Been scrambling all over the net looking for a good conductive silver paint deal, but found no info on what temperatures this stuff can withstand, and if its really safe to use under gpu chips. Found 1 product that copes with 150c but how hot does a 360 gpu get..???? I've never tested one for max running temps.

I'm thinking It's more about the re-seat process where we have to take the temps over 190c or 230c if unleaded. How will this stuff cope with 230c ? For a safe no-come-backs repair, perhaps were looking at a specialist silver paint at £35+

I'm going to hunt out mid range product of this stuff, and as soon as i get a board that's ideal for testing i will pull two pads on a gpu and redo them, and if xbox boots up... hard core gaming for 8 hours, that's the boys job i think.. ... sorry neighbors.. lol

This stuff is great, its a dam good idea, but it looks like it's meant for tracers and not for grumpy old gpu's that like to cook their own balls and eat them.. :lol: :lol:

Good idea. However, I only use lead with my reballs so I can't comment on an unleaded profile. If you find the product, please share. Thanks.

i dont think an xbox gpu under standard running temps wud go much above 100c, maybe some one can confirm with a special, also i cant see why anyone would reball a gpu with lead free solder balls, can u even get them? id be suprised lmao, in theory anything thats condustive wud work so test things out lmao

I agree. Who reballs with lead free? Defeats the purpose. The only things I need lead-free is gas, water and household paint.

True true, I agree on the unleaded being a rare requirement. So It's temps of 190-200c and a silver paint that wont break down at those temps and just blend with the solder its up against. I believe orange insat flux allows the leaded solder to react at lower temps which will help :? can anyone confirm that?

Here's a data sheet from one product .... http://www.hkwdirect.net/acatalog/techpdf/044SCP.pdf from CMR-Direct Which copes with 150c ... which isn't enough for re-attaching.. Can't find any real data on the cheaper stuff.. The only way is to do some test's with silver repaired consoles..

Perhaps its just a case of using the silver to get the ball/s attached to chips wire in pad whole, as once on the board it holds position around the wire.. guess-work..!!

Anyone got a console running with silver repaired bga yet? I'm going to try it with a box I've got on ebay, should be with my by Fri.. Fingers crossed


It will be this one first... http://uk.rs-online.com/web/p/conductiv ... 435892|cav

Against this one after... From Ebay item no. 300882001285

Out of the two silver paint brands i tested there isn't much difference. On both accounts after pulling the gpu and cleaning, the pad whole was still visible under a scope. This does work after attachment , and I've had a box running for three weeks on a repaired pad on a 360 hdmi.

It's a great idea and worth doing. I'm just prodding along with the 360 to see how long it last's. If i get 3+ months out of it, then that's good enough to start using on customer consoles... Nice work tahitian954 looks like a good repair procedure
