Electromagnetic shielding, in simple terms, refers to the isolation of metal between two spatial regions to control the induction and radiation of electric fields, magnetic fields, and electromagnetic waves from one region to another. Specifically, it is to surround the interference sources of electronic components, circuits, assemblies, cables, or the entire system with shielding bodies to prevent the electromagnetic field from spreading outward; Alternatively, shielding can be used to enclose the receiving circuit, components, equipment, or system to prevent them from being affected by external electromagnetic fields.

The principle of electromagnetic shielding: When electromagnetic waves reach the surface of the shielding body, the impedance discontinuity at the interface between air and metal causes reflection of the incident wave. This reflection does not require a certain thickness of shielding material, as long as the discontinuity at the interface is considered; b、 The energy that enters the shielding body without being reflected off the surface is attenuated by the shielding material as it propagates forward within the body. That is to say, absorption; c、 When the remaining energy that has not been attenuated inside the shielding body is transmitted to another surface of the material and encounters a discontinuous interface between metal and air impedance, it will reflect again and return to the shielding body. This reflection may occur multiple times at the interface between two metals. In short, the attenuation of electromagnetic shielding is mainly based on the reflection and absorption of electromagnetic waves.

Electromagnetic Compatibility (EMC), abbreviated as EMC, refers to an electronic device that neither interferes with nor is affected by other devices. The interference of the magnetic field generated by electronic components on the outside world is called EMI (Electromagnetic Interference). The phenomenon of external electromagnetic waves interfering with electronic components is called EMS (Electromagnetic Susceptibility), such as the common "snowflake" on the fluorescent screen of old televisions, which indicates that the received signal is interfered with.

The raw materials we use are copper foil tape and excellent plastic insulation materials. Copper foil tape is divided into single-sided tape and double-sided tape. Single sided adhesive copper foil tape is divided intoSingle conductive copper foil tape and double conductive copper foil tapeSingle conductive copper foil tape refers to the adhesive surface that is non-conductive, with only the other side of copper conducting, hence it is called single conductive or single-sided conductive; Double conductive copper foil tape refers to the conductive surface covered with adhesive, which contains nickel, and the copper on the other side is also conductive, so it is called double conductive or double-sided conductive. There are also double-sided coated copper foil tapes used to process expensive composite materials with other materials. The adhesive surface of double-sided coated copper foil is also divided into conductive and non-conductive types Customers can choose according to their own needs for conductivity. Plastic insulation materials generally include PC, PET, PP, etc., with a temperature resistance of over 120 degrees Celsius and flame retardant levels of UL94-V2 and V0.
