Conductive Compositions Containing Blended Alloy Fillers
US Patent:
8221518, Jul 17, 2012
Filed:
Mar 31, 2010
Appl. No.:
12/751030

Assignee:
Ormet Circuits, Inc. - San Diego CA
International Classification:
B22F 1/00, B23K 31/00
US Classification:
75252, 252513, 252514, 2282481, 228249
Abstract:
The present invention provides electrically and thermally conductive compositions for forming interconnections between electronic elements. Invention compositions comprise three or more metal or metal alloy particle types and an organic vehicle comprising a flux that is application specific. The first particle type includes a reactive high melting point metal that reacts with a reactive low melting point metal(s) in the other particles to form intermetallic species. The reactive low melting point metal(s) of the invention are provided in two distinct particle forms. The first reactive low melting point metal particle includes a carrier that facilitates the reaction with the reactive high melting point metal. The second reactive low melting point metal particle acts primarily as a source of the reactive low melting point metal. Combination of the three particle types provides several advantages including reduction of the undesirable characteristics of the carrier metal while preserving and, in some embodiments, enhancing, the advantageous facilitation of the metallic reaction.

International Classification:
B05D 5/12, B05D 5/00, B05D 3/02, B22F 1/00, B22F 1/02, C08K 3/08
US Classification:
427123, 75255, 75228, 524439, 524440
Abstract:
The present invention provides conductive metal compositions for electronic applications, and methods of preparation and uses thereof. More specifically, the present invention provides metallic particle transient liquid phase sintering compositions containing blended formulations of metal and metal alloy components that form interconnected conductive metallurgical networks with increased stability, resistance to thermal stress and ability to mitigate CTE mismatch between materials.

International Classification:
B23K 35/02, B23K 1/20
US Classification:
2282481, 75255, 75252, 75338
Abstract:
Transient liquid phase sintering compositions comprising one or more high melting point metals and one or more low melting temperature alloys are known in the art as useful compositions for creating electrically and/or thermally conductive pathways in electronic applications. The present invention provides transient liquid phase sintering compositions that employ non-eutectic low melting temperature alloys for improved sintering and metal matrix properties.
