MAGNETIC PASSIVE COMPONENT AND METHOD FOR MANUFACTURING THE SAME

摘要

A magnetic passive component and a method for manufacturing the same are provided. The magnetic passive component comprises a magnetic core, a metal-wire-layer winding around the surface of the magnetic core, and an insulating layer provided between the magnetic core and the metal-wire-layer. The material of the insulating layer is a kind of insulating material containing additive of metal ions. To form the metal-wire layer, a trace of metal-wire layer should be made first in the surface of the insulating layer by laser activation and then adopt electroplating process to form the metal-wire layer so as to finally form a metal winding wire on a surface of the magnetic core. The magnetic passive component and the method for manufacturing the same disclose here can realize a simple process, a low manufacturing cost, an automatic manufacturing and a stable and reliable quality.
