    摘要: A method of making an ink jet printer channel member for use in ink delivery includes molding piezoelectric ceramic powders into a slab in the green state having top and bottom surfaces, forming alternating grooves on the top and bottom surfaces of the green state slab which provides peaks and valleys in opposite sides of the green state slab, wherein the valleys in the top surface are disposed in an offset relationship to the peaks in the bottom surface, sintering and poling the grooved green state slab; and forming electrically conductive surfaces on the exposed top and bottom surfaces of the sintered state slab. A slot is then cut through the top conductive layer in each of the valleys in the top surface of the grooved sintered green state slab. An orifice plate is positioned over the conductive surface on the top peak surfaces of the slotted sintered slab and a substrate on the conductive surface on the bottom peak surfaces to produce the ink jet printer channel member.
