DIP socket moss
(1/1)
Alex Eisenhut:
What could this be? This weird growth on just the one pin of a socket... The PCB is for a disk drive for a Commodore 64. Indoor stuff. The board looks fine. Just the ONE pin on the ONE socketed 74LS ... Is it a tardigrade? Or a new kind of mushroom?
amyk:
Looks like dried battery electrolyte - maybe from a previous minor leak?
Cerebus:
Tin whiskers? Certainly looks like them, and electro tin plate isn't uncommon on older sockets.
ChristofferB:
I don't think it's electrolyte leakage. The socket surface below looks shiny, and since there is almost certainly copper and/or nickel present, corrosion damage would have a green/blue tint.

I agree, maybe it's not tin whiskers from the socket, but from whatever DIP IC that was in it.
