Abstract
A method for manufacturing an electronic component for avoiding electromagnetic interference includes: (a) placing a T-shaped core and an air-core coil in a metal mold; (b) injecting a mixture of a composite magnetic material and a resin into the metal mold so that the T-shaped core and the air-core coil are embedded by the mixture; (c) heating the mixture at a first temperature; (d) adjusting an outer shape while removing excessive mixture; and (e) hardening the mixture. The method may further include a process of polishing an outside of the hardened mixture. The method may further include a process of applying a pressure of 0.1 to 20.0 kg/cmto the mixture for adjusting an outer shape of the mixture by a movable punch of a press machine before the hardening process.
