   That is the best way at most of the times but much harder to make
because that air has to be slow and "laminar" or the turbulence will cause
cold spots. I have tried to make something like that in a small oven and
gave up in a few days. Easy on a big oven but really hard on small ones,
specially if you want to solder both sides of the board at once. Infrared is
the next best thing and much more easyly done.

Best regards,
