Abstract:
A method of manufacturing an orifice plate for a thermal ink jet print head comprising:providing a mandrel with a plating receptive surface; generating a first pattern of orifice elements of a first plating resistant material on the surface; generating a second pattern of strain relief elements of a second plating resistant material on the surface; and progressively plating an orifice plate material onto the mandrel, including covering each of the strain relief elements with orifice plate material, and maintaining at least an exposed portion of each of the orifice elements, such that the orifice plate defines a plurality of orifices and is enclosed at the strain relief elements, wherein generating the orifice elements includes generating elements having a preselected width, and wherein generating the strain relief elements includes generating elongated elements having a width less than the width of the orifice elements.
