68000 PLCC bent pins/contact issues

Post by Pacman »

I've got contact problems with one or multiple pins of my STe's 68000 (U100) PLCC socket.
My first thought is to use a continuity tester (multimeter) between say pin 1 of the CPU and pin 1 of the socket.

Unfortunately there's not enough space to keep the probes apart (I've even tried using two needles attached to crocodile-clips), so what else can I try?

Also, what's the correct/best way to bend a PLCC bend back the way it should be?
