1inch 100W Hot-Plate for SMT reflow

Black Mesa Labs has been using a $20 hot plate for a year now for soldering QFN ICs to PCBs. Only issue so far has been the size ( 10?x10?x3? ) and thermal mass of the thing as it consumes precious microscope work area and unfortunately stays quite hot for 30+ minutes after a quick 4 minute reflow job. BML boards are mostly 1?x1?, so a 800W hot plate with a 6? diameter heating surface is overkill for most jobs.”
