Double-side-conducting flexible-circuit flat cable with cluster section

A double-side-conducting flexible-circuit flat cable, comprising:

• a flexible circuit substrate, which has a first surface and a second surface, the flexible circuit substrate comprising, in an extension direction, a first double sided golden fingers connection section, a plurality of single sided second golden fingers connection sections, and a cluster section connected between the first connection section and the second connection sections, the cluster section being composed of a plurality of clustered flat cable components formed by slitting in the extension direction;
• a first electrical conduction path, which is formed on a first portion of the first surface of the flexible circuit substrate and extending along one of the clustered flat cable components of the cluster section;
• a second electrical conduction path, which is formed on a second portion of the second surface of the flexible circuit substrate and extending along one of the clustered flat cable components of the cluster section;
• a plurality of first conductive contact zones, which is arranged on the first surface of the flexible circuit substrate at the first double sided golden fingers connection section to be spaced from each other, each of the first conductive contact zones extending along one of the electrical conduction paths of the cluster section toward the plurality of single sided golden fingers second connection section;
• and,
• a plurality of second conductive contact zones, which is arranged on the second surface of the flexible circuit substrate at the first double sided golden fingers connection section to be spaced from each other, each of the second conductive contact zones extending along one of the electrical conduction paths of the cluster section toward the plurality of single sided golden fingers second connection section.
