SCREEN PRINTING DEVICE MASK OVERLAP MOUNTING METHOD, AND SCREEN PRINTING DEVICE

摘要

A screen printing device comprises a mask (7) having a printing opening, and a substrate support unit (3) holding a substrate (W) which is a printing subject movably with respect to the mask (7). Printing is effected with the overlapping of the substrate (W) and the masks (7) effected by the operation of the substrate support unit (3). Prior to the overlapping of the mask (7) and the substrate (W), a circuit pattern on the substrate (W) and the printing opening in the mask (7) corresponding to this pattern are imaged, and a deviation (positional error) between the circuit pattern and the printing opening is found on the basis of these image data. On the basis of this deviation is effected the overlapping of the mask (7) and the substrate (W) by control-driving the substrate support unit (3).
