Producing reactive semi-finished product for soldering process, comprises producing reactive layer arrangement, which contains reactive material system with two exothermic reaction partners reacted wi
The method comprises producing a reactive layer arrangement (2), which contains a reactive material system with two exothermic reaction partners reacted with one another, by galvanic deposition. The reactive layer arrangement is galvanically deposited on a workpiece (1) to be joined. The reactive layer arrangement is galvanically deposited as a component of a semi-finished film on a carrier substrate and then the semi-finished film is detached from the carrier substrate.The reactive layer arrangement is formed with a first reaction partner containing an alternating sequence of layers (2a).

The reactive layer arrangement is galvanically deposited on a workpiece (1) to be joined. The reactive layer arrangement is galvanically deposited as a component of a semi-finished film on a carrier substrate and then the semi-finished film is detached from the carrier substrate. The reactive layer arrangement is formed with a first reaction partner containing an alternating sequence of layers (2a) and with a second reaction partner containing layers (2b). The individual layers in the reactive layer arrangement are formed as nano-layers. The reactive layer arrangement is formed with a layer thickness of 20-150 mu m. The exothermic reaction partners are galvanically deposited by the electrolytes. The reactive layer arrangement is galvanically deposited under the use of a modulated current flow. During galvanic deposition of the reactive layer arrangement, a production process is selected from the groups of the production processes such as strip galvanizing process, dispersion deposition process and lithographic process. An independent claim is included for a reactive semi-finished product for a soldering process.
