ABSTRACT:
A charge plate for an ink jet printer is fabricated from laminations etched from a thin sheet of corrosive resistant metal. The individual charge electrodes with their respective leads and connecting regions are initially supported in the thin sheet by etched supporting members. Except for the supporting members, the individual charge electrodes with their leads and contact regions are electrically and physically isolated from each other. The lamination sheets are coated with an adhesive, stacked, and bonded together. After filling the open regions in the bonded lamination stack with a structural insulating material, the etched metal supporting members are removed, providing a unitary charge plate that is rugged, dimensionally accurate, and stable.
