Title:
METHOD FOR MANUFACTURING NFC ANTENNA FOR PORTABLE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2015/122574
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing an NFC antenna for a portable terminal and, particularly, to a method for manufacturing an NFC antenna for a portable terminal, capable of directly forming the NFC antenna on the case of the portable terminal or the battery pack case of the portable terminal. The method for manufacturing an NFC antenna for a portable terminal, according to the present invention, comprises: a case preparation step for preparing the case of the portable terminal or the battery pack case for the portable terminal; a hydrophobic film formation step for forming a hydrophobic film on the entire surface of the case by dipping the case into a hydrophobic material aqueous solution; a laser irradiation step for irradiating an NFC antenna circuit pattern region of the case with a laser after the hydrophobic film formation step so as to remove the hydrophobic film on the surface of the circuit pattern region and at the same time, roughen the surface of the circuit pattern region; an NFC antenna circuit formation step for forming a circuit formation plating layer in the circuit pattern region by electroless plating after the laser irradiation step; and a ferrite sheet attachment step for attaching a ferrite sheet to the case so as to cover the circuit formation plating layer after the NFC antenna circuit formation step.
