lysaer Posted March 21, 2013 Share Posted March 21, 2013 Used some thermal epoxy to hold some heatsinks onto the card, as I was removing one it pulled the IC off, the legs are still on the board, but it doesn't look like i can solder it back onto the IC. does anyone know what these IC's are and where to get them, I tried googling the code but nothing came up http://postimg.org/image/6xsb4youb/ Thanks in advance Quote Link to comment Share on other sites More sharing options...
riska Posted March 21, 2013 Share Posted March 21, 2013 Thats not a ic it is an tantalum capasitor at 330 microfarad and 2.5v Quote Link to comment Share on other sites More sharing options...
xxbassplayerxx Posted March 21, 2013 Share Posted March 21, 2013 Those are just tantalum capacitors. 330 is the uF rating. They're not hard to find and they're not expensive! EDIT: Ninja'd. For the record, they don't need any sort of heatsink, either. Quote Link to comment Share on other sites More sharing options...
lysaer Posted March 21, 2013 Author Share Posted March 21, 2013 I'll have a look on the rs electronics site now Thanks a lot guys Quote Link to comment Share on other sites More sharing options...
lysaer Posted March 21, 2013 Author Share Posted March 21, 2013 either of these ok then ? http://uk.rs-online.com/web/p/tantalum-capacitors/7372838/ http://uk.rs-online.com/web/p/tantalum-capacitors/0147639/ Quote Link to comment Share on other sites More sharing options...
Eeky NoX Posted March 21, 2013 Share Posted March 21, 2013 Best place to get a quick answer, great reflex ...but go for zombie ^^ Quote Link to comment Share on other sites More sharing options...
lysaer Posted March 21, 2013 Author Share Posted March 21, 2013 Best place to get a quick answer, great reflex ...but go for zombie ^^ go for zombie ? I'm confuzzled Also I can't seem to desolder the copper legs from the PCB, would it be ok to solder a couple of pieces of wire on the original copper legs then solder the new capacitor to the wire ? Do I need to use a specific wire or does it just need to make sure it can handle 2.5v ? Thanks again all Quote Link to comment Share on other sites More sharing options...
xxbassplayerxx Posted March 21, 2013 Share Posted March 21, 2013 You can probably just stick this one right where the old one was and solder to the old legs. The solder used in the production of computer components has much higher melting temperatures than standard solder. If you want to work with it well, a hot air station is the best.

xxbassplayerxx Posted March 21, 2013 Share Posted March 21, 2013 (edited) That's a choke! That, the mosfets (the small, square black chips to the right of the chokes), and a few other components make up the VRM.

Bobnova Posted March 22, 2013 Share Posted March 22, 2013 You can almost certainly run without that one capacitor. You'll have a tiny bit more ripple, but odds are it won't make a noticeable difference. Quote Link to comment Share on other sites More sharing options...
zzolio Posted March 22, 2013 Share Posted March 22, 2013 just run without it, no problem if you want to run with ln2 then solder a new capacitor on Quote Link to comment Share on other sites More sharing options...

lysaer Posted March 22, 2013 Author Share Posted March 22, 2013 Before I go soldering this on the wrong way, which way onto the PCB should this cap go? Thanks in advance Quote Link to comment Share on other sites More sharing options...
xxbassplayerxx Posted March 22, 2013 Share Posted March 22, 2013 The side with the darker bar is the positive leg. That should go to the side closest to the chokes like the grey bar on the other caps. Quote Link to comment Share on other sites More sharing options...
Bobnova Posted March 22, 2013 Share Posted March 22, 2013 The side with the darker bar is the positive leg. That should go to the side closest to the chokes like the grey bar on the other caps. This. Unlike electrolytic and polymer caps where the - pin is marked, tantalums mark the + pin. Quote Link to comment Share on other sites More sharing options...
lysaer Posted March 22, 2013 Author Share Posted March 22, 2013 It's all soldered back together, I haven't had a chance to test it yet but I'm confident it's all fine. I opted to solder 2 wires parallel to the board pointing upwards so they ended in between where the gap is between the capacitors, then I mounted the capacitor there. It was easier than trying to fiddle with the leg next to the choke. It came out pretty neat, I <3 my flux pen. EK block is on and I will give it a test Sunday as I am off to the gf's tonight. Thanks a lot for all the help everyone I'll let you know if it's all good Monday most likely. Quote Link to comment Share on other sites More sharing options...

lysaer Posted March 26, 2013 Author Share Posted March 26, 2013 Photos! It's all already taped up safely and blocks are on :-( And I'm never ever ever taking the ek bridge off again, getting those o-ring gaskets on was worse than soldering on the cap, it took me like 2 hours to get all 6 in place lol. Haven't had time to test it still though was at the theatre last night seeing Wicked, but I'm confident in my soldering skills so all should be good Quote Link to comment Share on other sites More sharing options...
