The post about using a metal with lower melting point
triggered a memory, and I confirmed it in our catalogue.

WES components in Australia sells a "SMD desoldering kit"
that is simply flux and a low meltpoint solder. It is
about $18 US. You apply the special solder the the pins,
heat it up with a normal iron and then it stays molten for
quite a while and you can unsolder the whole chip. I don't
know ho many chips it would do. Quite possibly it would
be re-usable??

Sounds smart. I'm sure other suppliers must sell the
kits too, looks like an Asian package.
