METHOD OF MANUFACTURING SOFT MAGNETIC POWDER AND INDUCTOR USING THE SAME

摘要

Disclosed herein is a method for manufacturing a shape-controlled soft magnetic powder which comprises adding a surfactant to a soft magnetic powder, and ball milling the mixture, wherein the shape-controlled soft magnetic powder has a thickness-to-diameter ratio of from 3 to 100. Further disclosed is a method for fabricating a wound-type inductor using the shape-controlled soft magnetic powder, comprising the steps of: coating a binder onto a shape-controlled soft magnetic powder; shaping the soft magnetic powder coated with the binder at room temperature; heat treating the shaped soft magnetic powder; and winding the heat-treated soft magnetic powder with a copper wire. Further disclosed is a method for fabricating a chip-type inductor using the shape-controlled soft magnetic powder.
