ABSTRACT:
A charge electrode structure for an ink jet printer comprises a plurality of electrodes and connecting circuit leads embedded into a molded dielectric substrate and anchored thereinto by means of an embedded depth that exceeds the width of the electrodes at the surface of the substrate. The charge plate is formed by means of photolithographic, plating and molding techniques. Nickel electrodes and circuit leads are plated through a position defining pattern in a photoresistive covering onto a copper foil sheet to a height slightly exceeding the photoresistive covering to form retaining flanges. The photoresistive covering is then removed and the composite foil sheet/plating is bent toward the plating such that the electrodes extend at approximately a 90.degree. angle relative to the remainder of the sheet. The bent composite is then placed into a mold and a dielectric substrate is formed to engage and surround the electrodes and circuit leads. After curing, the substrate with the embedded circuit leads and electrodes is removed from the mold, and it is placed in a copper etchant to remove the copper foil sheet thereby exposing the charge surface and the conducting circuit path surface of the molded charge plate substrate.
