Wireless shielding box

Author:admin   AddTime:2021-03-11

By the end of 2012, the number of connected devices (supporting any one or combination of Wi-Fi, Bluetooth, and GPS) on the earth will exceed the number of people. By 2020, the number of connected devices is expected to reach 50 billion, and the average person on the planet will have six connected devices, of which the number of devices that support Wi-Fi will exceed half. On the other hand, the surge of data traffic on the mobile Internet, especially the rapid promotion of video applications, will become the main source of mobile data traffic in the future.

At present, there are dozens of shielding boxes used for wifi testing, and under the development trend of 5G wifi in the future, shielding boxes will follow in their footsteps. In addition to standardizing the assembly process and improving shielding performance, the most important thing is filtering technology. To improve, the most effective filtering method at present is nine-level filtering, which can reduce electromagnetic interference to a minimum or even completely disappear. The prospect of shielding boxes is very worthy of attention.

Wireless shielding boxes have become indispensable equipment in the wireless communication industry. Various styles of shielding boxes can be seen in major companies. With the continuous upgrading of the wireless communication industry, the performance of wireless shielding boxes will follow in their footsteps. The more perfect. The wireless shielding box is generally used in the board test and final test of devices such as mobile phones, wireless routers, wifi and bluetooth, to provide a good environment for testing.



The shielding box conduction is a key part of the processing. When testing, putting the product in the shielding box must communicate with the outside of the shielding box through an interface, and a test instrument must be connected. If the interface filtering is not good, the radio frequency line connected to the instrument will become an antenna to guide the signal into the shielding box, then there will be no shielding effect, and the isolation will be extremely reduced. The shielding box can only ensure a good shielding effect by ensuring good electrical continuity, and the upper and lower cover contact faces of the shielding box put forward new requirements at this point. If the other places are done well, but the contact surface is not handled properly, then the shielding The isolation of the box will also be greatly reduced. Most of the contact surfaces of the shielding box are treated with shielding strips, copper mesh or beryllium copper shrapnel.

As science and technology enter a high-speed track, wireless technology is changing with each passing day, and wireless products cover all corners of the world. Then comes the problem of wireless product testing. The wireless shielding box in the production test is the main way to solve electromagnetic interference. Nowadays, communication companies are paying more and more attention to issues related to product quality. In order to prevent poor test quality due to electromagnetic interference during testing, the demand for wireless shielding boxes has increased, and the use of wireless shielding boxes in product production testing has also increased. The proportion.
