Abstract
A screen printing machine in which a squeegee is driven to form a film of solder on a board through a screen, includes an automatic squeegeeing angle setter which includes a squeegeeing angle adjuster for adjusting a squeegeeing angle of the squeegee and a squeegeeing angle detector for detecting the angle thereof to set the squeegeeing angle of the squeegee by the squeegeeing angle adjuster based on a detection of the squeegeeing angle detector, an automatic pressing amount setter which includes a squeegee pressing amount adjuster for adjusting a squeegee pressing amount caused by the squeegee and a squeegee pressing force detector for detecting a squeegee pressing force to set the pressing amount in consideration of a change in height resulting from a change of the angle of the squeegee by the squeegee pressing amount adjuster based on a detection of the squeegee pressing force detector, and an automatic balancing amount setter which includes a pressing amount balance adjuster for adjusting a balance of the pressing amount of the squeegee to set the balance of the pressing amount of the squeegee by the pressing amount balance adjuster based on a detection of the pressing force detector.
