Problems solved by technology

[0003] The traditional PCB board is a hard board, because of its own characteristics that the hard board cannot be bent, so it will inevitably occupy a certain amount of space and increase the weight of the product. Small direction development strategy
In addition, from a technical point of view, the mobile phone touch screen adopts the process of pressing AG wires to achieve connection. If the hard board is too thick, it will not be flat after pressing, and the steps will be large, and the AG wires will break.
In addition, the demand of the market continues to be refined, and the general double-sided flexible printed circuit board will also be restricted due to its thickness, and it is impossible to selectively design more compact and reliable products.
Ordinary hollow flexible circuit board, because the product is too delicate after division, it is not easy to work in the process of gluing and pressing the screen, and the gluing is uneven, resulting in bad situations such as steps and detachment after pressing the AG. At the same time, in the later product use process There will be potential safety hazards, and in the film-to-film pressing process, there will be poor products, low production efficiency, and high scrap rates

specific Embodiment approach

[0020] figure 1 It is a schematic diagram of the side mechanism of an embodiment of the present invention.

[0021] Such as figure 1 As shown, a hollow double-sided flexible printed circuit board printed with ACP conductive glue includes a substrate 2, a surface covering film 1, a bottom covering film 3, a copper strip 4 and a copper strip covering film 5, wherein the surface covering film 1 and The bottom cover film 3 is respectively pressed on the surface of the substrate 2 and the ground, the surface cover film 1 is provided with solder joint openings (not shown in the figure), and the bottom cover film 3 is provided with a guide hole 6 to realize conduction on both sides. The strip 4 is pressed on the bottom cover film 3 at the position where wiring is required, and pure glue is pasted between it and the bottom cover film 3. The bottom cover film 3 and the copper strip 4 have a circuit pattern on the surface, and a layer of wire is pressed on the surface of the line. The...

Abstract

The invention discloses a hollow-out double-sided flexible printed circuit board with ACP conductive adhesive being printed thereon, which comprises a base plate and covering films. The base plate adopts pure copper foil; a surface covering film with welding point openings and a bottom surface covering film provided with guide holes are respectively pressed on the surface and the bottom surface ofthe base plate; copper rods are pressed on the surface of the bottom surface covering film where wire layout is required; patterns for forming circuits are arranged on the surfaces of the copper rodsand the bottom surface covering film; a copper rod covering film with only welding point openings being exposed is pressed on the surfaces of the circuits; purity gum is adhered between the copper rods and the bottom surface covering film; and the ACP conductive adhesive is printed in the positions of the welding points. The hollow-out double-sided flexible printed circuit board has the advantages of light weight, miniaturization and slimming, simultaneously the design is convenient to be operated, the thickness of the position of the welding point is thinner, the thinnest position is 0.07 mm, integral printing is adopted during the process of online production of the product so as to facilitate the operation, the gumming is uniform, the production efficiency is improved, the safety quality potential is eliminated, and the environmental requirement is satisfied due to the printed ACP conductive adhesive.

Description

technical field [0001] The invention relates to a flexible circuit board, in particular to a hollow double-sided flexible printed circuit board printed with ACP conductive glue suitable for a touch screen of a mobile phone. Background technique [0002] As we all know, with the development of science and technology, applied electronic products are gradually developing in the direction of lightness and multi-function, especially with the development of communication technology, mobile phones have become an indispensable part of people's daily life, and people's personalization of mobile phones Requirements continued to increase, and mobile phones with touch screens followed. [0003] The traditional PCB board is a hard board, because of its own characteristics that the hard board cannot be bent, so it will inevitably occupy a certain space and increase the weight of the product. The above two disadvantages have restricted the product from becoming thinner and more refined Sm...
