Patent ID: 7743659

Claim:
A transducer assembly, comprising: a first layer of dielectric material; a pair of electrically conductive traces adjacent to the first dielectric layer, wherein each of the electrically conductive traces include a first contact pad and a second contact pad and wherein the first layer of dielectric material includes a pair of vias formed therein to expose each of the first contact pads; a second layer of dielectric material attached to the first layer of dielectric material with the pair of electrically conductive traces disposed between the first and second layers of dielectric material a pair of holes formed in the second layer of dielectric material; a transducer attached to an opposite side of the second layer of dielectric material from the first layer of dielectric material; and an electrically conductive patch or paste disposed within each of the pair of holes to electrically connect each second contact pad to the electromechanical transducer, wherein the transducer is attached to the second layer of dielectric material to provide a substantially planar surface with the second layer of dielectric material to prevent any voids or steps.
