Hi ,
I just invest in a new "Plancha Grill" from TEFAL with removable plate (Die cast aluminium plate).
The choice of this one, better than a standard oven, is you can replace very easy your components in live, with a good view in case you used too much solder paste and the components move.
Also the resistor offers a real heat diffused in all surface and not just around the plate as we can found in standard grill plates.
The results today are perfect compared to my old grill plate.
The second thing, personally for solder paste, i use a "dispenser tool" ( from Teli Dispensing Asia), where i can manage exactly the solder paste points and i used it also for silicone dispenser. (needs a small external air compressor, to use with).
My conclusion, as now more and more devices uses SMD components, we need to adapt our tools for that, specially if you want to build your units yourself.
Cheers, Henri
