Abstract:
Process for manufacturing an acoustic probe comprising a matrix of M.times.N piezoelectric elements distributed on the surface of an acoustic attenuation layer, the said elements being connected to an electronic device for controlling and processing the signal via an interconnection system, characterized in that the production of the interconnection system comprises the following steps:producing M dielectric substrates on each of which are produced N conducting tracks and a window in which the conducting tracks are locally left bare;stacking the M dielectric substrates, leading to the formation of a cavity corresponding to the stack of the M windows;filling the preformed cavity with an electrically insulating, acoustically absorbent material;cutting the stack of the M dielectric substrates in a plane lying within the cavity filled with insulating, acoustically absorbent material.
