Abstract:
The present invention relates to an electromagnetic shielding sheet capable of improving reliability. Particularly, the present invention provides a composite magnetic sheet for electromagnetic shielding structured such that an independent soft magnetic sheet, which has a low surface roughness, is laminated on the outermost surface of a soft magnetic sheet having a lamination structure, thereby implementing laminated composite sheets having different surface roughness or porosity characteristics; as a result, the reliability in an external hazardous environment, such as saline water, can be substantially enhanced while maintaining the efficiency of electromagnetic shielding.

Abstract:
Since the magnetic film of the present invention has a much thinner thickness compared to a corresponding conventional magnetic layer and radiator coil material assembly and has no adhesive layer or air layer between the magnetic layer and the radiator, permeability required at the time of charging can be improved, a loss rate can be reduced and high charging efficiency can be obtained, Furthermore, since a band width and a gain rate can be improved, the magnetic film can be very usefully applied to wireless charging products which pursue slimming in design.
