SCREEN PRINTING APPARATUS AND SCREEN PRINTING METHOD

摘要

In a screen printing apparatus for contacting a lower surface of a mask plate (12) with a substrate (6) and moving a squeezee (16) in a sliding motion on an upper surface of the mask plate (12) thereby printing a paste onto the substrate, mask bend preventing members (117) are mounted on conveying rails (7) at front and rear parts of clamp members (8) clamping the substrate (6) in a Y-direction, and, at a mask separating operation after printing, the substrate is lowered while the lower surface of the mask plate (12) is supported by the clamp members (8) and the mask bend preventing members (117). Thus the mask separation can be achieved in a state where the mask plate (12) is supported from below on four sides of the substrate (6) and is thus prevented from a downward bending, and a satisfactory mask separating property can be ensured over the entire substrate (6).
