Huizhou shield manufacturer, 3.0 level precision stamping design system + 30000+ sets of stamping die custom production experience [hardware]

Hello everyone, I am a precision shield manufacturer hardware responsible for the production of Huizhou shield manufacturers. Today I will bring you some knowledge about shielding covers. Let’s take a look! Shield Design Specification Preface Shielding is the isolation of metal between two space 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 sources 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 external electromagnetic fields Impact. Shielding covers are widely used in electronic products. There are sensitive circuits in electronic products, and these sensitive circuits are susceptible to other external influences. The current of the external circuit will generate an electric field around it, and then generate a magnetic field to form electromagnetic radiation. The larger the current value, the stronger the generated magnetic field, and the stronger the influence of the external circuit on the sensitive circuit, causing the sensitive circuit to have the problem of chaotic data transmission and inaccurate data. In addition, high-speed signal lines will also have an impact on sensitive circuits. The transmission rate of high-speed signal lines is very fast. High-speed pulses will reflect and crosstalk the signals of sensitive circuits. The hardware and system are complete and formal, the team is stable, and there is a stepped reserve of technical personnel, which can respond in time when the order breaks out, and the after-sales service responds to customers 24 hours a day.
