The big problem is that the ground terminal

to another known ground point, but I'd like to avoid that
approach if possible.
Use enough heat--those inner ground-plane connections will suck the
soul out of a standard 40W TC iron. As others have mentioned, add
solder to it while you work.
Right - I have enough desoldering experience to know to keep
it wet (it's more intuitive than you might think, as molten
lead is a much better heat carrier than a point contact). I
guess it's getting about time for me to upgrade from the 30W
Weller fire-starter I've been using for years, though.
I guess most of my question boils down to the fact that the
pins seem to have corroded all the way through, so I didn't
think they'd be particularly amenable to conventional
extraction. CAIG Flux-Off seems to do fairly well for
removing the worst of the corrosion once sufficiently abraded,
but I suppose DeOx-It would be a better candidate if I had any.
