MAGNETIC DEVICE AND METHOD OF MANUFACTURING THE SAME

摘要

A magnetic device comprises a lead frame, a first core body and a coil. The lead frame has a first portion and a second portion spaced apart from the first portion. A first core body is disposed on the lead frame, wherein the first core body comprises a first through opening and a second through opening. A coil is disposed on the first core body, wherein the coil has a first terminal and a second terminal, wherein the first portion is electrically connected with the first terminal via the first through opening, and the second portion is electrically connected with the second terminal via the second through opening, respectively.

主权项

1. A method for forming a magnetic device, the method comprising the steps of:
forming a lead frame comprising a first bottom part and a first protrusion connected to the first bottom part; forming a first core body, wherein the first core body comprises a first through opening; placing the first core body on the first bottom part of the lead frame, with at least a part of the first protrusion of the lead frame disposed in the first through opening for electrically connecting with a first terminal of a coil on the first core body; and encapsulating the first protrusion of the lead frame and the coil by using a molding material.
