Embodiment Construction

[0017] In order to have a deeper understanding of the technical means and effects adopted to achieve the creation of the present invention, it will be described in detail below in conjunction with the accompanying drawings, so as to thoroughly analyze the purpose, realization methods and special effects of the present invention. However, the following drawings are for reference only, and are not intended to limit the protection scope of the present invention.

[0018] Such as figure 1 Shown is a schematic flow chart of the main steps of the manufacturing method of the flexible cable of the present invention. The steps are as follows: first provide a flexible substrate, and set a metal conductor layer on it; then pattern the metal conductor layer to form a plurality of metal conductors arranged in parallel; then form an insulating layer on the flexible substrate On, the insulation layer covers the plurality of metal conductors 30 . In this embodiment, the flexible substrate i...

Abstract

The invention discloses a manufacturing method for a flexible flat cable. The manufacturing method comprises the following steps: providing a flexible base plate, and forming a metallic conductor layer on the flexible base plate; patterning the metallic conductor layer, and forming a plurality of metallic conductors which are uniformly arranged in parallel; and pressing an insulating layer onto the plural metallic conductors of the flexible base plate. After the manufacture of the plural metallic conductors in the flexible flat cable adopts the metallic patterning process, the flexible flat cable has the advantages that the space between conducting wires can be accurately controlled, and the dimensional tolerance of the size of the conducting wires can be reduced.

Description

technical field [0001] The invention relates to an electronic connection device, in particular to a manufacturing method in which the electronic connection device is a flexible cable. Background technique [0002] Flexible cable (FFC) is a transmission component made by arranging a plurality of metal conductors, covering the upper and lower sides with insulating material and hot pressing. It has excellent flexibility and is suitable for the connection between electronic systems in various small spaces. And transmit signals, and has the advantage of low production cost, so it has been widely used in various electronic products in recent years. Generally, the flexible cable has a three-layer structure, that is, from top to bottom: the arrangement of the insulating layer, the conductor layer, and the insulating layer. Each conductor is separated from each other and is partially exposed on both sides of the flexible cable. end to form a connection point. When the flexible cabl...
