  • Method of manufacturing a curved array ultrasonic transducer assembly
    Patent number: 5044053
    Abstract: A curved array ultrasonic transducer is manufactured by cutting a flat transducer plate, which is attached to a flexible support plate, into a plurality of segments, the segments being hingedly attached by the support plate. The support plate is bent to a radius and the conductive traces in a flexible circuit board are electrically connected to the transducer plate segments. The flexible circuit board, having a plurality of branches, is bent to a perpendicular position such that the traces in the plurality of branches become substantially aligned. The traces exiting the branches are then electrically connected to a pin and socket connector device.
