Dongguan mobile phone shield, has cooperated many times with global top 500 companies + 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 for mobile phones in Dongguan. Today I will bring you some knowledge about shielding covers. Let’s take a look! Dongguan mobile phone shielding cover is a metal shell mounted on the electronic motherboard. The interference source of components, circuits, assemblies, cables or the entire system is surrounded by its own shielding body to prevent the interference electromagnetic field from spreading out and passing the The device isolation on the board achieves the effect of shielding various electromagnetic devices, so that crosstalk and sensitivity are minimized 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 mobile phone 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 the after-sales service responds to customers 24 hours a day.
