All depends on the part, data sheets contain that information.
e.g. they might say, hand solder 700°F for 9 seconds max
some might specify a rest time.
the key is to be quick about the solderi

two rules,
you have to add solder to desolder ( by hand )
if you don't need the part get out the cutting tools :-)

Future warning, don't do that to an old carbide tipped blade.
The braising holding on the carbide might be a touch brittle, and
cause a few teeth to launch.
Welcome to the world of toolmaking :-)
on a side note, a diamond saw blade probably wouldn't do what you
want. They are not designed

Bert,
just a question about the shell style globs for the filters.
you are adding two of the posable capitalizations
+gtk_file_filter_add_pattern (pcb_filter, "*.pcb");
+gtk_file_filter_add_pattern (pcb_filter, "*.PCB");
Will gtk's globs use the following syntax?
