Embodiment 1

[0030] Embodiment 1 of the present invention provides a veneer shielding structure, which is used to shield radiation sources in a veneer, such as figure 2 As shown, the shielding structure includes:

[0031] Shielding frame 102 and shielding film 101;

[0032] The shielding frame 102 is used to be fixedly arranged on the single board by welding, and the shielding frame is provided with partition ribs 103, and the partition ribs 103 divide the inside of the shielding frame 102 into multiple spaces, which can separate each radiation on the single board. source, the shielding film 101 is glued and tightly covered on the shielding frame 102, and the shielding film 101 is used as a shielding cover of the shielding frame 102, and cooperates with the shielding frame 102 to form a closed structure inside the shielding frame 102. That is, cooperate with the shielding frame 102 and the ribs 103 in the shielding frame 102 to form a plurality of closed structures in the shielding frame...

Embodiment 2

[0036] Embodiment 2 provides a veneer shielding structure, which is basically the same as the veneer shielding structure given in Embodiment 1. The difference is that the structure of the shielding film in the veneer shielding structure is as follows: Figure 4 As shown, it is a laminated structure formed by an insulating layer 21 , a wave absorbing layer 22 , a second insulating layer 23 and an adhesive layer 24 . Wherein, the wave-absorbing layer is made of wave-absorbing material, and the wave-absorbing material can be a material capable of absorbing electromagnetic waves, and its thickness can also reach 0.05-0.2mm. Other parts of the shielding structure of the veneer in this embodiment are basically the same as the shielding structure given in Embodiment 1, and reference may be made to the description of Embodiment 1, which will not be repeated here.

[0037] The shielding film used in the shielding structure of this embodiment also has the same characteristics as the shi...

Embodiment 3

[0039] Embodiment 3 provides a method for realizing a single-board shielding structure, such as Figure 5 As shown, the method includes:

[0040] Step A, setting the shielding frame on the veneer, setting partition ribs in the shielding frame, and separating each radiation source of the veneer through the partition ribs;

[0041]Step B, attaching a covering shielding film on the shielding frame after the ribs are provided, and cooperating the shielding film and the shielding frame to form a closed shielding structure in the shielding frame.

[0042] In step A of the above method, the shielding frame is arranged on the single board by welding and fixing the shielding frame on the single board, so that the shielding frame surrounds the radiation source to be shielded on the single board.

[0043] In step B of the above method, attaching and covering the shielding film on the shielding frame after the ribs are provided specifically includes: pasting and covering the shielding fi...

Abstract

The invention discloses a single board shielding structure, an implementation method thereof, a single board and communication equipment, and belongs to the technical field of communication. The single board shielding structure comprises a shielding frame and a shielding thin film, wherein the shielding frame is arranged on a single board; separating ribs used for separating each radiation sourceare arranged inside the shielding frame; the shielding thin film is covered on the shielding frame and cooperated with the shielding frame to form a closed structure inside the shielding frame. By covering the shielding thin film on the shielding frame as a shielding cover, the thickness of the single board can be effectively reduced when the shielding frame is increased so as to facilitate the light and thin design of product; besides, by taking the shielding thin film as a shielding cover of the shielding frame, the single board shielding structure is not only convenient to mount but also convenient to uncover to inspect and repair the devices inside the shielding frame; the shielding thin film uncovered also can be reused; moreover, due to the isolation of the shielding thin film, the risk of short circuit of the metallic shielding cover and the devices on the single board can be reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a single board shielding structure and its realization method, a single board and communication equipment. Background technique [0002] In communication terminal products such as mobile phones, PDAs, wireless data network cards, etc., the transmission rate is steadily increasing, and at the same time, it also brings a certain anti-interference vulnerability, because the higher the frequency of information transmission, the sensitivity of the signal increases, and their The energy is getting weaker and weaker, and the wiring system is more susceptible to interference at this time. The interference in the environment is ubiquitous, so the shielding of the board is becoming more and more important, and the shielding directly affects the manufacturability, assemblability and maintainability of the board. In the prior art, a shielding cover is generally installed on a single b...
