ARTICLES AND METHODS INCLUDING PATTERNED SUBSTRATES FORMED FROM DENSIFIED, ADHERED METAL POWDERS
Abstract:
In general the disclosure relates to manufacturing methods for producing conductive patterns on flexible substrates. For example, a layer of a metal powder composition is deposited onto an adhesive overlaying a substrate. Pressure is applied to the metal powder composition on the adhesive coated substrate web by a die having one or more projections, in order to reproduce a pattern on the substrate. The metal powder is compressed by the projections of the die, thereby densifying the powder and causing it to adhere to the adhesive in a reproduction of the die pattern. The metal powder does not adhere substantially in uncompressed regions, and may be removed. In this manner, a metal powder composition may be densified and adhered to a substrate forming a web of flexible circuit elements, for example, circuit elements such as antennas, resistors, capacitors, inductive coils, conduction pads and the like.
