Aluminum foil tape and copper foil tape electromagnetic shielding effect?
Shielding effect is the same, because the aluminum is easier to oxidation than copper, easy welding and other reasons, the general shield with copper tape.
Enclose the receiving circuit, device, or system with a shield to prevent them from being affected by external electromagnetic fields.
Specifically, the use of shields will be components, circuits, assemblies, cables or the entire system of interference sources to prevent interference with the electromagnetic field outward diffusion;
The shielding in communication is the isolation of the metal between the two spatial regions to control the induction and radiation of the electric field, the magnetic field and the electromagnetic wave from one region to the other.
Electromagnetic shield refers to the use of conductive materials or ferromagnetic material made of components on the large-capacity turbine generator stator core end shield to reduce the end of the stator winding leakage in the structural parts caused by additional losses With local fever measures.
