Abstract:
A screen-printing apparatus comprising:(a) a substrate-positioning means for positioning a substrate relative to a screen mask having pattern openings; (b) a three-dimensional-measuring means for measuring three-dimensionally an object to be measured within a range including said substrate-positioning means and a mounting section of the screen mask; (c) a moving means for moving said three-dimensional-measuring means; (d) an origin-determining means for setting an origin on a control program by identifying a position of predetermined measuring point on the object to be measured with respect to an origin of a mechanical-coordinate system of said screen-printing apparatus based on a result measured by said three-dimensional measuring means; wherein said apparatus prints paste on the substrate through the pattern openings by attaching the screen mask to the substrate and sliding a squeegee head on the screen mask.
