Flexible multi-layered printed circuit cable

Abstract

A thin flexible multi-layered printed circuit cable manufactured by a relatively simple process and having improved electro-magnetic interference and impedance characteristics is described. The cable includes: an insulating substrate layer; a wiring layer formed on the insulated substrate layer; a coating layer laminated on the wiring layer; a first non-woven metal fiber layer laminated on the coating layer; and a second non-woven metal fiber layer laminated on an opposite surface of the substrate layer. Because the cable is coated with a conductive non-woven or woven metal fabric, electromagnetic waves generated during transmission of high speed data are fully shielded. The non-woven or woven fabric having a wide surface area, is soft and can make good surface-to-surface contact.

Dependencies are inferred from the claim text.
