Abstract
Electrically conducting adhesives having a broader selectable range of properties are provided by having random sizes of micrometer diameter range particles coated with a low melting temperature metal. The coated particles are suspended in a vehicle of a mixture of thermosetting resins together with a flux resin selected for viscosity and low shrinkage, for screen printability, for electrical and for mechanical properties over a broad range of specification conditions. The vehicle or resin system includes thermosetting cyclo-aliphatic epoxy, thermosetting phenoxy polymer and thermosetting mono-functional limonene oxide. The low temperature melting coating system for the particles includes In, Sn, and alloys such as In—Sn, Sn—Pb, Bi—Sn—In and InAg. The micrometer diameter range particles includes Cu, Ni, Co, Ag, Pd, Pt, polymer and ceramic.
