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