cpu broken pin

Hi all

I have a T7500 with one broken pin. On the the photos you can see where the pin is and what is his purpose

I have the pin, it's intact, beside of course the fact that it's not on the processor. My question is if I put the pin in the right place of the socket and then put the processor on, will it work? I searched around and found some cases where the processor could work even if one pin is missing, but for what I understand what this pin do, the processor won't work without it.
Another question. If I put the pin, will I be able to pull it out?

 

You need that specific pin for the processor to work.
You can try putting the pin in the socket, and then putting the cpu on top, hopefully it works, but it may not.
I have had this problem once with an old celeron processor. The problem is, when you put the pin into the socket, the pin will migrate to the bottom of the socket. Thus when you put the cpu in, the processor will not touch teh pin, since the pin is all the way at the bottom of the socket. The gap between the socket and the pin is like 1mm.
The best way to fix this, is to get some very thin copper wire, you must make sure that the wire can fit into the whole.
Basically, stick the wire into the socket, and then cut the wire slightly above the plane with which the cpu sits on. That way, the pin you made, is long enough, so that it can migrate to the bottom of the socket, and still be long enough to touch the processor.

Or if you have a good soldering iron, and a steady hand, I would give soldering the pin a shot. It should not be that hard since the pin is on the outside row. If you have never used a soldering iron before, I recommend taking a broken electonic piece and practice soldering and removing solder with the iron. However, once you solder the pin, you need to make sure that the solder does not touch the other pins.
An easy way to avoid this, is some dentistry floss. It is just the right width to fit between the processor rows. Lay about two or three in each row surrounding the pin which you are to solder. Surround teh oin on three sides by floss. This will help prevent the solder from attaching to the other pins.
Once you are done soldering, remove the floss, and then you should be good from there.

Good luck,

Maybe try PCB trace glue instead of solder? I'd try the copperwire in socket method first tough... How did the pin break of? (the socket could be damaged as well)

 

K-TRON what if I put something(like 1mm wire if I can) in the socket to avoid the migration to the bottom? But how come there is a gap?

StefanHamminga the socket is fine for sure.

 

Because if the pins of the CPU would reach the bottom you'd risk bending one or more inserting the cpu (the pins have some tolerance on length, like any other product). Just get some speaker wire or something (quality copper) and use that. Do not use the pin at all when using the wire.

 

Okay, let me describe the socket for you.
The processor has small pins, about 1.5mm long.
The socket needs to be slightly thicker, so that the pins come in contact with the vertical pins in the socket, and not the motherboard. In every hole, their are two or more vertical sets of pins. When you turn the screw on the socket, the top plate rotates a small 1 mm or so, while the bottom part of the socket stays stationary. Because each hole has two or more vertical contacts which go directly from the cpu pin to the processor, the pin does not have to go all of the way down to the pcb which the motherboard is made on.
You can try yourself, if you put the pin into the socket, or stand it next to the side of the socket, you will see that the pin is infact shorter than the socket is high. Therefore if you put the pin into the socket, the pin will migrate to the bottom, and leave a very small gap between the top of the pin and the cpu.

Ok guys thanks for your help, I'm going to buy some AS5 and try to install the processor.
Another thing, does the socket holes has the EXACT thickness as the pins? I'm asking this because the pin has, like head, some leftovers of solder which is definitely.. thicker?(sorry english is not my native language) than the pin. Will this solder be enough to hold the pin?

Btw K-TRON, Is Zalman STG1 any good?

 

I do not know how well the zalman paste ranks up with the arctic silver. I cannot imagine a huge difference. I would stick with the arctic silver, since it pretty renowned, and its so called the best.

It would be good to try and get the wire to be the same thickness as the pin with which it is replacing. I would go by the thickness of the pin, and not the thickness of the head.

K-TRON

 

No, what I meant is, if the 'head' of my pin is larger than the hole of the socket, the pin can't 'fall down' into the socket, right?

 

Yes that is a possibility.

 

oh, I see what you are saying. Yeah you can try that then. If the pin does not fall through, then you shouldnt have any problem. Just put the pin in, and the cpu on top.

Worse comes to worse, all you have to do is a bit of soldering.

Sorry, as I said bad English I WANNA GREEN CARD

 

Done! Working fine for now 42ºC idle.

 

ok... not the pin i wondered about...

THIS FIX IS NOT SUGGESTED FOR ANYONE EVEN atthegates.. I'M JUST SPEAKING OF MY JB WELD ADDICTION


i know an easy way to fix that pin... a product called JB WELD

it's a 2 part epxoy which conducts electricity...(not sure how good it will contuct such low voltages though..

assuming some electrical contact is better than none ,,
and soldering is outta the ? unless you are an electronics god w/ equiptment i've only seen on YOUTUBE...

i'd think about mixing a little bit of the epoxy and placing just enough to coat the bottom of the pin head where it broke from the CPU...
then without unlocking empty CPU socket,, place the pin w/ tiny bit of epoxy in proper hole (should stick way up since socket is locked closed)

next place CPU in socket and the pin w/ epoxy should make contact w/ CPU where it broke off at....

let set 12 hours.... min 24 hrs for full curing of epoxy

BE SURE NOT TO USE TOO MUCH
if it were to blead to adjecent pins then it would malfunction... the epoxy
could be chipped away,, but you'd be risking additional CPU damage...

i'd suggest no thicker than most guides state as thickness for Arctic Silver 5

Yeah this could work. Thanks man

 

hahahah JBweld is awesome, I once fixed a oil pan on a car with it. It started as just a band-aid but it held for many many years.

 

JB WELD RULES... i've patched cracked radiator housings with it,,, fixed many electronics,, just 2 nights ago i used it to glue my brother's MP3 headphones back together...

later,
bigO

 

the pin you are having trouble with is the "ADdress Strobe control" it monitors the fsb speed

if you can't find the answer ASK Hoggie
