T40 BGA problem solving without specific equipment 1

[cptcrogge]

So did it work?

[Djmikke2007]

Is this better than baking in the owen?

[deuzamobile]

Nul! Durée de vie de la réparation....3 minutes!

[valcerfabri]

No Brasil, isso se chama: Gambiarra!

[Officer94]

What the heck are you doing?! O_o

[ukenTV]

OMG

[snakev10v5]

this looks like a good idea to me, but did it do any damage to the compoants? Also wouldn't it be easier to get a solder iron rather than wasting jack? :L

[fernascool]

I did this but exposed the mobo at the fire directly, but first i cover the other components with aluminium paper.

And :D im writing this with my laptop, is a Compaq CQ40 324LA

[Dre4dwolf]

THIS IS A REALLY GOOD IDEA, easier than pencil torch or oven fixes.

[guafito]

brilliant way to cook!

:3

[Vsbreno]

Hey man, i'm from Brazil and i have a t42 notebook with the same gpu problem. How many time i have to let the alcohol burning?

thx

[leonieethan]

Reballing is the only way to go, you should never do this to any electical component, big thumbs down!!!!

[MarcomMrX]

This all thanks to "Lead Free Solder" .....

[1978atcarroll]

@MarcomMrX Yeah. not nearly as many solder whiskers with the older solder. Lead free solder should be used in plumbing & stay the hell away from electronics.

[mofaraider]

too bad this didnt work on my scrap picked T43p with Ati Fire GL, seems to be another sort of soldering, I have also a T41 with the ati 7500 chip with the flexing fault, i will try this also ;)

[Kratermaggi]

Hi! Sorry but I don't understand what is he doing with the notebook... I'm very interested... Please send me a private message and tell me about it... THX

[cadulpr]

@Kratermaggi Voodoo!

[shelbysale]

Doesn`t Work , it works for 2 hours , than the same problem ...

ibm is shit notebooks

[pRoFlT]

I have a dell laptop with this nvidia problem. Maybe i should set it on fire! If not i need to replace the motherboard anyways its out of warranty. what better way then FIRE!!!!

[bonzo999pl]

Woo-doo

[wjli2]

whoa... this is a cheap way of doing it.

[Smokie181]

wth...why risk hundreds of dollars when you can buy reballer kits for cheap...or just take it in to the people with the RIGHT equipment and knowledge

shawnstar86 said it all.

plus are you sure it would align right if this even works?

did you make a whole video?

or did you not even take it off, clean off the old solder and apply new solder balls...did you just light a candle holder full of flammable liquid? lol how do you know your not making it too hot or too long? trippy idea tho

[313EDO]

the reballer is as good as this..I tried already two ways...in both I made a mistake...

here you can't make any mistake... once flamed you have to wait... well I have another notebook with such a problem... so I'll give it a try.

[pomijanlewa]

It re-alligns the BGA balls, isn't it. I have a Nvidia 8600 GS. Do u think it is gonna work for me??

and also

"Screw u nvidia"

[FixedHDD]

yes it will work. But there can also be some heat damage to other components after this method..

[Kegtapper]

The problem is not nVidia. It is the motherboard manufacturing site. Mostly a quality control issue. Many of the boards are made in one place and the chips in another. During that time oxidation is forming on the solderballs so over time when the heat expands and contracts the RoHS solder the balls lose contact. This was not an engineering consideration when moving to Lead-Free solder. Oh Well [MilSpec/NASA Certified]

[wjli2]

nvidia GPU problem is not associated with the BGA solder, it is an internal faulty within the silicon chip of the GPU.

[jamiewalkerowen]

No, the cooling systems in these laptops don't cool the GPU enough, getting up to 100c+ causing the board to expand and contract on cooling which breaks the soldered contacts

[wjli2]

@jamiewalkerowen

Actually after closer investigations by many people in relation to Nvidia media leaks. The problem of Nvidia GPU is due the Eutectic bump material used within the GPU suffering from electromigration when you bump up the current (i.e. playing some GPU intensive games)..... which slowly causes the GPU to fail, you can search this information on google.

[bonzo999pl]

woo-doo

[Aeon333Flux]

@jamiewalkerowen yup this is the correct answer !!!!!

[bibinson]

@wjli2 SOmewhat - I'm fairly sure it's BGA soldering between two layers of the chip package, so it's the same idea just within the chip's substrates itself

[shawnstar86]

you dumb fuck.........

[patozurf]

did this really work

i used reflow in 3 mobos did work well

but in 5 more  those will not work any more!

i mean this work? just heatig the area and not the other ones?
