OOps, obviously I completely missed what the original
question was, here.

Well, I guess I'll need to build a little convection
tape baker, then. Maybe I'll use something like an
Arduino to control the temperature. I want to build a
toaster oven solder reflow over, too, which might use
the same controller. But operating at a much higher
temperature, of course.
If you can puzzle out German, you might find this article
worth reading. It describes SMD reflow in a toaster
oven, and some of the pitfalls. The main one is that the
temperature sensor needs to be attached to the board, or
to a (blank) copy of that board. If it's attached to
something with a significantly different copper to etch
ratio, it will be heated differently and your board will
either not heat enough, or be overheated -- possibly
enough to scorch it.
