Abstract
An electrographic printhead and a process for assembling same that results in decreased shorting between styli and increased resistance to wear from paper abrasion and further provides high resolution electrographic printing. Each electric circuit board forming the electrographic printhead comprises arrays of wires that are bonded between two stainless steel support bars utilizing an alumina treated face for insulation and molybdenum face for wear resistance.
Claims7
An electrode head assembly for use in electrographic printing comprising a first subassembly of polyimide fiberglass substrate having intimately bonded thereon a plurality of rhodium-plated copper styli;
- a second subassembly comprising at least two metal head bars, each head bar having six faces with a first face of each head bar having a thin layer of molybdenum bonded thereon and a second face of each head bar at right angles to said first face having alumina bonded thereon;
- said first subassembly being sandwiched between the alumina faces of each metal head bar and intimately bonded thereto, thus resulting in said electrode head assembly having the molybdenum coated face as the crown face.
