With the continuous development of high technology, many high-tech products are constantly emerging. The shielding box has appeared in the development of technological products, and it has many shielding boxes with different functions.
1. The main function of the shielding box is to limit the electromagnetic capability to a certain space range to suppress radiated interference, and to process conduction and radiation to provide a non-interference test environment for the tested wireless communication equipment.
2. In terms of size, if you are measuring a mobile phone, generally the length, width, and height are more than 150X150X150 mm. A mobile phone with a 5-inch screen larger than the above size shouldn’t be a problem.
3. There are many brands of shielding boxes, and the price difference is also big. The key depends on how you judge whether it is genuine or not. The shielding boxes for testing mobile phones generally use cone-shaped shielding boxes.
4. Shielding boxes are generally made of aluminum and steel. Aluminum is relatively light, but has poor electromagnetic wave absorption capability. Stainless steel absorbs the best, but is relatively heavy. If you hear it lightly and have good absorbing capacity, it is usually fooling you. For the time being, this world can't take care of the shielding box that absorbs electromagnetic waves lightly and is good.
