  • Patent number: 8042726
    Abstract: To form high performance bonding connections suitable for producing micro-structured components made of a plurality of individual layers, bonding by the steps; providing at least two work pieces; forming a metal bonding layer on at least one side of at least one of said at least two work pieces by chemical or electrolytic metal plating method; the metal bonding layer being a nickel/phosphorous alloy having a prescribed phosphorous content and prescribed thickness; forming a bonding arrangement comprising said work pieces so that there is at least one metal bonding layer between said at least two respective work pieces; heating at a prescribed heating rate to a temperature above the melting temperature of the bonding layer; bonding the two work pieces by applying contact pressure within a prescribed range; and cooling at a prescribed rate.

  • Publication number: 20080217381
    Abstract: For forming very strong bond joints suited for manufacturing micro-structured components consisting of plurality of individual layers, a bonding method is proposed by which a bonding arrangement of the work pieces is formed that comprises at least one metallic bonding layer interposed therein between and by which the bonding arrangement is heated to a bonding temperature below the melting temperature of the at least one bonding layer. In accordance with the invention, the at least one bonding layer is deposited using a chemical or electrolytic method.
