Abstract
A printed circuit architecture includes a relatively thick, stiffening base of thermally and electrically conductive material, and a laminate of conductive layers including a printed circuit structure, interleaved with dielectric layers, disposed atop the base. The patterned conductive layers contain an integrated circuit structure that is configured to provide RF signaling, microstrip shielding, and digital and analog control signal leads, and DC power. Low inductance electrical connectivity among the conductive layers and also between conductive layers and the base is provided by a plurality of conductive bores. Selected bores are counter-drilled at the RF signaling layer and filled with insulating plugs, which prevent shorting of the RF signal trace layer to ground, during solder reflow connection of leads of circuit components to the RF signaling layer.
