Title:
METHOD FOR MANUFACTURING ELECTRONIC CARD COMPRISING COIL PATTERN CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2020/153514
Kind Code:
A1
Abstract:
A method for manufacturing an electronic card, according to the present invention, comprises the steps of: forming a plurality of first guide grooves on a first sheet; forming a coil pattern circuit on the first sheet so that the electrical connection location of the coil pattern circuit is in the plurality of first guide grooves while a portion of the coil pattern circuit crosses the first guide grooves; forming a second guide groove on a second sheet having a size corresponding to that of the first sheet so that the second guide groove has a region that continuously includes the plurality of first guide grooves; stacking the second sheet on the first sheet so as to form a coil inlay in which the first guide groove is exposed through the second guide groove; forming a circuit module insertion groove in a region which corresponds to an external region of a circuit module at a location at which the electrical connection location of the coil pattern circuit is aligned with an electrical connection location of the circuit module, and which excludes the region of the second guide groove; and loading the circuit module on the circuit module insertion groove and connecting the coil pattern circuit to the circuit module at the upper part of the first guide grooves.
