Electromagnetic shielding is mainly shielded electromagnetic waves. Some electronic components or equipment in the normal working state will generate electromagnetic waves, which will interfere with other electronic equipment; similarly, it will also be interfered by other equipment electromagnetic waves. Electromagnetic shielding body from the wire, cable, components, circuit or system and other external interference electromagnetic waves and internal electromagnetic waves are playing a role in absorbing energy (eddy current loss), reflecting energy (electromagnetic waves in the shield on the interface reflection) and offset energy (electromagnetic induction in the shield layer to produce reverse electromagnetic field, can offset part of the interference electromagnetic waves), so the shield has the function of reducing interference. The special copper foil for electromagnetic shielding produced by CIVEN METAL is the ideal shielding body material, which has the characteristics of high purity, good overall consistency, smooth surface, and easy to laminate.Copper Foil High-precision RA Copper Foil [HTE] High Elongation ED Copper Foil *Note: All the above products can be found in other categories of our website, and customers can choose according to the actual application requirements.
