I inculded the cpu in the photo to help with the difference in color of the metal pins in the adapter I'm asking about. Thanks, Mike
Good question. I've never had one of those either, but it looks kinda cool. Does it have any numbers on it? brand? I read somebody here said a rule of thumb was gold plugs into gold (can't recall who ) and that makes sense, and is also what i've generally seen. What about a year? I've seen older chips also claimed to be "white gold".
"Nextron" is printed on the outside edge. It required a magnifing glass and strong light to see it. Also the inside of the pins(open end) there is what appears to be gold ring on the inside. Weird huh? Mike.
Here's the best photo I can manage. Mike

i'd think it equal to or better than a cpu, you got the slot, and the socket, all rolled into one. If possibly it's white gold, i got the impression that was somehow more valuable, but you might want a second opinion. Also, if you look even closer you might possibly find an identifying number or mark on it somewhere, most likely, as you've already found, along the inner or outer edge
Did you pull that off a board? It loks like you have a cpu and socket to me before the socket would be soldered to the board. Thats why the inside is gold and outside is silver I bet. THats my guess.
PTS, it is part of the load I got a few days ago. I am not sure where it was since I picked up from two difference locations that day before coming home. The one location was from a buyer of a storage locker. She said the owner had been doing computer repair. Mostly what she had was trash. Back to the "socket" like item it does not have any part number on it. Perhaps its an new never installed cpu socket????? Mike.
Thats what it looks like to me.
So I assume it has value but what?
I would say same as connector. $2 a pound?
Thanks. And good advice on that other guys possible big load. GN Mike
Wow! I thought you had pulled it from a machine like that, reading back i'm starting to see it too. Must of been a hek of a repairman to replace that kind of socket, would take some good soldering to do that. That's really cool miked, i've never even seen them sold that way
Bear, thats what had me in the beginning until PTS spoke up. I then was able to recognize it as a new oem part that had never been installed. I think I will just hold on to it for a while.
KZ, I agreee it is most likely silver, I do have a test kit , just don't have a lot of confidence in it, the acids are old.
Thanks to all for the help identifing it, Mike.
I think that was PTS Mike...I'm not nearly as versed in all this high tech garb as you guys are.Quote:

Did I ever mention I'm a little ocd sometimes? After about 3 hours of research I was able to find a very similar product.

Looks to me like the socket part of the pin is likely gold plated, and the pin portion is tin or tin/lead.
Couple other things:
1 - you will almost never find silver coated pins like that. Silver oxidizes too easily which makes it a lousy choice for anything electrical that is exposed to open air. It is used in sealed units like relays, switches, breakers, etc.
2 - I trying to find out what that was made of I came across some pins that are made of nickel or a nickel / boron mix. Just one more possibility to consider in future metal pin id.
Hope that helps some.
Cool! Devo, They've got the plating codes there at the bottom also. Au, Sn or Sn/Pb Also a date for something there at the top 2002
Devo, the reference you provided stated a combination of Pb and Sn was one possiblity. The condition of the pins leads me to think it is likely that it is not just tin. Of course in the in the big scheme of things its not worth much but its been fun looking into it. Mike.
You're right Mike. First off, that's not the data sheet for that particular brand of socket, it was the best I could find for you, but it's a pretty good representation of how a socket like that is made.
The gold portion is obvious on the internal contact area. That data sheet says 30 micron thick plating which is pretty standard from what I have read looking into gold plating thicknesses in general.
The exterior plating according to that data sheet is either gold (which it doesn't look at all like), pure tin 200 microns thick, or a tin lead combination 200 microns thick.
Like you said it really doesn't matter, it will be a gold connector when you sell it. Looking into was just for fun.
Kris Kringle, white gold does look alot like silver, platinum also.
devo had nailed it.
The outer plating of the socket does not need to be gold plated (altough in many cases it does) as it is soldered right into the board, there can be many variations as to the silvery looking plating, in most cases Tin is the main metal composing the alloy.
The pin metals are usually of high ferrous based alloy (such as Kovar) with a thick Nickel overplate (and a Tin alloy plating over it).
The indise hollow part of the pins will always be gold plated as they serve a removable component (CPU) with all the abuse that come along with it.
Kris Kringle, one or both of us has had a complete misunderstanding. I did not take offense to your statement. I was not being a smart mouth in response.
I find in the written correspondence I try but fail to correctly understand what the other person intended all too often.
I wholeheatedly offer my apology. I meant no offense and I hope you can forgive me. Mike
I did attempt to do a pm but the function was blocked. Mike.
