PURPOSE: To carry out a double-sided coating with a liquid resist by equipping a measure to spray and dry liquid onto a surface of a substrate while being conveyed to a conveying direction and a measure to parpendicularly rotate the substrate.
CONSTITUTION: A substrate (20) being positioned on No.1 belt-type conveyor (3a) is conveyed to below a dynamic air pressure box (13) being positioned in No.3 conveying line IC. The substrate for a printed circuit board (20) to be coated both sides is positioned on a paper web. The substrate(20) is conveyed from the paper web to a heat resistant conveyor belt (2), then, transmitted onto the belt-type conveyor (3a) and further transmitted onto a drilling conveyor belt (4). The substrate (20) is further transmitted by a paper web(39) to a drying chamber and conveyed while being placed on a air cushion (8) to a storage tray (19). Coating is thus carried out effectively.
