PIEZOELECTRIC PRINTHEAD TRACE LAYOUT

摘要

A piezoelectric printhead trace layout includes an actuator die, bond pads along two side edges of the actuator die, rows of piezoceramic actuators between the two side edges, drive traces emanating from the bond pads toward the center of the actuator die, a ground bus extended along the center of the actuator die between two end edges of the actuator die, and ground traces emanating from the ground bus outward toward the two side edges.
