steel cpu pins, not the green ones

[Gold Trail]

I have seen many discussions on the steel pins on the green fiber cpu chips.

On a hunch, i put a magnet on the pins of some pentium pro's, regular pentiums and some MMx chips, all of which the magnet stuck.

so the burning question is, if all , or most cpu chips have steel pins, why a different process for the fiber ones, which from what I've read need processed seperatly due to steel in the pins?

Just being magnetic doesn't make them steel. The magnetic pins on the others are probably kovar = 54Fe, 29Ni, 17Co.

As I was corrected by OEF62ND by PM I ment iron pins, not steel. Although the last time i check, steel is an alloy made mostly of Iron. I am sure there are thousands of alloys out there with iron in them.

And except for my gold refining, none of the other steel or iron alloys concern me.

GSP, thank you for your post, i knew the ones were a different alloy, but was caught both by surprise and off guard when the magnet stuck to all cpu pins. not just specific types and may have jumped to conclusions.
