Abstract:
A pattern of microchannels is formed on a major surface of a substrate on the side opposite an adhesive surface thereof. Through holes extend through the substrate and are connected to the pattern of microchannels. Solid circuit dies are adhesively bonded to the adhesive surface of the substrate. The contact pads of the solid circuit dies at least partially overlie and face the through holes. Electrically conductive channel traces are formed to electrically connect to the solid circuit dies via the through holes.
