<p>A wide-array inkjet printhead assembly (12) includes a carrier (30) and a plurality of printhead dies (40) mounted on the carrier. The carrier includes a plurality of conductive layers (34), a plurality of conductive vias (38), and a plurality of insulative layers (36). The conductive layers include a first interface layer (70/170/270) disposed on a first face (321) of the carrier, a second interface layer (71/171/271) disposed on a second face (322) of the carrier, and at least one power layer (72/172/272,273), data layer (76,78/176,177,178,179/277,278, 279), and ground layer (74,75/174,175/274,275,276) each interposed between the first and second interface layers. Each conductive via provides a conductive path through at least one of the insulative layers to provide electrical coupling between selected ones of the conductive layers, and each of the printhead dies are electrically coupled to the first interface layer. <IMAGE></p> |
