Abstract
A screen printing apparatus prints cream solder through a pattern hole of a mask plate, to which a substrate is brought into contact, by sliding a squeegee head. A three dimensional detector, such as a laser, is used to determine the extent to which the pattern hole is filled with the cream solder. Based on the determination result, the printing operation is modified, with respect to the positioning of the mask plate and substrate, to maintain the printing quality.
