Abstract
A novel method to manufacture a flexible cable for a disk drive is disclosed. The method includes providing a flexible laminar sheet. The flexible laminar sheet has a dielectric substrate layer and an electrically conductive layer contacting a first side of the dielectric substrate layer. A portion of the electrically conductive layer is etched away to define a first plurality of electrically conductive traces and to expose an etched surface of the first side of the dielectric substrate layer. A second plurality of electrically conductive traces is deposited on the etched surface of the first side of the dielectric substrate layer.
