Abstract
A process relating to the manufacture of medical echograph probes for establishing a network of connections to elementary transducer units. The process includes the steps of cutting transducer units from a piezoelectric plate, drilling holes in a polymer film on the piezoelectric plate by means of a photoablation process or a reactive ion plasma etching process, and making connections by metallization and then etching to form conducting tracks which connect to the piezoelectric layer via the drilled holes.
