     Now Introduce  more information about electromagnetic shielding box: Many shielded equipment research and development businesses, in order to meet electromagnetic compatibility requirements for conductive coupling requires the use of filtering technology, filtering technology to assist in the use of the filter element; coupling the radiation need to be supplemented by the use of shielding technology.      Electromagnetic shielding box through the shell, boxes, panels made of a metal shield, will be limited to a method of electromagnetic waves within a certain area. Since the radiation is divided into near-zone field source, the magnetic field source and the far zone plane wave, and therefore shield shielding performance according to different radiation sources in material selection, structural shapes and apertures leakage control and other aspects are different.      In the current increasingly dense electromagnetic spectrum, a sharp increase in electromagnetic power density per unit volume, high and low level devices or equipment large number of mixed use and other factors lead to equipment and system electromagnetic environment deteriorating case, its importance becomes more prominent. In this chaotic electromagnetic interference environment, in order to better work of such high performance electromagnetic devices, electromagnetic shielding box on the essential.      Electromagnetic shielding box using conductive or magnetic material shells, plates, sets, and other various shapes shield the electromagnetic capacity constraints in a certain space range for suppressing interference metal body radiation, and conduction and radiation treatment to be measured in order to achieve wireless communication devices without interference device test environment.       Finally, Tojoin remind you that if you want the design to achieve the required shielding performance, you need to first determine the source of radiation, a clear frequency range, according to each band structure typical leak to determine the control element, and then select the appropriate shielding materials, design shield housing.
