Dongguan shielding cover, let you understand what a shielding cover is + more than 20 mold R u0026 D design engineers [hardware]

Hello everyone, I am a hardware shield manufacturer that is responsible for the production of shielding covers in Dongguan. Today, Hardware brings you some knowledge about shielding covers. Let’s take a look! 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 price of the shielding cover varies greatly due to the price of raw materials, and the materials used are different, but the materials are only the following: stainless steel, nickel silver, tin bronze, brass, tinplate, etc., of which nickel silver, stainless steel, and tinplate are the most used. widely.
