Re: Need to find caps

talk to topcat you need 6.3v (or higher) 560uf caps. must be 560uf since thats the marked value. samxon will work fine or go rubycon if you want the absolute best. since you are in between memory chips, id pay more and get rubycon since it can get hot there

ps, try to get the physical size right as well. get out a ruler/tape measure and measure in mm of both diameter and height.

pps. any other nichicon hm/hn on there/ replace any of those as well since those were a bad model. brand on yellow caps?

Re: Need to find caps

talk to topcat if you are in the usa/canada. you need 6.3v (or higher) 560uf caps. must be 560uf since thats the marked value.

if not, get samxons from big pope or go to digikey for panasonics (pannys). the board will love you for it

ps, try to get the physical size right as well. get out a ruler/tape measure and measure in mm of both diameter and height.

pps. make sure the the caps are low esr or ultra low esr

ppps. any other nichicon hm/hn on there/ replace any of those as well since those were a bad model. brand on yellow caps?

Uhg if i have to replace all the caps its going to turn into an expensive repair job.

Re: Need to find caps

question- do you want the board to work for sure or not. caps often fail without visual signs. since you have no esr meter, you will have to replace all the bad model/brand ones. remember you get half off caps since you are an active forum member.

Re: Need to find caps

Half off? whare do i have order them from Topcap?

yeah want the board to work but ive never replaced caps before and the computer place charges by the hour and the other one is 10$ a cap if i am not in a hurry.

make sure to measure the lead spacing on the bottom, too

Re: Need to find caps

yeah, order them from topcat. he gets them in bulk and even samxons would do fine if money is a concern.

Re: Need to find caps

do you know how to solder?

to recap, you need:

a GOOD soldering iron/station, 30 watt, ones with a tip holder like this:



that is the international vs of mine, xytronic 258 adjustable temp grounded professional iron.

it disassembles by a sleeve being threaded over the shaft with a flanged tip in between.

dont buy one like this:



the tip is a shaft with a tip held in by a screw. poor heat transfer, bad quality, not grounded, and unlike the one above, no replacement/different tips are available.

for solder some recommend 40/60- i use silver-bearing. make sure it is thin spooled kind

for solder suckers, do not use this kind:


or


those are pogo stick plastic or plastic-aluminum hybrid suckers. the threads holding it together will strip and fail, often shooting a tip across the room and possibly breaking a window/hurting your self

admittedly, i use pogo stick myself. mine:



it is of all aluminum construction

some, particularly kerijane, like this kind:



it has a softer touch and if you are not keen with you thumb, you dont have to re-cock it. they spill old solder when turned tip-down and are hard to clean

some will swear by desoldering irons and guns, but good ones cost a real boatload

if you have a stubborn joint, mix in a small amount silver-bearing solder, make it melt better

get a good stand:



if you are using an iron

buy your tools online or at a local electronics shop. don't go to radio shack, their tools are flash overpriced crap. i had to replace almost every tool i bought there... the local shop had same prices but better equipment . pay for quality, not flashy-ness and and extra middlemen.

Re: Need to find caps

uh yeah ill look into that for when i do try to do a recaping but i am just going to send it to Topcat for now
plus i tend to get a little shaky with my right hand at times.

[ratdude747]

Re: Need to find caps

good idea. my hand was shaky resulting in many botched jobs. but a good iron and practice made it work.

btw, you seem to reply fast. im 17 and i thought i was fast but ive seen nothing i see

[Phaihn]

Re: Need to find caps

lol i wait for a reply plus i usly get lucky and i am 26.

[Phaihn]

Re: Need to find caps

Yeah ill have to practice on a dead board or the one the computer place guy gave me.

Re: Need to find caps

Sex is the only thing a man does faster without practice.

OP, learn to go slow and careful on your recap jobs.
Speed comes with repetition.
A fast, sloppy job winds up as a DOA board, and a re-do.
Pull the new caps you just bought, throw 'em out, go again.
Dumb.

Like painting, the quality is in the prep work.
Use a 450C tip to de-solder and remove your caps.
I have good luck with both the sucker bulb and stainless needle for cleaning holes.

Re: Need to find caps

fyi, my iron shown above is a 430C at max temp, it does fine.

i thought that was a bad thing, right.

You can buy compatible replacements from here, ebay, or at Mouser.com

The caps with the "X" vent and black sleeves/gold stripes are probably Nichicon HN. If you buy caps from here, make sure to mention that to Topcat so he can give you compatible low-esr caps. Or if you buy from ebay, look for Rubycon MCZ or Nichicon HZ as those should be compatible as well. Otherwise you can buy the same Nichicon HN caps from Mouser - and don't worry, it's unlikely that they will fail. Reason why is because Nichicon HN and HM had problems with caps made before 2005, but are okay since then. I doubt Mouser will sell you old caps.

Also, check the brand/model of other caps with "X" vents and black sleeves/gray stripes near the PCI slots. If they are Nichicon HM, they might need replacing too (just look for a 4 digit date code on them where the first 2 numbers represent the year - if it's 04 or less, they can be bad). Anything under 470uF, however, doesn't need to be replaced unless the motherboard's problems still persist.

I am just sending the board to Topcat any-caps that need to be replaced will be replaced.

Re: Need to find caps

brand on yellow caps?

Fujitsu polymers

Good brand

to the left of them is another nichicon, as well as those UCC's look like KZE's from what I could see, those may be from the defective series, maybe not.

[momaka]

Re: Need to find caps

I think only KZG (and possibly KZJ) had heat-related problems. KZE uses different electrolyte and their ESR isn't as low as KZG and KZJ.
----
On Phaihn's board, the KZG caps seem to be on the high-side of VRM so they probably aren't as stressed as the Fujitsu caps on the low-side of VRM.
