Abstract

An ink jet printing machine comprises individual cavit - ts hav,.ig a trans - ucer, a fluid channel, elastomer chute, outer body and ink jet aperture. Each module is generally assembled individually. Production would be greatly improved if the modules could be assembled as batches. A batch process uses a lead frame 3 comprising a strip of ferrous alloy metal with leads 2 for the device extending from one side of the strip. Strip stock, in this form, may be patterned by conventional photofabrication processes, stamping, dye cutting or any other suitable technique. Dimensions of 0.001 inch can be routinely maintained. The final part is then plated with a suitable metal to facilitate lead bonding and minimize corrosion. Typical thicknesses of the lead frame range from about a few thousandths of an inch to 50 thousandths of an inch.
