ABSTRACT:
Multielement ultrasonic probe production process connecting a piezoelectric ceramic block incorporating an upper conductive layer and a lower layer to two printed circuits having a metallized face and a face provided with conductive strips, electrically connecting one of the conductive strips to one of the faces of the printed circuits and the other conductive strip to the other face of said circuits, cutting out said block and the upper part of said circuits so as to form equidistant piezoelectric elements and mechanically insulating them from one another, as well as the connections with respect to each element.
The invention has application to medical echography.
