COIL ELECTRICAL COMPONENT AND METHOD OF MANUFACTURING THE SAME
First Claim
1. A method of manufacturing a coil electrical component, the method comprising:
- (1) mixing magnetic material powder and adhesive powder in a predetermined proportion to form a solid mixture;
(2) disposing an object and the solid mixture in a mold having a predetermined shape, wherein the object is covered by the solid mixture, and the mold needs no high-pressure process; and
(3) heating the solid mixture in the mold such that the magnetic material powder are adhered by the adhesive powder and covers the object, so as to form the coil electrical component corresponding in shape to the mold.

Abstract
A coil electrical component and a method of manufacturing the same. Magnetic material powder and adhesive powder are mixed in a predetermined proportion to form a solid mixture. The solid mixture and an object, such as a coil or a core material surrounded by the coil, are filled in a mold having a predetermined shape. The solid mixture in the mold is heated such that the magnetic material powder is adhered by the adhesive powder and covers the object, so as to form the coil electrical component. The coil electrical component corresponds in shape to the mold. Therefore, the coil electrical component has stable quality, and can be manufactured with less time and lower cost.
