An insulating material, a printed circuit board that utilizes the insulating material, and a method of manufacturing the printed circuit board. The method includes perforating at least one through-hole corresponding with the at least one, which is in correspondence with the via, in a first insulator; applying a surface treatment on the first insulator by irradiating an ion beam; forming a first seed layer over an inner wall of the through-hole and over one or either side of the first insulator; forming a first plating resist over one or either side of the first insulator on which the first seed layer is formed; performing electroplating in correspondence with the circuit pattern and the via; removing the first plating resist; and removing a portion of the first seed layer by flash etching. This method can improve adhesion between the insulator and the circuit patterns to allow fine-line circuit patterns. |
