Anyone else find that QFP-socketed chips in late

equipment are *really* prone to corroding and needing re-seating?
I've just had to re-seat several on this NCR Tower which were the
cause of all sorts of problems - yet I don't normally find that DIL
chips need any re-seating on equipment of this sort of age.
(I *think* QFP's the proper name - commonly used for 80186 / 80188 /
80286 chips, which have flat leads underneath the device)
Anyway, I now have a working NCR machine that chucks out more heat
than a small furnace and makes the lights go dim :-) (well, almost!)
QFP's are surface-mount (normally soldered down) devices, and PLCCs are
probably what you're thinking of.
I don't think i've had that problem with any of my machines, but, then
again, I don't have a whole lot of stuff (which I use) that has PLCC
parts in it.
