CIRCUIT BOARD, CIRCUIT APPARATUS, AND METHOD OF MANUFACTURING THE CIRCUIT BOARD

摘要

A circuit board includes a substrate and an insulating layer. The substrate has a first surface. The insulating layer has a second surface and is connected to the substrate. The first surface is in contact with the second surface. Heat-conductive particles are provided in the insulating layer. A part of the particles projects from the second surface of the insulating layer and is in contact with the first surface of the substrate.
