Abstract:
A screen-printing apparatus for printing paste on a substrate through pattern openings of a screen mask by attaching the screen mask to the substrate and sliding a squeegee head on the screen mask, comprising:(a) a substrate-positioning means for positioning the substrate relative to the screen mask having the pattern openings; (b) a three-dimensional-measuring means for measuring three-dimensionally a top surface of the screen mask at a printing position and a top surface of the substrate at a measuring position of the substrate; (c) a moving means for moving said three-dimensional-measuring means; (d) an inspecting means for inspecting at least one of the substrate and the screen mask based on a result of measurement by said three-dimensional-measuring means, wherein the inspecting means includes a supply-material-determining section for determining pass or fail of at least one of the screen mask and the substrate, wherein the inspecting means includes a print-determining section for determining pass or fail of the printing result of the substrate; and (e) a touch-up means for touching up a print-failure part of the substrate determined to be print failure by said print-determining section.
