ABSTRACT:
A flexible printed circuit for electrically connecting a disk tray to a chassis of an optical disk drive has a base layer, a copper layer, and a cover layer. The copper layer is attached to the base layer by a first adhesive layer, and has a plurality of separate electrical wires and a ground area. The cover layer has a cutout area corresponding to the ground area, and is attached to the copper layer by a second adhesive layer. A third adhesive layer is electrically conductive and used for attaching the cover layer to the chassis of the optical disk drive. Wherein the third adhesive layer is electrically connected to the ground area of the copper layer through the cutout area, the static charges accumulated on the copper layer will be discharged to the chassis.
