Capacitor material for use in circuitized substrates, circuitized substrate utilizing same, method of making said circuitized substrate, and information handling system utilizing said circuitized substrate

摘要

A material for use as part of an internal capacitor within a circuitized substrate includes a polymer (e.g., a cycloaliphatic epoxy or phenoxy based) resin and a quantity of nano-powders of ferroelectric ceramic material (e.g., barium titanate) having a particle size substantially in the range of from about 0.01 microns to about 0.90 microns and a surface area for selected ones of said particles within the range of from about 2.0 to about 20 square meters per gram. A circuitized substrate adapted for using such a material and capacitor therein and a method of making such a substrate are also provided. An electrical assembly (substrate and at least one electrical component) and an information handling system (e.g., personal computer) are also provided.
