Abstract
A screen printing method and apparatus are capable of maintaining a constant attack angle between a squeegee and a mask plate, regardless of the surface condition of the mask plate. A squeegee head, including a pair of squeegees, is rotatably supported by a retainer with respect to a horizontal axis that is at a right angle to a squeegeeing direction. The rotatably supported squeegee head is pushed by a cylinder against the mask plate. Accordingly, the attack angle is kept constant to improve the printing quality even if a substrate has a curved portion.
