摘要： Disclosed herein are a yoke plate for optical pick-up actuators, a combination structure of a suspension PCB and a yoke plate, and an optical pick-up actuator comprising the structure. The yoke plate comprises a rear yoke at the distal end of one side of the yoke plate, and the rear yoke has damping-gel fillers for attenuating a partial resonance of the suspension wires. The yoke plate is simplified in construction by supporting the suspension PCB using the rear yoke instead of a conventional wire holder, so that assembly process can be simplified and the manufacturing costs can be reduced. The suspension PCB is combined with the yoke plate by bonding or soldering instead of screw fastening, so that the suspension PCB can be combined with the yoke plate without displacement or distortion. The optical pick-up actuator with the combination structure can be provided by a simplified assembly process and reduced manufacturing costs.
