Description

Technical Field

[0001] This utility model relates to a novel module FPC structure, and more particularly to a novel module FPC structure. Background Technology

[0002] Currently, the integration level of display modules used in mobile phones has increased. The charging lines, speaker signal lines, and other lines of the small board at the tail plug in the whole device are also connected to the main board of the mobile phone through the module FPC. Due to the increase in the charging power of mobile phones, these charging lines need to be set with a very wide line width in order to carry a large current. This will affect the bending performance of the module FPC during the subsequent assembly of the display module, resulting in problems such as excessive stiffness in the bending area, incomplete bending, and dead bending. This can lead to problems such as the screen not being able to light up or the module FPC damaging the screen.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a new type of module FPC structure.

[0005] The technical solution of this utility model is as follows: This utility model provides a novel module FPC structure, including: a module FPC body, on which charging lines are formed, and the charging lines have a plurality of hollow grooves formed at the bending areas corresponding to the module FPC body.

[0006] Furthermore, the width of the hollowed-out groove is 0.04mm-0.08mm.

[0007] Furthermore, the center distance between adjacent hollowed-out slots on the same charging line is 0.4mm-0.6mm.

[0008] Furthermore, the upper edges of all the hollowed-out grooves are not on the same straight line, and the lower edges of all the hollowed-out grooves are not on the same straight line.

[0009] Furthermore, in the bending area, the copper pouring of the module FPC body is a mesh copper pouring.

[0010] Furthermore, in the bending area, the cover film of the module FPC body has windows and a green oil layer is provided.

[0011] The beneficial effects of this utility model by adopting the above solution are as follows: by setting a hollow groove at the position of the charging line corresponding to the bending area of ​​the module FPC body, it can avoid the problems of the bending area being too stiff and difficult to bend due to the wide charging line at the bending area, thereby improving the quality of the product and avoiding problems such as the inability to light up the screen or damage to the screen in the future. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of the module FPC body according to an embodiment of the present invention.

[0013] Figure 2 This is a schematic diagram of the charging circuit according to an embodiment of the present invention. Detailed Implementation

[0014] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] Please refer to the following: Figure 1 and Figure 2 In this embodiment, the present invention provides a novel modular FPC structure, comprising: a modular FPC body 1, on which a charging line 11 is formed, and the charging line 11 has a plurality of hollow grooves 111 formed at the bending area A corresponding to the modular FPC body 1. The width of the hollow grooves 111 is 0.04mm-0.08mm. The center distance between adjacent hollow grooves 111 on the same charging line 11 is 0.4mm-0.6mm. The hollow layer provided at the bending area A of the charging line 11 can reduce the line width at the bending area A of the charging line 11 without adversely affecting the current carrying capacity.

[0016] Furthermore, the upper edges of all the hollowed-out grooves 111 are not on the same straight line, and the lower edges of all the hollowed-out grooves 111 are not on the same straight line. This avoids stress concentration caused by bending when the edges are on the same straight line, which could lead to problems such as wire tearing and improve product quality.

[0017] Furthermore, in the bending area A, the copper pour of the module FPC body 1 is a grid copper pour (not shown). Using a grid copper pour helps to reduce the problem of the bending area A being too stiff due to the excessively wide copper pour, and helps to improve the bending performance.

[0018] Furthermore, in bending zone A, the cover film of the module FPC body 1 has a window and a green oil layer is provided. By replacing the cover film with the green oil layer (not shown) in bending zone A, the problem of bending zone A being too stiff due to the cover film can be avoided, which helps to improve bending performance.

[0019] In summary, this solution, by setting hollow grooves at the corresponding bending areas of the charging lines on the module FPC body, can avoid problems such as excessive stiffness and difficulty in bending caused by the wide charging lines in the bending areas. This improves product quality and avoids subsequent issues such as the screen failing to light up or being damaged.

[0020] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
