I'll find out when I get the pizzaz.
There are over 300 positive reviews on amazon so it has to bake pretty well.
There were some complaints that it didn't make the edge crisp but it's 12"
diameter so the center so be plenty for most PCBs.
Pizza usually bakes 425F=218C for 15 mins so this unit should be able to
bake most SMD. Both the bottom and the top heat the pizza and you can turn
off either the bottom or the top. The unit uses 1250W so that's quite a bit
of heat.
Rotation keeps the element heating even I guess but I agree in that I don't
see how the temperature stays constant.
$45 is pretty cheap and would be the perfect tool if it works.
Because the top is open, I can hit it with extra hot air from my air gun on
problem areas even in rotation.
I don't think I will be able to push parts around while it is rotating but
you never know that might work too.
