CAPACITOR MATERIAL USED IN CIRCUIT BOARD, CIRCUIT BOARD UTILIZING SAID CAPACITOR MATERIAL, METHOD OF MANUFACTURING CIRCUIT BOARD, AND INFORMATION PROCESSING SYSTEM UTILIZING CIRCUIT BOARD

摘要

PROBLEM TO BE SOLVED: To provide a new material which can be used as a part of a capacitor provided within a circuit board.

SOLUTION: A material used as a part of a capacitor provided within a circuit board includes a polymer resin (such as a cycloaliphatic epoxy resin or a phenoxy based resin) and a specified quantity of nanopowders made of a ferroelectric ceramic material (such as barium titanate). The nanopowders made of a ferroelectric ceramic material (such as barium titanate) have a particle size in the range of approximately 0.01 μm to approximately 0.90 μm, and selected particles among the particles have a surface area in the range of approximately 2.0 to approximately 20 square meters per gram. A capacitor using the material, a circuit board 27, an electrical assembly, and an information processing system (such as a personal computer) are also provided.
