The importance of wireless shielding box

Author:admin   AddTime:2021-04-19

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 test problem of wireless products. The wireless test 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.

The methods and measures taken to prevent electromagnetic interference are called shielding. Its purpose is to limit the electromagnetic interference generated by electronic equipment or electronic components to a certain area or to protect electromagnetic sensitive equipment from external electromagnetic interference. The shielding box can provide a test environment without electromagnetic interference; isolate the influence between adjacent test equipment; it can effectively prevent the radiation of the tested product from affecting people.

At present, the wireless shielding box has become an indispensable equipment in the wireless communication industry. Various styles of shielding boxes can be seen in major enterprises. With the continuous upgrading of the wireless communication industry, the performance of the wireless shielding box will follow in its footsteps. More and more perfect. The wireless test shielding box is generally used in the board test and final test of mobile phones, wireless routers, wifi, bluetooth and other devices to provide a good environment for testing.



The shielded room we made is a measure to isolate electromagnetic field interference. Generally, a well-grounded metal mesh or cover is used to achieve electromagnetic shielding, which can not only prevent external electromagnetic field interference, but also prevent internal electromagnetic field radiation from interfering with the outside world. A high-permeability material cover is used to achieve magnetic shielding, which can prevent magnetic field interference. The electromagnetic shielding is one of the main measures of electromagnetic compatibility technology. That is, a measure to close the electromagnetic interference source with metal shielding material to make the external electromagnetic field strength lower than the allowable value; or to seal the electromagnetic sensitive circuit with metal shielding material to make the internal electromagnetic field strength lower than the allowable value Measures.

The physical concept of shielding refers to: shielding is the metal barrier between two spatial regions to control the induction and radiation of electric fields, magnetic fields, and electromagnetic waves from one region to another. In detail, the shielding body is used to surround the interference source of components, circuits, assemblies, cables or the entire system to prevent the interference electromagnetic field from dispersing outward.
