Some of you know the whole story. I used liquid flux on this box did the heat gun I just now decided to look at the board to see what I may have overheated and to my surprise this it what I saw. What the hell did I do?
Yeah, sorry to say but this looks bad. Looks like a few things kept feeding the chips juice and the system was prevented from shutting itself down. Bridged points, blown caps...improperly grounded board...all things that could have caused this. This one is gone...pretty sure.
I was thinking the same, did you follow w00ly guide? It does say in there to remove your heatsinks. Also, how did you get your liquid flux under the GPU & CPU without removing these?
Now I know I'm a noob but I'm not that much of a noob that I would forget to remove the heat syncs as well as the thermal paste. I put the liquid flux directly underneath the GPU top side of the MOBO. I didn't put anything under the CPU as I figured the problem was with the GPU. I looked at this youtube tutorial which was the only one I could find http://www.youtube.com/watch?v=h2R_NqF5wAc. Now the flux did end up running throughout the board and a little ended up getting directly on the chip I did try and take a tissue to pick up the excess liquid. I did the normally heat gun routine which I've done a good four or so times used the purifier and put the thermal paste and the heat syncs back on. The only thing different about this go round was the liquid flux.
My bad if I answered back late and everyone lost interest in the post but it would be nice to get any final verdicts cause there were some assumptions made that were not the case.
Heh i think the final verdict is that it's dead...whether you did the reflow with the heatsinks on or not is irrelevant really--if you have the kinds of heat that create those kinds of scorches then something has gone wrong that cannot be repaired at home (and likely wouldn't be worth fixing professionally). In the other thread you made for the same issue, you said the fans didnt turn on and the power brick went red. This (coupled with the scorching) is a sure sign that there has been a short circuit for whatever reason. Maybe you heat gunned for too long or stayed in one spot too long. Maybe you used the wrong flux. I've seen people put pressure on the chips after heat gunning, that could certainly bridge some connections if the chip is crushed down. It's hard to say what's happened really...something tells me you did something besides using a lead free solder flux and my heatgun method because I've certainly never had 360s go all thermonuclear like that (though I dont use flux, miketrev does and he's never had this issue).
Once again guys are making assumptions. I know that its..dead I've accepted that already. All I wanted to know is what I did thats all I asked. The reason I ask is because I don't EVER want to do that again so it makes sense to get evaluations to the mistakes made. Thanks for all advice. Also miketrev what type of flux do you use exactly?
of course we make assumptions. You give us a picture with burnt heatsinks and ask "what's the final verdict"? What do you expect? As far as what you did, it'd help to know what you did. What kind of flux did you use?
this is what I used http://www.hardwareandtools.com/No-11-4-Ounces-Liquid-Soldering-Flux-30106-by-Oatey-6713317.html
That flux is for plumbers welding copper pipes together. The type of flux you wanted is a no-clean one designed for use with BGA reflows on lead-free solder like this: http://cgi.ebay.com/Xbox-360-PS3-BG...ZViewItemQQptZVideo_Games?hash=item414defe3d3
Go figure >< its what I get for being impatient I should have confirmed it with you guys first. I assumed as long as it was a no clean then it would be the same. Oh well I just hope my drive is ok.
