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.
