Method of manufacturing magnetic shielding block for wireless power chargers
Embodiments provide a magnetic shield for wireless power chargers and a method of manufacturing the same. The method includes forming flake powder having flake-type particles, forming an oxide film by performing oxygen heat treatment on the surface of the flake powder, performing insulation treatment on the surface of the flake powder provided with the oxide film formed thereon, and producing a sendust block by mixing and melting the insulation-treated flake powder and insulative resin powder. Therefore, a magnetic shield having high insulation characteristics and magnetic permeability may be provided.
