Description

Technical Field

[0001] The utility model relates to the technical field of FPC manufacturing, in particular to an FPC panel. Background Art

[0002] FPC is a printed circuit board made of a flexible insulating substrate, which has many advantages that rigid printed circuit boards do not have. Usually a display screen module will have multiple FPCs such as backlight FPC, LCD panel FPC and touch FPC, and each FPC corresponds to a panel supply. Due to the different shapes of FPCs, the board cannot be fully utilized. The shape utilization rate of some FPCs is low, which will cause great waste. China's patent application number CN201510978455.5 discloses an FPC panel and its panel design method. The FPC panel includes a substrate, and the substrate is provided with a plurality of large panels, and the large panels are arranged in a matrix. The large panels are also provided with blank areas, and the blank areas are provided with a plurality of small panels. The FPC panel adopts a design of mixed distribution of large and small panels, and the large panels are distributed in a matrix, which can greatly improve the utilization rate of materials. However, the L-shaped large board can achieve matrix distribution to cover the entire substrate. For a T-shaped large board, a simple matrix distribution will cause a waste of substrates. At the same time, small boards are laid in the blank area of ​​the large board. After the large board is removed from the substrate, the overall structure of the substrate becomes very soft, making it inconvenient to remove the small board. In addition, the small board is located in the blank area of ​​the large board and has an irregular structure, making it inconvenient to directly remove the small board first. Therefore, the utility model discloses an FPC panel to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0024] As described in the background technology, the existing FPC panelization adopts a design of mixed distribution of large and small boards, and the large boards are distributed in a matrix, which can greatly improve the utilization rate of materials. However, the large board is L-shaped and can achieve a matrix distribution to cover the substrate. For the T-shaped large board, a simple matrix distribution will cause a waste of substrates. At the same time, small boards are laid in the blank area of ​​the large board. After the large board is removed from the substrate, the overall structure of the substrate will become very soft, which is not convenient for removing the small board. In addition, the small board is located in the blank area of ​​the large board, and the structure is irregular, which is not convenient for directly removing the small board first.

[0025] In order to solve this technical problem, the utility model provides an FPC panel, which is applied to the field of FPC manufacturing.

[0026] Specifically, please refer to Figures 1-3 The FPC panel specifically includes a substrate 1, on which a plurality of first board units 2 are arranged, the first board units 2 are of a T-shaped structure, the first board units 2 are grouped in two and the two first board units 2 in each group are rotationally symmetrical, the first board units 2 are arranged in a matrix on the substrate 1 in groups, a blank area 3 is provided in each group of first board units 2, a reinforcement structure 4 is provided in the blank area 3, and a second board unit 5 is provided on the inner side of the reinforcement structure 4.

[0027] The FPC panel provided by the utility model rotates and symmetrically forms a group of I-shaped first board units 2 of a T-shaped structure, and then arranges each group of first board units 2 in a matrix to maximize the utilization of the substrate 1, and sets the second board unit 5 in the blank area 3 formed by each group of first board units 2, so that large and small board units are mixed and distributed on the substrate 1, thereby improving the utilization rate of the material of the substrate 1, avoiding the waste of the substrate 1, reducing product costs, and improving market competitiveness. At the same time, a reinforcement structure 4 is set to improve the strength of the substrate 1, avoid flexible deformation of the substrate 1, facilitate the removal of the first board unit 2 and the second board unit 5, and improve the processing efficiency.

[0028] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0029] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0031] Please refer to Figures 1-3, a flexible printed circuit (FPC) panel is provided, which includes a substrate 1. The substrate 1 is rectangular. A number of first board units 2 are arranged on the substrate 1. The first board units 2 are in a T-shaped structure. Taking two first board units 2 as a group, and the two first board units 2 in each group are rotationally symmetric. The first board units 2 are arranged in a matrix along the length direction of the substrate 1 in groups. Four groups of first board units 2 are arranged in each row. A blank area 3 is provided inside each group of first board units 2. A reinforcement structure 4 is provided inside the blank area 3. The reinforcement structure 4 is fixedly connected to the substrate 1. A second board unit 5 is arranged inside the reinforcement structure 4. There are two second board units 5 and they are rotationally symmetric. The second board unit 5 is in an L shape.

[0032] To facilitate the removal of the first board unit 2, a first punching line 6 is arranged along the periphery of the first board unit 2 between the first board unit 2 and the substrate 1. And a number of first connection points 7 are connected between the first board unit 2 and the substrate 1. The first punching line 6 is punched on the substrate 1 by punching, and the first board unit 2 is connected to the substrate 1 by using the first connection points 7 to prevent the first board unit 2 from falling. When the first board unit 2 is taken later, it can be directly torn off from the first connection points 7.

[0033] Two first board units 2 in each group form a "worker" shape, and the vertical boards of the two first board units 2 in each group are staggered. Adjacent groups of first board units 2 are staggered up and down, and the adjacent two groups of first board units 2 enclose the blank area 3, which can maximize the utilization of the substrate 1, and the distance between two adjacent first board units 2 is 2.2 - 2.6 mm.

[0034] The FPC panel provided in Embodiment 1 is further optimized. Specifically, as Figure 1 shown, first positioning holes 8 and first optical fiducials 9 are arranged on the substrate 1. There are five first positioning holes 8. Four of them are distributed at the four corners of the substrate 1, and the fifth first positioning hole 8 is arranged at one end of the substrate 1 and avoids the middle position, so that the five first positioning holes 8 are asymmetric. Thus, the substrate 1 is positioned by using the first positioning holes 8, and the asymmetric setting can also play an anti-fooling role to avoid misplacing the substrate 1 during silk screening or printing.

[0035] The FPC panel provided in Embodiment 2 is further optimized. Specifically, as Figure 1 、 3As shown, the reinforcement structure 4 is a closed-loop copper wire, which is fixedly connected to the substrate 1, thereby increasing the strength of the substrate 1. A second punching line 10 is provided inside the reinforcement structure 4, and a number of second connection points 11 are provided on the second punching line 10. A unit board body 12 is formed within the second punching line 10. The second board unit 5 is disposed on the unit board body 12. The second board unit 5 can be processed together with the first board unit 2. After the punching of the second punching line 10 is completed, the unit board body 12 is taken out from the substrate 1, and then the second board unit 5 is taken out from the unit board body 12. Moreover, a third punching line 13 is provided along the periphery of the second board unit 5 between the second board unit 5 and the unit board body 12, and a number of third connection points 14 are provided on the third punching line 13. The second board unit 5 is torn along the third connection points 14 on the third punching line 13, thereby removing the second board unit 5, which is convenient for operation.

[0036] A plurality of second positioning holes 15 and second optical punctuation marks 16 are provided on the unit board body 12. The second positioning holes 15 are asymmetrically arranged to play an anti-fooling role. After the unit board body 12 is taken out from the substrate 1, when the second board unit 5 has different shapes or the mold has been made into a whole, after replacing the second board unit 5, the unit board body 12 can be taken out from the substrate 1, so that the second board unit 5 on the unit board body 12 can be processed separately, realizing the diversity of the second board unit 5.

[0037] The working principle of the FPC panel provided by the present utility model: According to the design drawing, the arrangement and distribution of the first board unit 2 and the second board unit 5 are drawn on the substrate 1, and then the copper wire is fixed on the substrate 1, so that the second board unit 5 is located inside the copper wire. After the processing of the first board unit 2 and the second board unit 5 on the substrate 1 is completed, the substrate 1 is punched by using punching equipment, so that a first punching line 6, a second punching line 10 and a third punching line 13 are formed on the substrate 1. First, the first board unit 2 is torn along the first punching line 6, and then the unit board body 12 is torn from the substrate 1 along the second punching line 10. It can be selected to reprocess the second board unit 5 on the unit board body 12. Finally, the second board unit 5 is torn from the unit board body 12 along the third punching line 13, completing the processing of the first board unit 2 and the second board unit 5, achieving the maximum utilization of the substrate 1, and arranging the second board unit 5 in the blank area 3 formed by each group of the first board units 2, realizing the mixed distribution of the large and small board units on the substrate 1, improving the utilization rate of the substrate 1 material, avoiding waste of the substrate 1, reducing the product cost, enhancing the market competitiveness. At the same time, the reinforcement structure 4 is provided to increase the strength of the substrate 1, avoid flexible deformation of the substrate 1, facilitate the removal of the first board unit 2 and the second board unit 5, and improve the processing efficiency.
