Abstract: A flexible flat cable contains mainly multiple lines of conductive cable which is elongated to gain better ductility and pressed to change it into a flat cable, encased both on the top and bottom surface with a layer of insulation. The exposed ends of the cable become a section of conductor, on which it is coated with a metal and finally stiffened with reinforcement to become a reliable flexible flat cable. The utmost surface of the conductive ends is further gilt to enhance its conductivity so as to intensify the data transmission efficient when used in LVDS. The purpose of the gilt coating is to harden the cable surface and to restrain the generation of tin tassel from tin coating which would render short circuit in the flat cable.
