If I Put A brocken CPU Pin Back Into the socket will it work?

Question

Like I said If I Put A brocken CPU Pin Back Into the socket will it work? If not who would be able to fix it? Thanks

Hi there !
Yes, you can fix a broken pin on a CPU, -- I do it all the time.
Just putting the pin back in the Zero Insertion Force holder, and then putting the CPU on top would only work IFF you had a longer pin than normal, bottomed out the pin so that it stuck up exactly the correct height, and carefully applied pressure on the CPU to make a touch connection. This type of connection would be subject to failure from heat expansion, vibration, and electrolytic corrosion on the touch joint contact point - but, in the short run, it would work.
I solder the pin back onto the CPU. Usually I take a piece of single strand copper wire the EXACT same size as the pin diameter, and bend an exact 90 degree angle in the wire. I hold on to the flat part of the wire that runs parallel with the bottom of the CPU, so that I have something to position the post with, while soldering. The original pins are not soldered usually, but " spot welded" onto the substrate contacts. If you look at a CPU wiring diagram, you can cheat a bit if you are lucky - many pins are duplicates, and depending on which pin broke, there may be a duplicate pin next to it, or nearby, and you can snake the wire, flat against the CPU bottom, around the good pin, over to where the missing pin is, and solder the wire to the good pin FIRST, which helps to hold it in place. Then you must use a VERY sharp, thin soldering tip, usually gas powered, to put a tiny solder dot on the area where the broken pin was, to connect to the new wire.
If there are no other usable pins close to the broken pin, I usually make a zig- zag of bends on the section of the wire parallel to the CPU bottom, between other pins, and have the bent end over top of the missing pin. Again, you solder the 90 degree bend to the dot on the CPU bottom, where the missing pin broke off. I then use glue to affix the zig- zag to the bottom of the CPU, for support, since the solder dot on the CPU is not strong enough to hold the new copper pin in place. THEN, I use very precise side cutters to cut off the excess wire that I would use to hold on to, while soldering. On most CPUs, the CPU does NOT sit flat on the ZIF solcket, so that there is room for the zig- zag of flat wire on the bottom of the CPU. If the wire does raise the CPU a tiny bit, this usually does not interfere with anything as well, since there is a certain amount of spring or variance in the Heatsink clips.
As far as I know, I am the only person I have heard of on any Technical forum I have ever viewed who solders broken CPU pins back on, but I have heard of really professional SMT and repair facilities that USED to do this. No one does this anymore, since the price of the CPUs has dropped so low that an expert with SMT and spot welding equipment, at $80 to $120 an hour, is more expensive to hire, than just buying a new chip.
((( NOTE: I just stumbled across a QUESTION from a user called maytag, who had the identical question to you, including the bad spelling, which makes me think that you signed up under a new name, and posted the same question.... You would know that
motherboardreapair.com will repair CPU pins for $35 plus plus, which, for an expensive CPU is well worth it. HOW [e-mail] actually repairs the CPU pins, I don't know, but the fact that he repairs motherboards indicates that he has equipment that is better than most computer repair shops, who usually just throw out motherboards that have problems. If you indeed are maytag, then your previous questions, like "I have 8 bent pins" and " what happens if I put a bent pin on CPU in socket" etc. indicate that you broke a pin off trying to straighten it.
A previous ANSWER correctly states that you need long nosed, thin, precision needle-nosed pliers to properly bend back pins.
I would guess that if you could not bend back a pin straight, without breaking it, that you are not co-ordinated einough to do the pin replacement, that I describe here, and I suggest you have someone who does micro soldering give it a try, or that you use motherboardrepair.com -- If you are NOT the user, maytag, then there is an amazing co-incidence! You should look up the answers that he got.. )))
If you know anyone who does reasonably precise soldering, particularly on smaller electronics, using gas powered soldering guns, they can probably follow my instructions to put back a pin.
If you have good eye-hand co-ordination, and are adventurous, you can get a butane soldering gun and thin tips at any electronics store, as well as the thin electrical paste solder, and side cutters, and try it yourself. For glue, you get two tubes of binary, 5 minute epoxy, mix it when ready on a piece of paper, and use a toothpick to apply it to the zig- zag. In 5 minutes it is done.
The most pins on a single CPU I have done, is 3. You put the CPU in, and try to never touch it again! -- But it does work..
Bending the Zig zags, aligning the pin, soldering, and gluing takes patience. But it is just a mechanical thing. Nothing special is required, nor any special knowledge.
The most common cause of broken pins is not actual broken pins ( say the CPU is dropped), but people who do NOT take care bending back the pins who break them off trying to straigten them! If you have bent pins, no matter HOW bent they are, you can usually straighten them ONCE. Use very thin, long, precision pliers, and gently straighten them. Try to put the pliers from the top of the pin to the bottom on pins which are bent in the middle. Dont grab the end of the pin and try to straighten a kink in the middle. Being very slow and careful really is the most important aspect.

good luck

Answer 2

Are you talking about the pin on the CPU chip?
If so, two things..

First, what did you do!?

Second, I don't think so.

Not very helpful, am I?
