Abstract
A novel method of making continuous laminates by irradiation of a continuous sandwich of a radiation curable substrate and a metal foil is described. The method is especially useful for use in conjunction with substrates such as polyethylene in flexible printed circuit applications.
Claims1
A method of making a continuous laminate comprising providing a continuous layer of a radiation curable substrate selected from the group consisting of polyethylene, ethylene/propylene/diene rubber, and polypropylene, said substrate including a layer of stiffener selected from the group consisting of glass cloth, glass mat and glass paper and a continuous layer of copper foil, forming said substrate, said layer of stiffener and said foil into a sandwich, and continuously passing said sandwich through radiation from a radiation source selected from the group consisting of electrons, X-rays and ultraviolet rays.
