With a solder wick it's very easy (for single sided pcbs only). For double
sided pcb's you need a special tool (desoldering station) but even with such
a tool desoldering can be a problem for double sided pcb's. Fortunately most
of the A-100 modules are single sided.

> a) the old ones
I think it was 370 degrees Celcius

> B) the newer ROHS Boards
we use 425 degrees Celcius (Weller solder tips code "8")
