Dongguan metal shielding cover, take you to understand the knowledge of shielding cover +3.0 precision stamping design system [hardware]

Hello, everyone, I am National Model Technology, a metal shield manufacturer responsible for the production of metal shields in Dongguan. Today, National Model Technology brings you some knowledge about shielding covers. Let’s take a look! The mobile phone shield is a metal shell mounted on the electronic motherboard. The interference source of the components, circuits, assemblies, cables or the entire system is surrounded by its own shield to prevent the interference electromagnetic field from spreading out and pass the board. The upper device is isolated to achieve the effect of shielding various electromagnetic devices, so that it can minimize crosstalk and sensitivity without affecting the operating speed of the system. Shielding cover is also called magnetic shielding. It is generally made of magnetically permeable materials. The best is permalloy, but it is expensive. Generally, magnetically conductive silicon steel tape or iron is used to make it. Then where are the shielding covers mainly used? What role does it play? Choose, choose success
