I have two Mac logic boards (an LC and a Quadra 700) which came
to me after the PRAM batteries had exploded, leaving a pretty
awful mess. The good news is that there doesn't seem to be any
permanent trace damage, and none of the surrounding parts were
blown away except for a cheap, easily-replaced SMT diode.
However, the last bits of the terminals for the battery holders
are still in the holes. With careful application of abrasives
and solvent, I managed to clean them to shiny metal, but they're
resisting desoldering pretty well (they seem to be mostly rust
or similar corroded detritus at this point).
Anyone have tips on removing corroded battery terminals from a
PCB?
