Problems solved by technology

However, in some application fields, it may only be allowed to open round holes or square slots, but this round hole or square slot structure cannot allow traditional cables to pass through, so designers can only use similar coaxial cables to achieve connection However, the coaxial cable cannot achieve the flexible characteristics of the aforementioned flexible circuit cable. This phenomenon has caused limitations for circuit designers.

Abstract

A flat soft CB structure with a shield plane layer includes an extended insulation field and at least a pair of difference mode signal transmission lines, which is matched in said insulation field inhorizontal intervals and extends from the first end to the second along the extending direction of the insulation field, a shield plane layer is matched on a surface of said transmission line to provide impedance values of the transmission lines. Said shield plane layer can be net one or the one with multiple holing zones, therefore, the difference mode transmission lines are good at signal shieldresult.

Description

technical field [0001] The invention relates to a flexible circuit board structure, in particular to a flat flexible circuit board structure with a shielding plane layer. Background technique [0002] In the circuit design of various electrical devices such as computer equipment, measuring instruments, or control devices, connecting wires, signal cables, or connecting cables are often used to connect different circuit boards, circuit modules, or two or more Electrical devices are connected for electrical signals. For example, in the widely used notebook computers at present, between the mainframe of the notebook computer and the liquid crystal display screen, most of them use flat connecting cables for electrical signal connection, and the signal contact terminals at both ends of the connecting cable respectively connected to the signal connection sockets of the notebook computer host and the liquid crystal display screen. [0003] In logic circuit design that emphasizes h...
