Fuck, so much bad advice.

Reflow by unplugging the fans is not a reflow at all. You may damage the procs on the board.

1000f heat gun is going to warp your board or do a shit job reflowing. The time is about right though, some times it took 15. Correct temp was 350-380C. Chip itself gets up to 200 or so... i checked with a IR temp probe.

Reinstalling the clamps leads to repeat failure as the clamps move the board while screwed to the casing when everything heats up. I read this was a contributing factor in the failures based on varying rates of expansion/contraction in the metal.

My Nvidia reflows tend to last over 6 months. Xboxes were hit or miss, some kept going forever some lasted a month. The older ones tended to stay fixed while the newer ones were more flaky. Also there is more than one RROD code, some fixed very well some were a matter of luck.

See how hot the chips get. Maybe its perfect b/c of overrating.

That's what I'm thinking.
Next time I reflow, I'll use a IR probe.

Thanks for the correction.

My assumption might be correct though that the clamp fix might encourage tin whisker growth:

Externally Applied Compressive Stresses such as those introduced by torquing of a nut or a screw or clamping against a tin-coated surface can sometimes produce regions of whisker growth.

Another benefit of the EuroSoc ROhS. I think they mention that adding even a teeny bit of lead alleviates this problem. But thanks to RoHS, even that's not allowed. I'm aware that sometimes you need a non-eutectic solder because of alloy migration during reflow, but adding even minute amounts of lead is prohibited. Another completely retarded law that has no valid reasoning behind it.

Why don't you just reball it? You can get leaded solder balls from China off eBay.

Problem solved.

I wouldn't buy solder balls from china unless some Chinese bitch sucks my dick and gives me money.

Sorry I'm on a anti-china tirade. I went to buy work boots the other day. I was looking for boots made in the USA, turned out they were all made in china. I went to a army/navy surplus store same thing. Even the basic issues were made in china. Then they wonder why America's gone to shit.

Anyways
I don't have the tools to remove the chip or the skill to perfectly lay the balls back on the grid.

The only thing we manufacture now is financial products. If you think China's physical products are junk....

Re-balling is too much work.

Should be high quality. China has a lot of experience selling us stuff with lead in it (mostly paint on children's toys).

Time to crack it open and hack the drive. I wonder which drive your unit has.

Definitely bad ideas.


If you want to fix the issue properly you need to do it properly. That means bottom side preheating the board to avoid warping, but not overheating and cooking anything. You can do a perfect reball on the IC but if you warped the board then it was a waste of time.

You might even need to bake the board first at low heat to remove moisture and help prevent popcorning.

Then heating the IC from the top itself with a proper heater, not some cheap heatgun on full power. If you go too high you cook the IC.

(Note: this previous is stuff I have gathered from research not practical experience)

I tried to reflow mine by overheating. It worked, for two days, then a week, then one day...Finally I resorted to the oven trick. I didn't have a hot air rework station at the time and I was desperate. hehe

I also took the dvd drive out and have it mounted outside the xbox sitting on top. Right below it I cut holes in the case and mounted two fans blowing straight down on the vid chip and HANA chip. It's been working great ever since.

The oven trick, btw... I double wrapped the board in foil leaving the top and bottom side of the two chips exposed. Preheated oven to 500 and threw it in for about 2-5 min. I do not recommend this method to anyone. But it did work for me.
