Thick film deposition of microelectronic circuit

摘要

A process for depositing thick film electronic material which forms electric circuits on the inside wall of right circular substrates. The process includes the determination of a circuit pattern wherein a light sensor is used to actuate electronics which in turn controls the flow of the thick film paste for deposition on the substrate inside wall. The substrate is rotated and translated in conjunction with the movement of a light sensor in the x-y plane.
