Abstract:
A method for making a circuit board comprising the steps of:providing a core member having a first surface and a second surface; attaching a certain first material upon said first surface and upon said second surface, effective to form a first pre-circuit assembly; forming a first aperture within said first pre-circuit assembly; providing a first metal member having a first and a second surface and a second metal member having a first and a second surface; attaching a certain second material to said second surface of said first metal member and to said first surface of said second metal member; applying a certain liner material to said certain second material; engaging said first and second metal members; forming a second aperture through said engaged first and second metal members, through said certain second material, and through said certain liner material; separating said engaged first and second metal members; removing said certain liner material from said certain second material; selectively attaching said certain second material resident upon said first metal member to said certain first material resident upon said first pre-circuit assembly while causing said second aperture which is formed within said first metal member to communicate with said first aperture; selectively attaching said certain second material resident upon said second metal member to said certain material resident upon said first pre-circuit assembly while causing said second aperture which is formed within said first metal member to communicate with said first aperture; selectively removing said certain first and second metal members, effective to form a second pre-circuit assembly; providing third and fourth pre-circuit assemblies; attaching said third and fourth pre-circuit assemblies to said second pre-circuit assembly; and removing certain portions of said third and fourth pre-circuit assemblies, effective to form a third and fourth aperture which respectively communicate with said first and second apertures and which cooperate with said second pre-circuit assembly to form a circuit board having an aperture which extends through the formed circuit board.
