Abstract
Description
Technical Field
[0001] This application relates to the field of shielding paper technology, and more specifically, to an alignment protection paper. Background Technology
[0002] Shielding paper is a functional material used for electromagnetic shielding. It primarily protects electronic devices, communication components, and sensitive circuits by suppressing electromagnetic interference (EMI) and electromagnetic radiation (EMR). Its core principle is to utilize the reflection and absorption properties of conductive or magnetic materials to confine electromagnetic waves to a specific area. It is widely used in smartphones, laptops, automotive electronics, aerospace, and other fields.
[0003] Currently, many module projects require modification of the shielding paper after the finished product is manufactured, resulting in the lack of alignment lines and difficulty in application. This necessitates mold modification and the re-fabrication of alignment lines on the backlight frame. This is costly, especially for small-scale projects, making it very uneconomical.
[0004] Based on this, this application designs an alignment protectant paper. Utility Model Content
[0005] The technical problem to be solved by this utility model is that the shielding paper is modified after the module project is completed, resulting in the shielding paper not having alignment lines and being difficult to apply.
[0006] To solve the above-mentioned technical problems, this utility model provides an alignment protective paper, which adopts the following technical solution: The shielding paper includes symmetrical cross-shaped cuts at both ends of the FPC. The cross-shaped cuts are hollow and the width of the gap is 0.15-0.2mm. A transparent PET film is attached to the outside of the cross-shaped cuts of the shielding paper.
[0007] Furthermore, the shielding paper is a film containing conductive material, used to protect the component area and prevent external signal interference.
[0008] Furthermore, the size of the transparent PET II should cover the entire cross-shaped cut.
[0009] Furthermore, a transparent PET layer is provided in the middle of the shielding paper near the component area.
[0010] Furthermore, the size of the transparent PET film should cover the entire component area to isolate the component area from the shielding paper and prevent short circuits.
[0011] Furthermore, the cross-shaped cut should not be placed in the area where the shielding paper is located in the component area to avoid electrostatic damage to the components.
[0012] Furthermore, the upper end of the shielding paper is provided with a rectangular notch to avoid the FPC connection end.
[0013] Compared with the prior art, the present invention has the following main advantages: This invention features symmetrically cut cross-shaped slits at both ends of the shielding paper, with a slit width of 0.15-0.2mm. A transparent PET film is attached to the outside of the cross-shaped slits. During use, the two cross-shaped slits allow for precise positioning and adhesion of the entire shielding paper, preventing misalignment or crooked application. Attached Figure Description
[0014] To more clearly illustrate the solution of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

Figure 2 This is a schematic diagram of the structure of a positioning protectant paper proposed in this application; Figure 3 This is a side view of an alignment protectant paper proposed in this application; Figure 4 This is a schematic diagram illustrating the bonding of a positioning protective paper according to this application; Figure label: Shielding paper 100, 200; Transparent PET-101, 201; Cross-shaped incision 202; Transparent PET 203; Rectangular notch 204; FPC 300; Component area 400; Backlight positioning line 500. Detailed Implementation
[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.
[0017] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0018] Reference Figure 1 The existing protective paper includes shielding paper 100. A transparent PET-101 is provided in the middle of the shielding paper 100 near the component area 400. The size of the transparent PET-101 is to cover the entire component area 400 to isolate the component area 400 and the shielding paper 100 to avoid short circuits. When pasting the shielding paper 100, in order to avoid the shielding paper 100 being pasted off-center or crooked, backlight positioning lines 500 need to be made at both ends of the backlight iron frame. When pasting, align the two ends of the shielding paper 100 with the backlight positioning lines 500 to paste the shielding paper 100 correctly.
[0019] However, many module projects currently require modification of the shielding paper 100 after the finished product is manufactured. Due to the change in the size of the shielding paper 100, the backlight alignment line 500 is missing, making it difficult to apply. This necessitates mold modification and the re-fabrication of the alignment lines on the backlight frame. This increases costs, which is particularly uneconomical for small-scale projects. Therefore, improvements to the existing protective paper are needed.
[0020] Based on this, embodiments of this application provide an alignment protectant paper, referring to... Figures 2-4 The shielding paper 200 has symmetrical cross-shaped cuts 202 at both ends of the FPC 300 (flexible printed circuit board). The cross-shaped cuts 202 are hollow and the gap width of the cross-shaped cuts 202 is 0.15-0.2mm. A transparent PET 203 is attached to the outside of the cross-shaped cuts 202 of the shielding paper 200.
[0021] This invention features symmetrically arranged perforated cross-shaped cuts 202 at both ends of the shielding paper 200. The width of the cuts 202 is 0.15-0.2mm. A transparent PET film 203 is attached to the outside of the cross-shaped cuts 202 of the shielding paper 200. In use, the entire shielding paper 200 can be positioned and attached through the two cross-shaped cuts 202, which can prevent misalignment and crookedness.
[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

A transparent PET 203 is attached to the outside of the cross-shaped cuts 202 of the shielding paper 200, and the size of the transparent PET 203 should cover the entire cross-shaped cut 202. A rectangular notch is provided at the upper end of the shielding paper 200 to avoid obstructing the connection end of the FPC 300.
