Abstract
A charge plate is fabricated for a continuous ink jet printer print head by applying an etch-stop to one of the opposed sides of an electrically non-conductive substrate. An array of charging channels are etched into the substrate through the etch-stop layer adjacent to predetermined orifice positions. The charging channels are passivated by depositing a dielectric insulator into the charging channels; and electrical leads are formed by coating the passivated charging channels with metal. A second etch-stop layer is applied to the other of the opposed sides of the substrate, and an array of orifices is formed through the orifice plate substrate at the predetermined orifice positions. The orifices extend between the opposed sides.
