Guangdong metal shielding cover, let you know which areas need shielding cover + strict selection of raw materials imported and national standard original factory

Hello everyone, I am the hardware shield manufacturer hardware responsible for the production of metal shields in Guangdong. Today I will bring 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. Technology companies engaged in the production of mobile phone shields are mainly OEMs. Some private-owned companies with independent brands have introduced, digested, and absorbed foreign advanced technologies, and have accumulated technology and talents. The development path of enterprises participating in international market competition, the business model has begun to enter the brand era from the foundry era. Hardware, committed to being the best and most professional precision stamping processing factory in the world
