Abstract
A hot-forming fabrication method of a magnetic component and a hot-formed magnetic component fabricated by the same are provided. More particularly, a magnetic powder hot-forming technique is provided, along with a hot-formed magnetic component fabricated by the hot-forming technique so as to have high inductance, low core loss, and high electromagnetic wave shielding efficiency. A low core low-core loss core for use in a common basic magnetic component is enclosed and thereby shielded by a single-layer or multi-layer EMI shielding material, thus producing an enhanced magnetic component with high inductance, low core loss, and low electromagnetic wave interference.
Claims14
A hot-forming fabrication method of a magnetic component, comprising steps of:
- winding a current-carrying coil around a core so as to form a magnetic energy storage component;
- placing the magnetic energy storage component in a mold, and disposing a magnetic shielding material around the magnetic energy storage component;
- and
- performing a hot-forming process so as to obtain a hot-formed magnetic component enclosed by the magnetic shielding material.
A hot-formed magnetic component, comprising:
- a core;
- a current-carrying coil wound around the core;
- and
- a magnetic shielding material enclosing the core and the current-carrying coil by a hot-forming process.
