Bundled flexible flat circuit cable

Abstract

A bundled flexible flat circuit cable includes a flexible substrate that forms at least one cluster section having an end forming at least one first connection section and an opposite end forming at least one second connection section. Both the first and second connection sections or one of the first and second connection sections form a stack structure. The flexible substrate can be of a structure of single-sided or double-sided substrate and may additionally include an electromagnetic shielding layer. A bundling structure is provided to bundle the cluster section at a predetermined location to form a bundled structure. The bundling structure can be made of a shielding material, an insulation material, or a combination of shielding material and insulation material.
