Abstract
A board stage of an aligner that can avoid bending of a printed circuit board to be exposed and accomplish high accurate exposure. In one preferred mode a suction plate having small holes is mounted on a supporting body on which a space bigger than the small holes is provided. The holes are connected to the space and to a vacuum device via an air passage and a bottom passage . The diameter of the suction hole is so less than 0.4 mm not to make at the printed circuit board such bending that causes exposure troubles.
