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 modes a suction plate 2 having small holes 20 is mounted on a supporting body on which a space 30 bigger than the small holes is provided. The holes 20 are connected to the space 30 and to a vacuum device via an air passage 31 and a bottom passage 32. The diameter of the suction hole 20 is so less than 0.4 mm not to make at the printed circuit board such bending that causes exposure troubles.
Claims9
A board stage for an aligner for producing printed circuit boards, comprising;
- a plurality of holes for absorbing the board having an aperture at a surface of the board stage,
- suction means connected to said holes for absorbing the board,
- wherein said holes have such size that does not make at the board such bending that causes exposing troubles when absorbing the board.
