Hello everyone, I am a precision shield manufacturer hardware responsible for the production of Longhua shield processing. Today I bring you some knowledge about shielding covers. Let’s take a look! At present, the materials of the shielding cover on the market generally use stainless steel and cupronickel. The stainless steel has good shielding effect, high strength and moderate price, while the cupronickel shielding effect is slightly weaker, softer, and easy to deform. The price is generally about 30% more expensive than stainless steel. Although stainless steel is inferior to cupronickel in effect, it can solve the problem of tinning well after galvanizing. Generally, there are two shielding covers in mobile phones, covering the RF and BB sections 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. Choose, choose success
