Abstract:
1. A method for making a circuit board, said method comprising the steps of: providing an electrically conductive core member having at least one aperture traversing from a top surface to a bottom surface of said electrically conductive core member; applying a layer of a first dielectric material to said top surface and said bottom surface while leaving said at least one aperture exposed; applying a separate second dielectric material upon said exposed at least one aperture, thereby forming a first pre-circuit assembly having a core member with said first dielectric material upon said top surface and said bottom surface and said second dielectric material within said at least one aperture; applying a pair of layers of adhesive to said first pre-circuit assembly, wherein said layers of adhesive material have at least one aperture which corresponds to said at least one aperture in said core assembly; providing a pair of electrically conductive members; coupling said pair of conductive members to said first pre-circuit assembly to substantially cover said at least one aperture; and removing at least one portion of said pair of conductive members which covers said at least one aperture.
