Title:
ANISOTROPIC CONDUCTIVE ADHESIVE, PROCESS FOR PRODUCING SAME, CONNECTION STRUCTURE, AND PROCESS FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2012/005144
Kind Code:
A1
Abstract:
Disclosed is an anisotropic conductive adhesive in which the conductive particles thereof exist in an insulating adhesive composition without aggregating in cases where magnetic powder particles, such as nickel-coated resin particles, are used as the conductive particles of the anisotropic conductive adhesive. In the anisotropic conductive adhesive, magnetic powder particles in which at least a portion thereof is made of a magnetic material are used as the conductive particles. The conductive particles are demagnetized either in a state where the conductive particles are still powder particles before being dispersed in the insulating adhesive composition, in a state where the conductive particles have been dispersed in the insulating adhesive composition and made into a paste, or in a state where the paste has been made into a film, before anisotropic conductive connection is performed by using the anisotropic conductive adhesive.
