Found the main problem During messing around (hopelessly :) we had found the calibration menu and pressed "check". Machine thought that there was a calibration nozzle (maybe 10x10mm square) but in reality, there was d=1.0mm nozzle. Machine decided

You could reduce the paste by about 70%. Solder balling and tombstoning will be the issues to fight. The drivers to these don't change with the component size. Use the fine SMTnet Archives for background. Aperture Size and Thickness of Solder Pas
