Title:
INSULATED COATED CONDUCTIVE PARTICLES, ANISOTROPIC CONDUCTIVE ADHESIVE AND CONNECTED STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2017/138483
Kind Code:
A1
Abstract:
Provided are insulated coated conductive particles which enable the achievement of a good balance between excellent insulation reliability and conduction reliability even in a connection between micro circuits. Each insulated coated conductive particle 100a comprises a conductive particle 1 and a plurality of insulating particles 210 that are adhered to the surface of the conductive particle 1. The average particle diameter of the conductive particles 1 is from 1 μm to 10 μm (inclusive). The insulating particles 210 include first insulating particles 210a having an average particle diameter of from 200 nm to 500 nm (inclusive) and second insulating particles 210b formed from silica and having an average particle diameter of from 30 nm to 130 nm (inclusive).
