Athlon 64 3200+ Pin missing

[davmax]

I have a processor with one pin missing. The pin is not in the socket from which it was pulled.

Seems like a difficult job in the second row from the outside edge.

Has anybody attempted or achieved any success replacing a pin. It looks like it was attached with solder.

Pin has been identified as MEMCHECK(0) PIN U2

Re: Athlon 64 3200+ Pin missing

sounds like micro surgery to me
I guess its possible
I suppose it will really depend on how well the solder will take to the metal and how well you can get the solder to sit without interference.
lastly how temp of cpu may affect it

forum threads I found on it

could find no links on an actual procedure..from a quick search..more just asking the same question.


Hummm thinking about it
if it was a true gold plate on the pins maybe jewelers soldering techniques might be more applicable.
(they mention gold wire in the first link)

interesting problem but not an uncommon one
Sorry Davmax not much help on this one.

oh yeah and pin sounds like one you might actually need

Re: Athlon 64 3200+ Pin missing

Have solved the problem. I inserted a gold plated transistor lead into the socket and cut it off so that in protuded enough with a sharp end so that it imbedded into the solder that attached the original pin. The original pin had simply become detached from its solder, it had not been broken off. Possibly rare.

Thanks for the effort Starfury.

Re: Athlon 64 3200+ Pin missing

so its not soldered?
just relying on pressure to keep contact
I think that sounds safer way to do it ..just got to hope contact remains reliable.
I think it probably will thought.

yeah apparently broken off pins seems to be somewhat common issue common

Good work mate another save from the scrap heap

cheers

Re: Athlon 64 3200+ Pin missing

Yes the pressure is solid , a bit like the modern Intel chips with pressure contact.

Based on this experience if a pin is broken the best procedure would be to heat it with the fine tip of a soldering iron and remove the rest of the pin. Then the pressure pin method can be applied on the solder pad. It is necessary to remove the pin so that the new pressure pin protrudes above the socket by about 1mm and does not disappear inside the socket.
