Maybe you need to move gun around more?

Clearly heat is the issue to make it bubble, so you need to adjust something to make it heat up to less temperature or more evenly.

I'm moving it in fast circles, never stopping in one place. I will try to do it on lower speed only and see what happens. And aside of bubbles, after the heatgunning, that part of the board is slightly darker, like burned, is it normal ?

No, re-read the tutorial on page 1 and its all there. It should look the same after as before. Maybe you should go and buy a new one??

I just bought this one, it is new

I red a bunch of threads about heatgunning and people are saying that most heatguns hardly make over 220 degrees needed for reflowing, and all of a sudden I have one that burns everything in 3 minutes

What make and model of heatgun do you have?

I just tried heat gunning a 360 board that couldnt be fixed by x-clamping it however I had a quick question before continuing. I just isolated the caps etc. with some plastic foil and metal foil but when I turned on the heat gun all the tape holding down the foil shriveled and the foil started flapping up. From reading other bits of this thread I decided to stop and find out what tape everyone else uses?

It's Einhell bhp 2000.

I will try on lower speed for 4 minutes on some broken board, and see if it will melt the solder..

Try the modified "sticky blue" method. It uses putty like "sticky tacks" to cover the caps and also oven bags and aluminum foil to isolate. I've never had a cap blow, the putty stays perfectly intact and the plastic oven bags barely melt.

edit: the tutorial doesn't mention to use oven bags, but use them. You should be able to find them at a grocery store. Also, fold them in half for extra protection.

:evil: Killed my first motherboard today!!!

Thought i would be clever and use a modified fire sheet to isolate everything, however what I did not realise is that the tape does not stick the sheet properly due to the chemical!!!

Need to think of something else!

I have a question.
How did everyone form the aluminum foil around the plastic isolation. This is tougher than it sounds for me.
Do you tape the aluminum down?

Just wanted to tell you I found a great material to use, found it at home depot. It is called a heat cloth by Benzomatic it shielded heat up to nearly 3000 degrees. Use the putty, oven bags, the heat cloth and two layers of foil and I don't see how you could heat this up wrong.

I didn't buy it though it was like 15 bucks instead I am using multiple methods, blue putty, then 2 milimeter drop sheets doubled, wielding apron cut to fit, 2 layers of foil and then finally a disposable cookie sheet cut to fit around it.

Oh I am using oven bags as well forgot to mention that.

I'm gonna try this method, but I have a few questions.

1. Temperatures of my heatgun are 375°C and 500°C for the second step. Is that okay? I assume that 500°C is enough, but is 375 too high for warming up?

2. Should I heatgun both sides? If yes, do I heatgun one side completely, wait till it cools down and then heat the other side or what?

3. Do I wait the mb to completely cool down before I attach the coolers and X Clamp fix again?

4. Do I tape the aluminium foil or just the plastic one?

I tried to fix E74 with clamp fix and with heatgun. After heatgun my box get 3 red lights (no video and no audio). If i keep my box on and wait about 5 minutes and restart its working at least half hour (not tested more). But does anyone knows where problem might be? Is it related to ANA/HANA or southbridge? My box is falcon bought (11/2007).

I used heat gun with 1 minute warming (about 300 C) + 3 minute. Should I use 4 minutes with full heat (about 500 C).

cant get hold of a heat gun but will a good hair dryer do the trick ? it a powerful one !
as if the xclamp dont fix my 0020 error ill give this a bash, failing that a new 360 !!!

I've got infamous E74 (1022) on mine Elite (Falcon)

Because I don't have a heatgun and didn't wanted to buy one I've decided to look for alternatives.
And yesterday I borrowed AYOUE 710 IR welding station. I did reflow top side of GPU and HANA. 1 min 300C, 2-3 min 480C, then again ~1 min 300C after cool down (~5-7 min) and it worked !!! This morning ~7 hours after reflowing it worked also. Almost forgot to mention that x-clamp fix was applied after reflowing.

I thought about wilhelm's words on cool down time about 40 min, but maybe because using heatgun you heating not exact chip but also surrounding elements and the board itself, so maybe that's why using heatgun system must cool down (much) longer than using IR soldering station.

Any thoughts ?
Because this is first time I even see this equipment (IR welding station) and mine knowledge about electronics is basically only in theory so if anyone think that I did something wrong please don't hesitate and let me know.

hi guys, i've just tried heatgunning my xbox xenon motherboard, was getting the e74 at first then red ring with the error code 0101.

so i heatgunned my xbox and left it for half a hour as stated, now im gettin a 3rr and error code 0022..

this is sayin gpu error or gpu overheating.. i've applied plenty of thermal paste and that so it shouldnt be a problem.. any ideas?

nagamin · « **Reply #374 on:** June 10, 2009, 02:17:00 PM »

That is what I'm looking for. It is expensive equipment. It coast about 1200$.
MS repaire facility might using it. It is especially good for Hand Phone.
