Unfortunately I'm back with more questions, this time a different board.
This is from a Dell Precision 380 mobo, where the one capacitor seems to be bulging near the memory slot. I've been having BSODs and memory issues with this computer lately, and I suspect this is causing the problem.
The capacitor is a KZG 820 uF 6.3V (I think 8x11.5 mm), know a good alternative I can go for to match the ripple current/ESR of this cap? I hear KZG caps isn't great...

Re: Intel D865PERL caps
I actually couldn't find the specs for the soldering iron, and it's fixed temperature so not sure what temperature the tip is.
I did have trouble at first though, mixing in a bit of new solder helped melt the old solder and the caps came out no problem.... -
Re: Intel D865PERL caps
A 30W soldering iron, although I was limited in this case, typically I'd try and get a 40W... and my precious fingers to pull the caps off once I've heated the joints. Crude but effective.
I use a manual pump to clean the holes and a desoldering wick for anything left over....Leave a comment:

Re: Intel D865PERL caps
Thanks all for the help, youre suggestions worked out well momaka. I was scared at first about going from 10V to 6.3V, first time I went with capacitors of slightly different specs.
Anyways, ended up going with Panasonic 2SEPC820MY and Nichicon UHN0J222MPD. Had more troubles figuring out the software issues that came from me resetting the CMOS than the actual desoldering and soldering the new capacitors in.Leave a comment:

Re: Intel D865PERL caps
Thanks a lot for the reply and information, I was totally lost about these older boards. Preferably I would go Digikey, ideas on equivalents? I've looked and it seems they've discontinued exact models. If it is a total mess finding equivalents for those two capacitors then I have no issues going through badcaps.
Phew, it's good to know that not all the capacitors on this board (actually there's 4 boards) aren't completely shot. May order extras in case of future issues....Leave a comment:

Intel D865PERL caps
So I have a bunch of computers with D865PERL mobos which all have similar caps that have either buldged or burst. Their ages match perfectly with the bad batch of Nichicon caps that were supposedly overfilled and burst prematurely. Unfortunately, given the age of these boards, it's not obvious what the replacement would be for these caps. Suggestions on good equivalent replacements?
The caps (had to tape measure the dimensions so they may be rough):
Nichicon HM(M) 2200uf 10V ~10mm(d) x 22mm(h)
Nichicon HN(M) 820uf 6.3V ~8mm(d) x 20mm(h)

4W laser?! What in the world, who throws that out into a dumpster!...Leave a comment:

Re: Your Best Dumpster Finds
I looked into this more without directly asking, and that's totally the case for my university too. I think you're allowed taking, but there's a metal scrapper who comes in to take stuff that's basically given to him on a silver platter. Unfortunately, they throw out perfectly working equipment and components that we typically and otherwise buy new. Not super efficient system....Last edited by splur; 05-31-2014, 11:05 AM.Leave a comment:

Re: Your Best Dumpster Finds
Not sure if this has been mentioned, but if you find the "recycling" area in any university building aka basically where the department pile their old "crappy" electronics (preferably if you're a student or friend of a student in that specific department, otherwise it'd be considering trespassing), you tend to find some really interesting things.
I happened across plenty of Pentium 4s, computer components and PSUs, old DAQ chips and boards, if you're lucky junk instrumentation with interesting components, monitors;...Leave a comment:
