Dendritic powder materials for high conductivity paste applications

Abstract

Pastes of dendrite particles coated with an electrically conductive coating are described. A surface is placed in contact with an electrolytic or electroless plating solution. Dendrites are formed on the surface. The dendrites are exposed to another plating solution to plate a coating on the surface of the dendrites. The coated dendrites are removed from the surface to form a powder of coated dendrites. The powder is added to a polymer material to form a paste. The paste is disposed between electrical contacts on adjacent surfaces. The paste is heated to fuse the dendrite surfaces to form a network of fused dendrites which are also fused to the electrical contacts. The paste is further heated to cure the polymer to form electrical interconnections between the electrical contacts on the adjacent surfaces.
