Electrical shielding cover, how much do you know about shielding cover + 15 years of shielding cover manufacturer to show you

The hardware that produces electrical shields has said that shielding is the isolation of metal between two spatial areas to control the induction and radiation of electric fields, magnetic fields and electromagnetic waves from one area to another. Specifically, shielding is used to surround the interference source of components, circuits, assemblies, cables or the entire system to prevent the interference electromagnetic field from spreading; shielding to surround the receiving circuit, equipment or system to prevent them from being exposed to the outside world. The influence of electromagnetic fields. The following Xiaoshuo will take you to understand: Because the shielding body absorbs energy (eddy current loss) and reflects energy (electromagnetic waves on the shielding body). The interface reflection) and cancellation of energy (electromagnetic induction produces a reverse electromagnetic field on the shielding layer, which can cancel some of the interference electromagnetic waves), so the shield has the function of reducing interference. (1) When the frequency of the interfering electromagnetic field is high, the eddy current generated in the low-resistivity metal material is used to form the cancellation effect of the external electromagnetic wave, so as to achieve the shielding effect. (2) When the frequency of interfering electromagnetic waves is low, materials with high magnetic permeability should be used, so that the lines of magnetic force are limited to the inside of the shield and prevent spreading to the shielded space. (3) In some cases, if a good shielding effect is required for both high-frequency and low-frequency electromagnetic fields, different metal materials are often used to form a multi-layer shielding body. Hardware, focusing on electrical shielding covers for 15 years, focusing on the quality of shielding covers, starting from the design of the mold, and doing every tiny movement and process well, 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!
