Problems solved by technology

[0003] As shown in CN101494096A, a plurality of wires arranged in parallel can usually be arranged in the flexible cable according to actual needs, and the distance between the wires is small; although such an arrangement can make the connection convenient and reduce the volume of the electronic product, the parallel wires The noise between them will superimpose each other, which may interfere with the data transmission in the wire; in addition, when the flat flexible cable transmits signals, it will generate relatively high-frequency electromagnetic waves, which will also cause electromagnetic interference to other electronic devices. In the prior art, as shown in CN101494096A, the conductive fabric is bonded to the insulating material around the wire through a conductive pressure-sensitive adhesive. This structure is not only complicated to operate

Embodiment 1

[0023] In this embodiment, an electrolytic copper foil with a surface roughness of 0.2 μm and a thickness of 10 μm is used for the following surface treatment. The electrolytic copper foil is washed with alkali in an aqueous solution of sodium hydroxide with a concentration of 10 wt%, and then washed with water; Then, the activation treatment is carried out in dilute sulfuric acid with a concentration of 5wt%, and the activation treatment time is 10 minutes. After the pretreatment, the treated copper foil was oxidized in an oxidizing solution consisting of 0.05wt% 2-thiol imidazoline, 0.01wt% benzotriazole, 1.0wt% Tetraethoxysilane, 5.0wt% hydrogen peroxide, 5.0wt% sodium carbonate, and the rest water. The temperature of the oxidation treatment was 60° C., and the treatment time was 15 minutes.

Abstract

The invention relates to a flat cable used for a computer display, and belongs to the computer connecting line technology field. The flat cable used for the computer display comprises a plurality of conductors, which are arranged at certain intervals; and an insulation layer, which is disposed on the peripheries of the conductors in a covered manner. The plurality of conductors and the insulation layer are used to form a cable main body, and the conductors comprises two grounding conductors disposed on the end parts, and a plurality of signal transmission conductors disposed between the two grounding conductors. The outer part of the cable main body is provided with a copper foil layer, and an insulation covering layer used for covering the copper foil layer. The grounding conductors are electrically connected with the copper foil layer, and the oxidation treatment of the copper foil layer can be carried out. The flat cable used for the computer display is advantageous in that the flexibility is good, and the shielding performance can be improved, and the electromagnetic leakage can be effectively prevented, and therefore the requirements of the display on the miniaturization performance, the thinning performance, and the flexibility performance can be satisfied.

Description

technical field [0001] The invention relates to the technical field of computer connecting wires, and more specifically, the invention relates to a flat cable used for computer monitors and a preparation process thereof. Background technique [0002] Flat flexible cable, usually made of insulating material and extremely thin tinned flat copper wire, is a new type of data cable formed by pressing. It has the advantages of softness, flexibility, thin thickness, small size, simple connection, and convenient disassembly. The number and spacing of wires can be selected arbitrarily, which makes the connection more convenient, greatly reduces the volume of electronic products, reduces production costs, and improves production efficiency. It is most suitable for signal transmission cables between electronic equipment or circuit boards, especially for Applications where complex and / or spaces are tight and curved or flexed. [0003] As shown in CN101494096A, a plurality of wires arra...
