US Classification:

148527, 148536, 148537, 427 79, 427101

Abstract:

A passive electrical article comprising (a) a first self-supporting substrate having two opposing major surfaces, (b) a second self-supporting substrate having two opposing major surfaces, and (c) an electrically insulating or electrically conducting layer comprising a polymer and having a thickness ranging from about 0. 5 to about 10 m between the first and second substrate, wherein a major surface of the first substrate in contact with the layer and a major surface of the second substrate in contact with the layer have an average surface roughness ranging from about 10 to about 300 nm and wherein a force required to separate the first and second substrates of the passive electrical article at a 90 degree peel angle is greater than about 3 pounds/inch (about 0. 5 kN/m), a printed wiring board or a flexible circuit comprising the passive electrical article, an electrical device comprising the printed wiring board or the flexible circuit comprising the passive electrical article, and a method of manufacturing the passive electrical article.

Filed:

Jun 21, 2005

Appl. No.:

11/157531

Inventors:

Joel Peiffer - Maplewood MN, US
Nelson O'Bryan - Woodbury MN, US

International Classification:

H01L 21/00
H01L 33/00

US Classification:

438027000, 257098000

Abstract:

A passive electrical article includes a first electrically conductive substrate having a major surface and a second electrically conductive substrate having a major surface. The major surface of the second substrate faces the major surface of the first substrate. An electrically resistive layer is on at least one of the major surface of the first substrate and the major surface of the second substrate. An electrically insulative layer is between the first and second substrates and in contact with the electrically resistive layer. The insulative layer is a polymer having a thickness ranging from about 1 μm to about 20 μm. The insulative layer has a substantially constant thickness.
