Abstract:
The present invention relates to a method of manufacturing a metal clad laminate for printed circuit board, characterized by direct adhesion of a conductive metal foil without use of a thermosetting resin having low melting points, an adherent film or an adhesive. The method includes forming fine protrusions on at least one surface of a fluorine-based resin insulation layer, roughening one surface of a conductive metal foil, laminating the fluorine-based resin insulation layer having fine protrusions on the roughened metal foil so that the roughened surface of the metal foil and the protrusion-formed surface of the insulation layer face each other to form a laminated body, and compressing the laminated body under vacuum, pressure and heat. The method of manufacturing the metal clad laminate by directly adhering the conductive metal foil with a single dielectric structure has advantages in terms of lower manufacturing costs compared to conventional dual dielectric structures, and very stable operation of the metal clad laminate in high frequency regions due to minimized variations of electrical and mechanical properties. Thus, the present method is effective in manufacturing the printed circuit board usable in the high frequency regions.
