CHARGE PLATE FABRICATION TECHNIQUE

摘要

A method for fabricating a charge plate for an ink jet printhead entails removing portions of conductive material from a dimensionally stable dielectric substrate (9) with a coating (26) of conductive material to form at least a first and second electrode (27, 28) on a first face (10) with a first space (31) between the first and second electrodes, removing portions of conductive material from the dimensionally stable dielectric substrate with a coating of conductive material to form a first electrode extension (40) that engages the first electrode on the conductive charging face (12), and a second electrode extension (41) that engages the second electrode on the conductive charging face, whereby the first and second electrode extensions are electrically isolated from each other, additionally forming a first space (44) between the electrode extensions, which connects with the first space between the electrode extensions.
