Abstract

Abstract The invention relates to a method for the force-coupled and vacuum-tight bonding of components of ceramic material together or to metallic components by means of thermocompression while using a soldering material in the form of an AlMgZn alloy provided between the components to be bonded prior to the thermocompression process. The soldering material used consists preferably of an aluminum-zinc-magnesium alloy having 95% by weight of Al, 4% by weight of Zn and 1% by weight of Mg.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 74 words
A method for the force-coupled and vacuum-tight bonding of ceramic components together or to metallic components by means of thermocompression by using a soldering material provided between the components to be bonded prior to the thermocompression process, characterized by the use of a soldering material of an aluminum-zinc-magnesium alloy having the composition 91.1 to 97.7% by weight of Al, 1.6 to 5.3% by weight of Zn and 0.5 to 3.6% by weight of Mg.
