PURPOSE:To make it possible to give a desired function to a double side copper-clad laminated board and to contrive the improvement of productivity of the laminated board by a method wherein a prepreg or prepregs with a functional resin layer formed on the surface, which is situated on the side of each copper foil, of each prepreg and a copper foil or copper foils with a functional resin layer formed on the surface, which is situated on the side of each prepreg, of each copper foil are used in the manufacture of the laminated board. CONSTITUTION:In the case of the manufacture of a double side copper-clad laminated board obtained by a method wherein one surface of one sheet of a long prepreg or each one surface of a plurality of sheets of long prepregs is superposed on a long copper foil or is alternately superposed on long copper foils to introduce the prepreg and the copper foil or the prepregs and the copper foils in a continuous press and the prepreg and the copper foil or the prepregs and the copper foils are continuously laminated and molded, the prepreg or the prepregs with a functional resin layer formed on the surface, which is situated on the side of each copper foil, of each prepreg and the copper foil or the copper foils with a functional resin layer formed on the surface, which is situated on the side of each prepreg, of each copper foil are used. As a method of forming the functional resin layer, a method, wherein a functional resin composition is adjusted and this is applied on one surface of each prepreg or the rear of each copper foil by a roll coating, a spray coating and other means and is heated and dried according to the need, is exemplified. Thereby, it becomes possible to manufacture the laminated board with the functional layers very efficiently. |
