Title:
METHOD FOR MANUFACTURING MAGNETIC HEATING ELEMENT PARTICLES, CONDUCTIVE PASTE, AND METHOD FOR FORMING CONDUCTIVE FILM USING SAME
Document Type and Number:
WIPO Patent Application WO/2021/241769
Kind Code:
A1
Abstract:
The present invention provides a method for manufacturing a conductive film, comprising the steps of: applying, to a substrate, a conductive paste dispersed in an organic material and comprising metal particles and Fe-B-Cu-C alloy magnetic heating element particles; and selectively sintering the applied conductive paste by means of induction heating so as to form a conductive film, wherein the magnetic heating element particles are implemented with crystallized Fe-B-Cu-C alloy particles. Therefore, it is possible to selectively form a conductive adhesive layer by sintering through induction heating. In addition, it is possible to produce an adhesive capable of low-temperature bonding by forming a magnetic heating element having crystal grains with a large coercive force through heat treatment after formation of an alloy.
