Reseating QFP-socketed chips

Anyone else find that QFP-socketed chips in late 80's / early 90's
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!)
