Mobile phone metal shielding cover, which shielding methods include +15 years, the shielding cover manufacturer tells you

The manufacturer hardware responsible for the processing of the metal shielding cover of mobile phones said that the process of designing the shielding layer of the high-frequency transformer includes three parts, namely the magnetic circuit, the magnetic circuit winding and the shielding cover. In order to avoid arcing, air gap and epoxy resin should be used. To increase the overall thickness of the shielding layer. Let’s take a look at the following: In the design process, a continuous shielding loop can be formed in the electrical characteristics by close to the winding of the high-frequency transformer, and a sufficient design distance between the winding and the winding can be maintained, which can be useful Avoid breakdown of the electrolyte inside the shielding layer to protect the normal operation of the high-voltage inverter. In order to ensure the shielding effect and shielding quality of the high-frequency transformer, the overall shielding ring size and design can be changed on the basic structure to ensure the heat dissipation effect of the shielding layer. Generally speaking, the interference generated around the electromagnetic field can be eliminated by magnetic shielding, magnetic isolation, transfer elements, etc. The transfer through magnetic materials can be more effective than other materials, so the high-frequency transformer shields In the process of layer design, magnetic materials with high permeability are usually used for production. The shielding effect should be analyzed according to the requirements of the shielding degree of the equipment or components. After shielding, the strength, attenuation rate and attenuation of the shielding magnetic field will also vary according to the thickness of the material's permeability and the size of the shield. Since high-permeability materials far exceed the price of low-permeability materials, when selecting shielding materials, in addition to analyzing the shielding effect of magnetic permeability materials, it is more important to judge based on economic costs. If the shielding effect of a single-layer high-permeability material is the same as that of a multilayer low-permeability material, a thin-thick, high-permeability material can be used to further reduce economic costs. Hardware, 15 years of focusing on mobile phone metal shielding cover, for the quality of the shielding cover, starting from the design of the mold, control every tiny movement and process, and the flatness is controlled within 0.07mm in the process. There are 16 quality inspections, and the quality is strictly checked. With a daily production capacity of 3 million strokes, every customer is satisfied with quality, service, and production capacity!
