Abstract
For production of an electrically conductive or thermally conductive connection for contacting two elements, an elemental metal, in particular silver, is formed from a metal compound, in particular a silver compound, between the contact surfaces. In this production, the processing temperature for the use of a silver solder can be decreased below 240° C. and the processing pressure can be reduced to normal pressure. A contacting paste for this purpose contains a metal compound, in particular a silver compound, which decomposes below 400° C. while forming elemental silver. As a result, a metal is generated in situ from a chemical compound for producing a contact, which is usable above the temperature necessary for its production.
