Abstract:
Disclosed is a flexible circuit cable with at least two bundled wire groups. The circuit cable has first and second ends respectively connected to first and second connection sections. The circuit cable includes a cluster section, which is formed of a plurality of cluster wires formed by slitting the circuit cable, in an extension direction of the cable, at a predetermined cut width. The cluster section includes at least two independent bundles, which are formed by dividing the cluster wires of the circuit cable into different signal groups according to electrical signals transmitted therethrough. Bundling members are used to the cluster wires of the independent bundles according to predetermined bundling modes. Further, the circuit cable has a surface forming a shielding conductive layer for electromagnetic interference protection and impedance control for internal signals of the 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.
Abstract:
A multilayer stacked circuit arrangement with localized separation section, has a first flat cable and first signal transmission lines arranged on the first flat cable. A second flat cable is stacked on and bonded to the first flat cable. The second flat cable further has signal transmission lines arranged on it. A bonding substance layer is formed between a first non-separation section of the first flat cable and a second non-separation section of the second flat cable for properly stacking the first and second flat cables where the separation sections are spaced apart from each other. A conductive via extends between the first non-separation section and the second non-separation section. At least some of the second signal transmission lines of the second flat cable are connected through the conductive via to the first signal transmission lines of the first flat cable.
Abstract:
A composite circuit board with fracturable structure includes a first flat cable and first signal transmission lines formed on the first flat cable. A second flat cable is stacked on and bonded to the first circuit flat cable. The second flat cable includes second signal transmission lines and forms an overlapping segment and a selective breakable segment between which a fracturable structure is formed. The selective breakable segment covers the connection segment of the first flat cable or may be broken off for separation of the flat cables. Some of the second signal transmission lines of the second flat cable are connected through a hole in the first circuit flat cable to the first signal transmission lines of the first flat cable or connected through the hole to the conductive terminals of the connection segment of the first flat cable.
Abstract:
Disclosed is a detachment and displacement protection structure for insertion of flexible circuit flat cable. An inserter positioning section is formed on a flexible circuit flat cable and coupled with an inserter, which includes a metal member and a plastic member. In assembling, the plastic member is first positioned on a first surface of the inserter positioning section of the flexible circuit flat cable, and then the metal member is fit over the plastic member. A detachment and displacement protection structure is provided on the inserter positioning section to constrain the inserter from displacing and detaching in a flat cable extension direction due to being acted upon by an external force when the inserter is positioned on the inserter positioning section.
Abstract:
A rigid-flex PCB includes at least one rigid PCB (RPCB) and at least one flexible PCB (FPCB). Each RPCB has a connection section; first and second sections separately extended from two lateral edges of the connection section and having at least one FPCB bonding side each; and a weakening structure formed along each joint of the connection section and the first and second sections. Each FPCB has a bending section corresponding to the connection section on the RPCB; first and second sections separately extended from two lateral edges of the bending section and having at least one RPCB bonding side each corresponding to the FPCB bonding sides of the first and second sections of the RPCB. When a proper pressure is applied against the weakening structures, the RPCB may be easily bent broken at the weakening structures to remove the connection section therefrom.

Abstract:
A flexible circuit board with specific shielding planes is used for low voltage differential transmission mode circuits. Both the impedance and the transmission time for the transmission line in the circuit board is controlled by shielding planes with varied void opening patterns. Capacitance and slow wave effects related to the combination of void opening patterns and the location configuration related to locations of void opening patterns are used to improve the impedance and transmission timing for the transmission line in the circuit board.
