ABSTRACT:
A piezoelectric ink jet print head includes a body of piezoelectric material defining a plurality of parallel open topped channels having electrodes on opposite walls thereof. A top cover having a pattern of parallel conductors congruent with the open tops of the parallel channels is secured to the body by reflow soldering the conductors to the electrodes. The resulting solder bond is very stiff, thereby improving the performance of the print head, and the conductors provide convenient electrical contact to the electrodes.
