1. A piezoelectric assembly comprising:

  • an electrode assembly including;

    a first electrode, a second electrode, and a piezoelectric material in electrical communication with each one of the first and second electrodes and being disposable in an electric field generated between the first and second electrodes, wherein the piezoelectric material is provided in an un actuated state in the absence of the generated electric field and is provided in an actuated state in the presence of the generated electric field;

    a metal shim supporting the electrode assembly and being electrically connected to one of the first electrode and the second electrode;

    a printed circuit board including a trace, the printed circuit board having a first side surface and an opposite second side surface, and a passage provided between the first side surface and the second side surface;

    the passage being a plated drill hole;

    an interconnecting structure effecting electrical communication between the trace and the metal shim wherein the interconnecting structure being disposed within the passage of the printed circuit board; and

    extending through the first side surface of the printed circuit board to provide a coupling structure coupled to the metal shim at a coupling structure surface interface, and the interconnecting structure also extending through the second side surface of the printed circuit board to provide a retainer disposed in opposition to the second side surface.
