Abstract: A solderless, direct cable interconnect for an array transducer and method for the fabrication thereof. An ultrasonic array transducer includes an acoustic backing layer, a piezoelectric layer containing an array of piezoelectric elements (typically created from a solid layer of piezoelectric material disposed over a matching layer cut with a dicing saw and fixed on a solid ground plane), and plurality of control wires, disposed between the backing layer and the piezoelectric layer. A solid backing material which will displace slightly at temperature and pressure is formed into the desired shape. Kerfs are precisely cut into the shaped backing material in a pattern such that they will line up with the center of each piezoelectric element in the piezoelectric layer.
