And coating the insulating resin layer on the outer surface of the two copper foil layers, and applying the liquid photosensitive green paint to the two copper foils through the processing operations of screen printing, curtain coating or electrostatic spraying On the resin layer of the outer surface of the layer, the copper foil layer is dried and then cooled, and subjected to an exposure operation in an ultraviolet exposure machine, for the green paint to produce a polymerization effect after ultraviolet irradiation to form a coating film, and carbonic acid is used. The sodium aqueous solution is used to develop and remove the unexposed area of the coating film, and the high temperature baking operation can be utilized to harden and form the resin contained in the green paint on the outer surface of the copper foil layer.
