Replacing a LGA 1151 CPU socket - Is it possible?

[Halcyon]

One of my ham-fisted colleagues decided to have a crack at a brand new motherboard (don't ask) and in the process has done a good job of bending about 10 of the tiny little pins on an LGA 1151 socket. I've tried bending them back into their original positions however because of the spacing, near enough isn't good enough. A few are also bent all out of shape.

Has anyone has any experience replacing these sockets? Can you even buy them as individual components?

Photos attached.

Since you can buy a good Z370 LGA1151 motherboard for right around $100 and know it's good, or a used LGA1151 motherboard in the $50 range, I'd consider a damaged socket BER (beyond economic repair).

Even dual socket 1151s are ~$300 new, $100 used.

This is a server/workstation board. We are looking at over $400 to replace it (and that's cost price).

Did you mean LGA1151 ?

Dropped the CPU on the pins.

They are very fragile and that is what they look like after the accident.

I have tried to fix a few of these with no luck.
Pins sometimes will go back to near perfect looking under microscope and still won't work.

I think the only time you might get lucky is if pin is not connected.

Yes I did. Post amended.

I suspected this might be the case, which is why I would give replacing the whole socket a crack.

You can buy the sockets but replacing BGA is difficult !!

What board do you have?

What board do you have?

Supermicro X11SAE

$221 at Newegg or open box for $180?

One on the UK Ebay site for £266.

You can buy a balled LGA1151 socket for under $10 on Ebay. If this is your first BGA repair, I'd be more inclined to go the NewEgg route...

Look up "replace CPU socket" on YouTube. Plenty of videos. You must use hot air, a soldering iron won't work at all. A preheater from underneath is also useful.

...and better to damage a $200 motherboard than a $2000 CPU.

I have all the required equipment, I'll look at replacing it anyway. At this stage, it's a $400 useless bit of equipment. I can't make it any worse.

Indeed, I can see why they put the pins on the board. Completely agree with the reasoning behind this.

I bent pins in the past but was able to get them back using a magnifying glass and a very fine swiss tweezer.
