Abstract

PURPOSE:To uniformly etch an electrically conductive layer by conveying a flexible substrate with a belt conveyor provided with a supporting plate when a resist film is formed on the surface of the substrate and the film is etched by a brush body while supplying a liq. etchant. CONSTITUTION:A conductive layer of copper foil, etc., is formed on the surface of the flexible strip substrate 10 made of plastics, the resist film of a specified pattern is formed on the surface, and to substrate is moved in the direction as shown by the arrow by a belt conveyor 12 continuously moved by a pulley 11. Plural brush bodies 16 fixed to a supporting frame 15 are set on the substrate 10, the respective brush bodies 16 are reciprocated by the supporting frame 15 driven by a driving part 17 in the direction orthogonal to the moving direction of the substrate 10 and circularly moved to follow a small circular locus, and a liq. etchant is supplied onto the substrate from a nozzle 22. The substrate 10 is flattened by the supporting plate 13 under the conveyor 12. The block 20 of each brush body 16 implanted with a fiber body 21 moves up and down along the ruggednesses on the substrate 10 even when the substrate is slightly warped and has some ruggednesses, and hence the part of the conductive layer not coated with the resist film on the flexible substrate having ruggednesses can be uniformly etched.
