METHOD FOR MANUFACTURING ULTRASOUND TRANSDUCER

摘要

A method for manufacturing an ultrasound transducer according to the present invention includes a first step of manufacturing a wiring layer by arranging insulating fibers on conductive threads, a second step of electrically connecting one end of the plurality of conductive threads to a transducer array unit, a third step of providing a first backing material after providing a second backing material so that at least connection sites between the transducer array unit and the conductive threads are embedded, and a fourth step of curing the first backing material so as to fix the transducer array unit and the wiring layer.

1. A method for manufacturing an ultrasound transducer, comprising:
a first step of manufacturing a wiring layer with insulating fibers arranged on a plurality of conductive threads to hold the conductive threads spaced apart from each other by a predetermined distance; a second step of electrically connecting one end of the plurality of conductive threads to a transducer array unit having a plurality of electrodes provided on an acoustic radiation face that radiates ultrasound and on a rear side of the acoustic radiation face; a third step of providing a fluid and curable first backing material that attenuates unnecessary ultrasound after providing a rigid second backing material that attenuates unnecessary ultrasound so that at least connection sites between the transducer array unit and the conductive threads are embedded; and a fourth step of curing the first backing material so as to fix the transducer array unit and the wiring layer.
