A flexible flat cable with a center distance of 0.3mm and its manufacturing method

Abstract

The invention discloses a flexible flat cable with a center distance of 0.3 mm and a manufacturing method thereof. The flexible flat cable includes a flexible flat cable body and a reinforcing plate in which a plurality of conductors are evenly arranged inside, and a gap between two adjacent conductors The distance between centers is 0.3mm, the width of the conductor is 0.15-0.20mm, and the thickness of the conductor is 0.025-0.050mm. The invention adopts hot-melt film bonding technology to produce flexible flat cables with a center distance of 0.3 mm. The entire production process does not involve the use of chemical substances, and will not endanger the environment and human health. Currently, there is no center distance lower than 0.3 mm in the market. Flexible flat cable, thus the technical solution provided by the present invention fills up the gap in the market and carries out technical innovation. The width of the conductor of the flexible flat cable provided by the present invention is 0.15-0.20mm, while the width of the conductor of the FPC in the prior art is only 0.1mm, so the current resistance of the present invention is much greater than that of the FPC in the prior art.

Description

technical field [0001] The invention relates to the field of cables, in particular to a flexible flat cable with a center distance of 0.3 mm. Background technique [0002] Flexible Flat Cable (FFC) is a new type of data cable made of PET insulation material and extremely thin tinned flat copper wire, which is pressed by high-tech automatic equipment production line. It has softness, random bending and folding, thickness Thin, small size, simple connection, easy disassembly, easy to solve electromagnetic shielding (EMI) and other advantages. [0003] In actual use, many mobile phone connections use such as figure 1 As shown in the cable, the cable includes a first conductor and a second conductor arranged alternately, the minimum width of the first conductor and the second conductor is 0.1mm, and the cable is made of FPC (flexible insulating substrate) with a center distance of 0.3mm printed circuit), the center distance is the center distance between two adjacent first con...

AI Technical Summary

Problems solved by technology

[0004] 1) The production cost is relatively high;

[0005] 2) FPC is formed through chemical corrosion processing, which is harmful to the environment;

[0006] 3) In order to avoid the design of the center distance of 0.3mm, the width of the conductor in some areas of the product is only 0.1mm, so the current resistance of the FPC is much weaker than that of the FFC with a conductor width of 0.15-0.20mm
