Damage to a motherboards

[murphy7801]

Ok well sold my old rampage extreme 3 to guy at work two days later he returns says that smoke came off of it. Now the edge of the pcb above the ram is missing few layers and is showing the copper underneath I have no idea why any clue anyone ?

Plus he returned it with few bent cpu pins

What a nobber.... Sold as seen I would say

 

[hmmblah]

When I sell parts to people I know I always install it for them. If it's working when I leave it is theirs, no returns. He did something wrong with that board when he installed it.

Well I would normally aswell but he said he was ok I have no idea what he has done to expose the copper like that

i wouldnt be so fast ..........same thing happened to a maximus III extreme board i won here at OC3D

the bent pins are obvious though.....

 

[MaXiMiZe]

That's a shame

Should have told him it's his fault especially as the pins are bent.

No end of drama I have told him.

damn, that layer of pcb must have been scratched off hard to expose copper like that. He also probably don't know how to be careful around a exposed CPU socket if it ain't got no protective cover on it

An awesome board ruined

No its weird it whole strip of PCB missing its not melted in anyway weird I can find no thermal damage

I think he dropped something on the motherboard and caused short circuit!

 

[stevenwright6379]

never known such a thing to happen

known caps and mosfets to blow and smoke but not the PCB its self to come off in such a way

"Yeah my heatsink sort of did a rolly polly and twisted every pin then the fan flew off and took a chunk out just behind my I/O area, all of it's own accord.

Drop it? Who said anything about dropping anything?

"

Probably threw it out of a van and/ or left a dodgy old wire from 5 previous builds dangling there, it scorched the board then when he tried to peel it off that whole top layer lifted away and he realised he was snookered.

maybe a screw or a screwdriver .....!

I'm just guessing!

Or a crowbar

Definitely looks like he got some sort of sharp object and sliced that part of the PCB off, no way it did it all by itself. Plus he broke some pins, suggesting he's not the most 'light handed' guy with computer components.

 

[murphy7801]

Any to conclude Im gonna get ASUS to repair it and bill him for it because its his own damn fault.

 

[Ghosthud1]

It's very well known that if Copper is surrounded by pcb, it can basically evoporate under intense heat. In my picture there was formally a copper lane but was obviously removed.

Oh I dont dispute that and I appreciate the input just there is no other signs of heat no crinkling or anything which perhaps would indicate a short circuit (dont ask how I dread to think) which flash vaporised the PCB layer off with no charring on piece of the PCB with no circuitry of the top and cause the whole board to apparently be non functional (so he says but not gonna test it with bent pins).

Or am I misunderstanding your suggestion (im no expect about damaged to MB Iv never broken or damaged one in my life everything always been fine with me though iv killed few cpus in my time)

I don't know what the traces do, but the 1st picture looks thick enough to be ground. The second one looks like a ground feed to the IC that's sitting just beneath it.

And bent socket pins are perfectly capable of causing it. Sufficient current will vapourise conformal coating, and layers of PCB without any problems at all and that particular point in the trace may present mOhms more resistance than the rest of the trace (notice how it's more or less equally distanced from the two mounting holes which will provide BIG AMPs capability) which is why it went there. I think the same fault has done all the damage it's just the traces that burnt out couldn't handle the current loading and the top screen could.
