Abstract
In a method and apparatus for producing an ink jet printer head composed of a number of stacked modules, a piezoactuator plate is formed by metallizing opposite major faces of a plate of piezoelectric material, while leaving an unmetallized stripe on one of said major faces, thereby separating the metallization on that major face into two regions. A side face of the piezoelectric plate is also metallized, the side face extending substantially parallel to the unmetallized stripe, thereby electrically connecting one of the metallized regions on one major face to the metallized layer on the opposite major face. The metallized piezoelectric plate is then structured so as to produce a number of side-by-side piezoactuators therein, each piezoactuator having first and second electrodes formed by the respective metallization on the opposite sides of the plate. Respective electrical leads for the two electrodes of each piezoactuator can be electrically contacted to the same side of the plate, i.e. the side having the non-metallized stripe thereon.
