Abstract
A passive electrical article including a dielectric layer having a nonwoven material.
Claims14
A method of making an electrical article comprising:
- providing two conductive substrates,
- coating a resin on a surface of each conductive substrate,
- providing an etched nonwoven material between the resin-coated surfaces of the conductive substrates, the etched nonwoven material having a desired areal density, and
- laminating the resin-coated conductive substrates and the etched nonwoven material together,
- wherein the providing an etched nonwoven material step comprises providing a first nonwoven material having a first areal density larger than the desired areal density and etching the first nonwoven material to produce the etched nonwoven material, the desired areal density being 20 percent to about 50 percent lower than the first areal density.

A method of making an electrical article comprising:
- coating a resin layer on a surface of a first conductive substrate,
- forming an etched nonwoven material on a surface of a second conductive substrate, the etched nonwoven material having a desired areal density, and
- laminating the conductive substrates together with the resin layer and the etched nonwoven material facing each other,
- wherein the forming an etched nonwoven material step comprises providing a first nonwoven material having a first areal density larger than the desired areal density and etching the first nonwoven material to produce the etched nonwoven material, the desired areal density being 20 percent to about 50 percent lower than the first areal density.

A method of making an electrical article comprising:
- forming an etched nonwoven material on a first surface of one or both of a first and second conductive substrate, the etched nonwoven material having a desired areal density;
- coating a resin layer on the first surfaces of both conductive substrates, and
- laminating the conductive substrates together with the resin-coated first surfaces facing each other,
- wherein the forming an etched nonwoven material step comprises providing a first nonwoven material having a first areal density larger than the desired areal density and etching the first nonwoven material to produce the etched nonwoven material, the desired areal density being 20 percent to about 50 percent lower than the first areal density.
