THE PRODUCT METHOD OF HEATING FILM FOR ELECTROMAGNETIC SHIELDING

摘要

Disclosed is a manufacturing method of a heating film for shielding a magnetic wave. In the manufacturing method of the present invention, the heating film generates heat through power applied by a power unit and is manufactured by the following steps of: printing a pattern, and generating heat through power supplied from the power unit, on one surface of a substrate by using conductive ink; and printing a pattern, and generating heat through power supplied from the power unit, on the other surface of the substrate by using conductive ink. According to the present invention, the heating film effectively blocks a magnetic wave by applying a roll-to-roll printing method and a reverse-current print patterning technique thereto.
