Title:
CONDUCTIVE PARTICLES, METHOD FOR PRODUCING SAME AND ANISOTROPICALLY CONDUCTIVE ADHESIVE
Document Type and Number:
WIPO Patent Application WO/2011/158783
Kind Code:
A1
Abstract:
Disclosed are conductive particles which have a high rate of presence as primary particles (isolated particles) without being agglomerated, while suppressing as much as possible the ratio of such conductive particles wherein a part of the surface of a resin particle is not covered by an electroless plated metal thin film. The conductive particles are suitable for use in an anisotropically conductive adhesive. The conductive particles are configured of: resin particles the surfaces of which have been subjected to a melamine adsorption treatment for causing the resin particles to adsorb a melamine compound that is capable of self condensation by heat; and an electroless plated metal thin film which is formed on the surface of each resin particle. Preferably, the surface of the electroless plated metal thin film is provided with projections so as to reduce the connection resistance. The conductive particles are produced by a production method which comprises: a melamine adsorption step in which the surfaces of the resin particles are caused to adsorb a melamine compound; a catalyzation step in which a catalyst for accelerating the electroless plating is precipitated; and an electroless plating step in which a metal thin film is formed by electroless plating.
