Abstract:
A circuit board comprising:a first electrically conductive member having a first surface, a second surface, and a stepped aperture extending through said first and second surfaces; a first dielectric material which is coupled to said first surface; a second dielectric material which is coupled to said second surface; a first circuit assembly having a second electrically a second dielectric material which is coupled to said second surface; a first circuit assembly having a second electrically conductive member which is coupled to said first dielectric material, said first circuit assembly further including a third electrically conductive member and a first core member which is contained between said second and said third electrically conductive members and which includes at least one air-bridge; and a second circuit assembly having a fourth electrically conductive member which is coupled to said second dielectric material, said second circuit assembly further including a fifth electrically conductive member and a second core member which is contained between said fourth and said fifth electrically conductive members and which includes at least one air-bridge, said second circuit assembly cooperating with said first circuit assembly and with said first and second dielectric material and with said first electrically conductive member to form a multi-layer electric circuit board.
