Abstract
A composition of matter having a metal powder or powders of specified characteristics in a Reactive Organic Medium (TOM). These compositions can be applied by any convenient printing process to produce patterns of electrical conductors on temperature-sensitive electronic substrates. The patterns can be thermally cured in seconds to form pure metal conductors at a temperature low enough to avoid damaging the substrate.
Claims15
A compositionl of matter comprising a reactive organic medium and a metal powder mixture, wherein said composition can be applied on a substrate and heated in an oven to consolidate the composition to a solid pure metal conductor at a temperature below about 450° C.
A method for producing solid pure metal conductors on a substrate comprising the steps of:
- A) applying a conductor precursor in a pattern on to the substrate;
- B) heating said substrate with said patterned precursor in an oven to a critical temperature less than about 450° C. for a time less than about five minutes;
- wherein said applied conductor precursor pattern is converted into a consolidated, bonded pure metal conductor
- wherein said conductor precursor is comprised of a reactive organic medium and a metal powder mixture.
