基板押え構造。 A vacuum device is placed under a board stand in which a plurality of small holes are drilled, and with a wiring board and a negative or positive photoresist film placed on the board stand, the main body is placed on top of the film. In the vacuum photo printing machine, the photoresist film is printed by pressing a transparent film attached on all sides to a rotatable frame, activating the vacuum device, and irradiating the photoresist film from above. A substrate holding structure for a vacuum photographic printing machine characterized by increasing the thickness of a transparent film concentrically from the center to the outside.
