METHOD FOR MANUFACTURING ELECTRONIC COMPONENT WITH COIL
First Claim
1. An air-core coil comprising:
- a coil member that is formed by winding a flat rectangular wire, the coil member having first and second sides opposite to each other, the coil member having a coil axis; and
first and second leads that are formed by the flat rectangular wire and that are integrally connected to the coil member, the first and second leads respectively having;
first and second bent members at the first side;
first and second ends at the second side; and
first and second bottom extensions respectively connected between the first and second bent members and the first and second ends, whereinthe first and second bent members extend in a first direction parallel to the coil axis,the first and second ends extend in a second direction parallel to the coil axis, andthe first and second bottom extensions extend perpendicular to the coil axis.

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/cm2 to the mixture for adjusting an outer shape of the mixture by a movable punch of a press machine before the hardening process.
