An assembly is provided which includes a first circuit panel having a top
surface, a first dielectric element and first conductive traces disposed
on the first dielectric element. In addition, a second circuit panel has
a bottom surface, a second dielectric element and second conductive
traces disposed on the second dielectric element, where at least a
portion of the second circuit panel overlies at least a portion of the
first circuit panel. The assembly further includes an interconnect
circuit panel having a third dielectric element which has a front
surface, a rear surface opposite the front surface, a top end extending
between the front and rear surfaces, a bottom end extending between the
front and rear surfaces, and a plurality of interconnect traces disposed
on the dielectric element. The bottom end of the interconnect element
abuts the top surface of the first circuit panel and the top end abuts
the bottom surface of the second circuit panel, where at least some of
the first conductive traces are in conductive communication with the
second conductive traces through the interconnect traces.
