FLEXIBLE FLAT CABLE FOR LOW VOLTAGE DIFFERENTIAL SIGNALING

摘要

A flexible flat cable for low voltage differential signaling, includes upper and lower insulating films, and conductive lines interposed between the upper and lower insulating films and arranged at a predetermined pitch in parallel to each other. Each conductive line includes a central part having a circular sectional surface and a rolled part having flat upper and lower surfaces, which are formed by performing a rolling process with respect to an end portion of the central portion, and subject to a heat treatment process, end portions of rolled parts are arranged at a predetermined pitch and exposed to an outside to form a terminal part, a predetermined number of conductive lines interposed between the upper and lower insulating films are grouped in a strip, and a cutting line is formed while passing through the upper insulating film, a space between strips, and the lower insulating film.
