Is 400 degrees anywhere close to hot enough?

Is 400 degrees anywhere
close to hot enough? from preheat
start to cool down is about 400
seconds with the high temperature
portion less than
200 seconds. See Lattice BGA Solder Reflow and Rework Recommendations
ap note.
Modst BGA part use a lower melting temp material to keep the active
device in the
comfort range (under 250C peak).
The favorite hobby/small shop tool for this is the small counter top
"Toaster Ovens" with an
external temperature control.

I routinely scavenge SMT components from junk boards by heating them in
a toaster oven set to 350F. Components slide right off, so 400F is
probably more than sufficient.

What do you use to store/catalog them, Chuck?
