Liquid Metal Thermal Paste + Alienware = KO

[magneh]

Hey guys !

Funny one to share.
What would be an IC replacement due to conductive thermal paste, revealed to be something more...
Long story short, owner contacted for burned IC due to thermal paste accident, and when I put my eyes on it ... sweet god!
Theres this liquid thermal paste everywhere under the chips... GPU, ram ic's...
So sad...

Someone had some kind of similar case?
Can this be blown off with compressed air or something? or only way is lifting the BGA's?
I can lift the ram chips and reball, but I dont have BGA machine for the GPU for ex.

Photos for some fun!

What a mess!
ahahah

poor machine. its the 2018 model, 1070 and i7

Thanks for any inputs!

Re: Liquid Metal Thermal Paste + Alienware = KO

how much he put in it ? i see video of how to apply it and u need to stick some quantity both gpu and heatsink... not only gpy to make it stick btter and not flow away, then suck all the excessive quantity.clean whole board , replace that burnd component and hope it wil work again

good luck

ps: i think there is some liquid solution to make that liquid thermal get away in an easier way eithout the need to reball every single chip... more u work on the board ( reballing reflow) more u can get trouble.

Well it flew everywhere...
What worries me the most is the part under the gpu...tried to remove it with tweezers and alcohol...not good enough...its really sticked under it.

I wont do BGA reballing as I dont have the station, so Im debating if I should even try something...or just give it back to the owner.

What would be the liquid to clean this? The owner sent an email to the thermal paste support , but still no feedback.

What a mess

yeah. too messy for me.

hand it over to the owner with no repair.

That sh#$ was everywhere under the chips.

Next!
