Passive electrical article, circuit articles thereof, and circuit articles comprising a passive electrical article

A method of manufacturing a passive electrical article comprising the steps of:

• (1) providing a first metal substrate, having two opposing major surfaces, substantially free of debris or chemisorbed or adsorbed materials and a second metal substrate, having two opposing major surfaces, substantially free of debris or chemisorbed or adsorbed materials,
• (2) providing a dielectric or conductive blend comprising a resin,
• (3) coating the blend onto a first major surface of the first metal substrate so that the blend, after curing or drying, forms a layer having a thickness ranging from about 0.5 to about 10 μm,
• (4) forming a laminate by contacting the first major surface of the second metal substrate or a first major surface of the second metal substrate coated with the blend with the coated first major surface of the first metal substrate using an applied pressure of from 5 to 300 psi, and
• (5) curing or drying the blend,
• wherein the first and second metal substrates are annealed before step (2) or as a consequence of (5),
• wherein the first major surface of the first metal substrate and the first major surface of the second metal substrate have an average surface roughness ranging from about 10 to about 300 nm, and
• wherein a force required to separate the first and second metal substrates of the passive electrical article at a 90 degree peel angle is greater than about 3 pounds/inch (about 0.5 kN/m).
