As Graham says, but be aware that unless you are a *very* experienced
solderer, and posess the right desoldering equipment, you will struggle to
do the job. These are some of the very worst bitches to get out of a board,
that you will *ever* come across. And then some.
You should try a Sony 1602 or 1601 IC from one of their broadcast mixer
boards - it can take an hour if you're lucky and all day if you're not
and we have professionaly desoldering vacumme equipment - the holes are
barely larger than the pin its self every engineer working on these
things in every broadcast engineering department complaints about these
devices.. Give me a 100 pin BGA device any day..

If you know the IC's buggered (or even of low commercial value), cut every pin
and remove them individually. Then clean the holes up. It always wins on time and
cost.

sadly that is not an option, the device is a constructed ceramic case of other devices
within with the pins on the underside of the case - rather like a BGA device but pins and
not blobs if you understand what I mean. The board has an exchange value with Sony of
£1050 and they will only accept a board for exchange if not physically damaged, so being
careful and taking time is the only option..
