it was damaged in shipping.

Heres where the real trouble lies in the tear in the PCB where this chip was tore up. I hope to figure out how to fix this. i should check this area out first before i order the caps.

After looking at that ^ pic, I am starting to think your options are:
A - send the card for repair to the manufacturer (who knows, maybe it is not too expensive)
B - buy an identical card with a dead core or memory or whatever, and use the parts from that donor card. Seems a good choice especially since goonda said that those caps are scarce...
C - suck it up and call it a day

I would go with option C, considering that PCB tear. Those multilayer traces are impossible to fix.

[KnownKiller]

Bought the card mainly cause i love fixing stuff and it looked like a fun project.. I've never fixed something with a tear in the PCB and it looked like a nice challange. The harder it is to fix the bigger the reward when it fires up! :)

Plus if i get it fixed i'm thinking to give it to my Godson for Christmas.

I paid the guy $83.00 for the card and extra cooler.. Not gona give up till i figure it out.

[aja]

That is true about the reward factor:D

Are any other chips damaged?

[bing]

Wow, is that a wide open crack at the PCB under that cracked inductor (1R0) you circled ? :-/

[KnownKiller]

That is true about the reward factor:D

Are any other chips damaged?

No other report of any besides the tiny C33 resistor under that broken black inductor. The owner said he has it so that should be the easiest fix.

I'll know more when i get the card.. Said he shipping it out tomorrow via USPS Priority mail.

[KnownKiller]

Wow, is that a wide open crack at the PCB under that cracked inductor (1R0) you circled ? :-/

Look more like a top layer tear under the left pad.. hopefully its not too bad. I'll have to take that chip off to find out how many broken traces and if anything important under the top PCB layer. Woud be super sweet if i could just somehow glue the tear down and solder a new 1R0 chip and be done. But i'm thinkin its gona me a mess and i'll either have to buy some expesive tool or kit to get it done or send it out if its not too expensive to get that part fixed.

If i have it my way it will be new tools and do it myself as thats what i want. No money so it may have to be an early X-Mas present from the parents or something hehe.

I wouldn't worry, it looks like the silkscreen is damaged. Some nail-polish and you are good to go.

[KnownKiller]

Nail-polish as a sealent? Just cover it eh?

[Super Nade]

The picture does not tell a whole lot, but if the traces are o.k and inner layers are not damaged, I'd go with nail-polish presuming you are using this card in an extreme cooling setup. If not, be careful as nail polish is not the best thing to use on a PCB which is at say 60C.

[bing]

I guess nail polish as SN suggested is just good for sticking that peeled silk layer back in place if there is no crack at underneath layer.

But remember, that chipped inductor is swithing one and will be hot, worry the heat might affect that cured polish since they're basically low melting point plastic.

[KnownKiller]

Ok so say nail-polish isint the ticket.. What else? Epoxy?

[aja]

Ok so say nail-polish isint the ticket.. What else? Epoxy?

I have used epoxy to stick down integrated heat spreaders on naked CPU's and also some other non-PC circuits without any problems.

Spread a line of the stuff, let it dry, then measure with your multimeter to make sure that it is not conductive.

Hot glue from a glue gun works great, but the heat will probably burn it over time (those who have left a glue gun running overnight by mistake will know how bad the smell really is...)

[bing]

Although I'm not sure how bad that damage is, if I were you, I won't use any glue.

"If possible" without shorting or damaging any other trace, I will scrap clean that peeled silk screeen until the copper exposed, where the left inductor's pin is soldered to and just use a bloop of solder to stick it ! :D

Anyway that connection supposed to be thick trace since its switching power trace. Not pretty, but it works if done properly.

Also, as another insurance, I will trace that peeled copper's trace, and should be easy to add another parallel route from that inductor's left leg to that soic mosfet if I'm not mistaken (that Fairchild with F symbol), and that tantalum cap with extra wire to ensure low resistance path.

Again, just a suggestion. ;)

[KnownKiller]

Damn you guys sound like you know what your talking about.. hehe glad you found my thread.. Well i guess we'll have to wait and see how bad it is when it comes in the mail.

Thanks for all the advice so far.. Sounds like a have a few options anyhow.

[Super Nade]

I find it really hard to believe the seller's claims that it was damaged in the mail. Those vertical mount components don't come off that easy. You would have to twist and break. Can't yank it off without causing a huge tear in the silkscreen.

[KnownKiller]

I believe the guy said that the heatsink was not attached right or something to that effect.. He edited down the original sale post so i cant see it now.

I'm sure they were just damaged and he pulled them off..

Who knows.. It could all be just a cover for the real damage, that the card was fried. meaning the card was bad so do some physical damage to it thats fixable and see it for a decent price. Though he did have proof of the sale with the other patry and gave the heatwave names. I didnt check that but he did say that he issued a full refund to the past buyer.

Re-reading your post just now and it just dawned on me.. you said you just bought up 10,000 of these caps? Cant ya send 9 of them this way? lol

[Super Nade]

Watch the classifieds if you have access. I bought a few bags myself. These are very expensive and good luck if you can find anybody willing to sell double digit quantities. Apart from one or two vendors in the US I could not come-up with anybody who would sell a few at a reasonable price. I'm not gonna pay $5 for a single cap, :mad:

Sadly, there is such a massive industry wide demand for OS-CON caps, more so with big guys like the MB manufacturers jumping on them, that finding anything for prototype use is almost impossible. Note that the 16V high capacitance pieces are even harder to find.

[KnownKiller]

Holy cow batman, the card is coming in today as it hit my local post office early this morning! God i cant wait to see it.

Sucks that today the family is headin out to the Circus :( Damnit man..

What tools do i need to solder on a surface mount cap? A good heatgun? ALl the heatguns i see come with a 10x10mm 4 sided tip.. It would fit but theres only 2 solder spots on the cap.. Does that matter or do i need a tip that has 2 sides? I also have seen a pair of hot tweezers. Would that work ok as well?

So if i go with a heatgun i'll need solder paste as well right? Which kind? 200c Heatgun be fine?

Or do i just go with a regular cap and try to make it look as clean as possable using a regular soldering iron?

[KnownKiller]

Looks like i was sold a card that is not possable to fix.. i asked for pics of the memory chpis and that northbridge looking chip and if they had any damage cause they were all covered up with thermo paste and pads.

The seller (sabregen) uploaded 4 pics showing the chips.. ofcourse the pic with the northbridge looking chip was blurry and had some thermo residue on it so i really could'nt tell.. So since he didnt comment on the damage i figured he ment they were all good.

So i get the card today around 2PM.. All excited i open it up and pull the card out and look right at the chips and see some more chips that are nicked up that was'nt mentioned.. Ok so there may be a chance there still funtional.. Check the broken chip with the torn PCB under it and who knows if thats fixable.. I'll have to ask. Though once i look at that northbridge looking chip i see a chipped edge! Looks pretty major and toast to me! No chance for repair not reason to keep on debating about what caps to get and tools to buy to attempt a repair as that chipped chip kills the deal.

Check the pics.. Clear pics..

Let me know what you think.

[Super Nade]

I'm not sure. I have never torn an inductor clean off of the PCB. In theory, it looks like the silkscreen has come off and it is fixable, but the big question is, without the silkscreen to indicate placement, where will you put the replacement part? Also, if you see a trace on the under-side of the peeled layer, your card cannot be fixed.

[aja]

Sorry knownkiller :(

I was looking forward to a successful revival...

[bing]

Forget bout fixing, even the nicked chip is still alive and you have the replacement for the inductor and the caps, there are alot of other missing components like smd resistors and capacitors. Wonder what happened to it, they smacked it on concrete or what ?

Bummer ! :(

[largon]

That one chip (south-west of the white plug) seems really busted. Will this card really still work?The part's perfectly intact, the white part is just a fragment of HSF TIM stuck on top of the chip.

The guy sold me a damaged in shipping graphics card.. I knew about most of the damage but not about that chipped nvidia SB looking chip.. which i asked about before i bought it.. he showed pictures of it that were dark and you could'nt tell. No mention of damage on it so i took that reply as its good.

Now because of that i bought a non-repairable card and i'm fighting the guy right now on [H] forums. He feels he's not in the wrong and i knew what i was getting into. No refund offered.

Just filed the transaction on paypal and i'm prob going to escalate the claim ASAP once he makes it known that he's not gona refund me to paypal. hopefully paypal will look at this fully and not just see a damaged card and say too bad.

No return policy stated, sold it as a repairable card to those with the know how. Priced it expensive originally at $150 also stating it was an easy fix. And not informing me of the damaged chip that i asked about before buying is where i'm ****ed and on a rampage about getting a full refund.

[JamesXP]

[H] = :mad:

[KnownKiller]

Welp paypal dont care.. Infact they didnt even spend a min deciding in his favior as they dont care about the condition of a received item. Only that you got it.

Left him a Negitive feedback in his heatware (sabregen). Gona call the bank and see what i can do there on Monday.

Would'nt care if i didnt ask about specific damage to the chips i asked and was lied to.

I'll also add that the Sellers and Mods over at Hard really backed sabregen! I guess they dont care about the way sellers sell there stuff there even though there is an outbreak of scamming going on according to what sabregen told me eariler. No respect for there mods as they spoke negitive opinions about me. Just about everyone there said they would not deal with me and IF i should win the paypal case i will be banned! lol.. Nice set of people there i tell ya! Some buyers would chim in every now and then and defend me but most of the time they didnt want to speak in public and only PM me support in fear of making anyone mad at them.

Not going back there again! i'll stay here at ocforums were theres nice sellers and i've never had any probs. :)

[Super Nade]

Send me all the info about your case, including PM's and links to the original thread/posts. I'll take a look .

I sent you all the other stuff you requested though i forgot the original sale thread. Not sure what use it may be as the seller edited the original sale post. Which i might add to me isint a very smart thing to do when something happends like this.

Got soldering skills? 8800GTS 320MB SC damaged w/all parts and TMG ND5 Cheap (http://www.hardforum.com/showthread.php?p=1031648686&posted=1#post1031648686)

Clearly the guy did whatever he could to sugar coat the card to sell it and make back whatever he could cause he claims that the card was damaged in shipping on its way to the original buyer in India. The said that he made a mistake by not tighting down the screws on the stock heatsink when he packed it up lol.

The original pics had thermo pads and goop under the pads covering up the real damage to that nvidia NB like core. Said his soldering skills are limited and all he can do is tin some wire ends.. lol. Just funny now i know the whole story.

Showed me the pics of the areas i marked that i wanted to know if there was any damage. The pics were all dark and you really could'nt tell. THough i figured it was thermo compound residue on the chip as most chips had the same crap on them. That and since he didnt say there was and his price was the same at $150 it was good to go.

Luls.

[KnownKiller]

I just shot off an email to evga support to see if they can fix it or suggest what to do other then mailing it off to the seller with a nice surpise in the box!

Its a long shot but i aint got nothing left to loose.

[magick_man]

Just wondering if anything ever happened with this?
Sucks that you got screwed.

~Magick_Man~

[KnownKiller]

Evga said they would'nt fix it.. Figured that but it took them over a week or so to get back to me.

Paypal screwed me as they didnt bother even looking at the claim at all and claimed it was'nt covered.. They dont care about the quality of the item recieved, only that you recieved the item.

I ended up using a tiny resistor off the card to fix my 8800GTX that i messed up durring a volt mod. Thats all good now. Also someone wanted the card for parts to fix his up so he could RMA it. SOld it to him for $40 shipped. So i guess in the end the bad card went to fix 2 other cards hehe. All good!

Oh and i almost forgot.. The seller just gave me a negitive feedback on my heatware account! Sneeky guy i tell ya.. Waits like a month and then bam! Theres a retalitory negitive feedback since i gave him one.

Oh well. Looks worse for him as i was only a buyer and not the seller.
