Claim:
1. An ultrasonic transducer assembly comprising: a transducer array comprising a number of spaced transducer elements; at least one printed flex circuit including two or more overlaid stepped trace layers, each trace layer having a plurality of conductive traces therein the ends of which are electrically coupled to a corresponding transducer element, wherein alternating ends of the conductive traces in the overlaid trace layers are spaced at different distances from the transducer elements and wherein the distance between traces in any single trace layer at a point where the traces are coupled to the transducer elements are spaced farther apart than a distance between adjacent transducer elements in the transducer array; and a plurality of interconnections, each interconnection electrically coupling a conductive trace in a trace layer of the printed flex circuit to a corresponding transducer element.
