How much do you know about the shielding box? As far as the editor knows, the shielding box is made of conductive masking cloth covered with a piece of silver-plated woven fabric on foam plastic to form a soft cushion, which takes up most of the loose space. Mainly for civilian use, suitable for foam cushion cabinets and door panels. The higher the magnetic permeability of the shielding box, the greater the thickness, and the smaller the magnetic resistance, the better the magnetic shielding effect will be. Of course, it must be coordinated with the weight of the equipment. The shielding of the high frequency magnetic field is realized by using the reverse magnetic field of the eddy current generated by the material with high conductivity to cancel the interference magnetic field.

The physical concept of the shielding box refers to: shielding is a metal barrier between two spatial areas to control the induction and radiation of electric fields, magnetic fields and electromagnetic waves from one area to another. In detail, the shielding body is used to surround the interference sources of components, circuits, assemblies, cables or the entire system to avoid the interference electromagnetic field from dispersing; the shielding body is used to surround the receiving circuit, equipment or system to prevent them from being affected. To the influence of the external electromagnetic field. Everyone has a relatively understanding of the concept of shielding boxes. Let's take a closer look at what are the functions of shielding boxes?



1. Isolating the interference of adjacent test stations is to restrict the radiated electromagnetic energy inside the equipment from going out of a certain area.

2. Save Handling time and reduce the impact of personnel. It can also prevent external radiated electromagnetic energy from entering a certain area.

3. Isolate external base station signals, integrate multiple test procedures, and simplify procedures.
