Steve,
You gave excellent soldering instructions, thanks! Those temperatures
work for me, too. Actually, I seldom need to go above my usual setting
400°C (752°F) for Sn-3Ag-0.5Cu. Please notice that the temperatures
given are much above what they specify for the components and FR-4.
This is the temperature of the tool tip for quick (few seconds) and
effective transfer of heat to the solder point. Long time heating of
the solder point to that temperature certainly will damage the PCB and
components.

Here are some conversions  from F to C for the rest of the world:
700°F  371°C
750°F  399°C
800°F  427°C
850°F  454°C
