The shielding principle of the mobile phone shielding box is through the shielding material, shielding copper mesh, tinned steel plate, and tin foil sealing of the box. The signal shielding effect of the mobile phone can be achieved without powering on. So which type of mobile phone shielding box is more appropriate?
1.The testable range of shielding box is generally from 300M-6GHZ
2. Isolation of shielding box is divided by materials, some of them are relatively strong, and some are poor.
3. There are two types of shielding box materials: aluminum and steel. Aluminum is relatively light, but its ability to absorb electromagnetic waves is poor. Stainless steel absorbs it best, but it is bulky. If you hear it lightly and have good absorptive power, it is usually flickering. The world cannot yet take into account shielding boxes that absorb electromagnetic waves lightly and are good.
4. In terms of size, if you are measuring a mobile phone, the general length, width, and height are 150X150X150mm or more. A 5-inch screen phone should be larger than the size above. If you want to reserve for expansion, use a bigger one.
5. There are many shielding box brands, and the price difference is also large. The key is how you judge whether it is real. The shielding box for mobile phones is generally a conical shielding box.
Which specification of the mobile phone shielding box is more suitable? The content mainly shares the above. In the era of the developed Internet, the network is developing very fast. The security problem behind the development of information technology has become a severe test at the moment. Monitoring is a problem that needs to be addressed in some places. Therefore, Jiachen believes that it is necessary to build a mobile phone shielding box.
