FIGS. 7A and 7B are a perspective and a side view, respectively, of the dielectric substrate, the thin conductive laminate and the thick conductive laminate of FIGS. 5A and 5B, showing a layer of resist patterned upon both the thick conductive laminate and the thin conductive laminate so as to define the interconnects to be formed from the thick conductive laminate and the conductive traces to be
