Abstract:
1. An apparatus that supports a printed circuit board substrate with opposing first and second edges during printing, the apparatus comprising: a first fixing unit including a first movable plate that engages the first edge of the printed circuit board substrate, a first actuator that moves the first movable plate in a first inward direction toward the first edge and a first outward direction away from the first edge, and a first stopper that limits movement of the first movable plate in the first outward direction; and a second fixing unit generally parallel with and spaced apart from the first fixing unit, the second fixing unit including a second movable plate that engages the second edge of the printed circuit board substrate, a second actuator that moves the second movable plate in a second inward direction toward the second edge and a second outward direction away from the second edge, and a second stopper that limits movement of the second movable plate in the second outward direction, wherein when solder paste is printed on the printed circuit board substrate from the first edge to the second edge, the second actuator moves the second movable plate in the second outward direction to contact the second stopper, and the first actuator moves the first movable plate in the first inward direction to press the printed circuit board substrate toward the second movable plate, and when solder paste is printed on the printed circuit board substrate from the second edge to the first edge, the first actuator moves the first movable plate in the first outward direction to contact the first stopper, and the second actuator moves the second movable plate in the second inward direction to press the printed circuit board substrate toward the first movable plate.
