Application and function of radio frequency shielding box
Radio frequency shielding box application, function and factors affecting the isolation of shielding box
The shielding box is a shielding body of various shapes such as shells, plates, sleeves made of conductive or magnetic conductive materials, which limits the electromagnetic ability to a certain space range and is used to suppress radiation interference. It also deals with conduction and radiation. To achieve a device that provides a non-interference test environment for the tested wireless communication device. There are two purposes of shielding:
One is to restrict the radiated electromagnetic energy inside the equipment from going out of a certain area;
The second is to prevent external radiated electromagnetic energy from entering a certain area.
The specific application situation of the shielding box For manufacturers of wireless communication products, the failure of the products to be put on the market in time or rapid mass production will bring about the reduction of output value and the loss of profits. Directly affect the follow-up business development and market share.
The radio frequency test process is usually the most complicated and influential process in the production line of wireless communication equipment such as mobile phones, and it is usually the bottleneck of the production line. The radio frequency test station is usually composed of test instruments, shielding boxes, test software, etc., and usually can be divided into calibration test, comprehensive test, antenna test, etc. Due to capacity requirements, the RF test process is usually run in parallel by multiple identical test stations.
The pass rate of one or some test stations is low; lower output will lead to bottlenecks in the production line and a sharp increase in production costs. The reasons can be roughly divided into: product design or material reasons, test problems (errors) Test problems), environmental factors such as radio frequency interference, and uncertain problems in the test.
Electromagnetic interference/EMI is a problem that must be faced and overcome in the entire electronic field. Generally, wireless communication products such as mobile phones, car anti-theft, wireless network cards, wireless routers, wireless headsets, Bluetooth headsets, wi-fi, wimax, data cards, In the process of board testing and final testing of wireless communication equipment such as walkie-talkies, RFID and other wireless communication modules, the test environment is improved by using the radio frequency test shield box/RF Shield Box.
Shielding box function
Isolate external base station signals
Isolate interference from adjacent test stations
Reduce the impact of personnel
Save Handling time
Integration of multiple testing processes to simplify the process
At present, the testing frequency of shielding boxes is mostly concentrated between 300mhz~7.5Ghz, and the number of ultra-low frequency and ultra-high frequency radio frequency products has also increased, which puts forward new requirements for the shielding effect and test processing methods of shielding boxes.
