Title:
SILVER-COATED SPHERICAL RESIN, METHOD FOR PRODUCING SAME, ANISOTROPICALLY CONDUCTIVE ADHESIVE CONTAINING SILVER-COATED SPHERICAL RESIN, ANISOTROPICALLY CONDUCTIVE FILM CONTAINING SILVER-COATED SPHERICAL RESIN, AND CONDUCTIVE SPACER CONTAINING SILVER-COATED SPHERICAL RESIN
Document Type and Number:
WIPO Patent Application WO/2012/023566
Kind Code:
A1
Abstract:
This silver-coated spherical resin comprises a spherical resin and silver that is applied over the surface of the spherical resin. The amount of silver is 2-80 parts by mass relative to 100 parts by mass of the silver-coated spherical resin, and the crystallite diameter of the silver as determined by an X-ray diffraction method is 18-24 nm. This method for producing a silver-coated spherical resin comprises a step wherein a spherical resin is pretreated with an aqueous solution of a tin compound and a subsequent step wherein the spherical resin is subjected to electroless silver plating using a reducing agent. In the above-mentioned pretreatment, the temperature of the aqueous solution of a tin compound is set at 20-45°C.
