Dongguan shielding cover, let you understand what is shielding cover +3.0 precision stamping design system [hardware]
Hello everyone, I am a hardware manufacturer of precision shielding covers that is responsible for the production of shielding covers in Dongguan. Today I will bring 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. Generally, there are two mobile phone shields in a mobile phone, covering the RF and BB sectors respectively. If it is a baseband circuit, a circuit board shield, like the core is an AMR9 high-speed circuit, or there are some inductive boost components in the baseband, shielding cover, mobile phone shielding cover on the one hand to prevent external electromagnetic radiation from affecting the radio frequency circuit, but also to prevent radio frequency interference Affect the normal operation of the devices in the baseband circuit, like a mobile phone shield. In detail, it is to use a shield to surround the interference source of components, circuits, assemblies, cables or the entire system to prevent the interference electromagnetic field from spreading out; use shielding The body wraps up the receiving circuit, equipment or system to prevent them from being affected by the external electromagnetic field. It can not only be said that the shielding cover is to prevent radiation or be radiated. 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 after-sales service responds to customers 24 hours a day.
