Document Type and Number:
WIPO Patent Application WO/2024/014668
Kind Code:
A1
Abstract:
The present invention relates to conductive particles and, more specifically, to conductive particles applied to a connector for inspection that is disposed between terminals of a device to be inspected and a pad of an inspection device to perform an electrical inspection on the device to be inspected, a plurality of the conductive particles, disposed at each position corresponding to a terminal of the device to be inspected in an elastic insulating material, forming a conductive path due to the pressure from the device to be inspected. The conductive particles each comprises: a core particle including a ferromagnetic material; and a coating layer disposed on the surface of the core particle, wherein the coating layer is composed of a coating body surrounding the core particle, and a concave-convex portion formed on the outer surface of the coating body, the concave-convex portion being composed of a plurality of convex portions protruding from the outer surface of the coating body and concave portions provided between the convex portions, and formed by means of an etching process to protrude over the entire outer surface of the coating body.
