Unforunately, I wasn't aware of this previously, and maybe others aren't also...
Among my most prized possions are my first two microprocessors - a pair of Signetics 2650s with ceramic packages and gold plated pins, that I bought new back in 1976.
I dug them out a few months ago, just to make sure that they hadn't been lost, but I didn't take a closer look at them until today.
Not only had the antistatic foam they had been stored in for 40+ years decayed to dust, it had corroded the pins of the chips away in the process. The gold plating was no obstacle.
I found some discussion of this:-
https://vintage-radio.net/forum/showthread.php?t=131907So to save them, (after DeOxiting and cleaning them) I'm thinking of soldering them to machined pin IC sockets like this:-
It looks like the pins on these ceramic packages are not part of the leadframe, but separate pieces that are welded(?) to the frame. I hope they are welded, rather than soldered, so that they won't come adrift when I solder them to the socket.
Before I do this, does anyone here have any better suggestions for saving these chips?
A PCB adapter board with header pins maybe? (they don't need to be plugged into any existing socket, so the pinout can be anything)
