Abstract:
A method for producing a surface on a component, which has regions having different wettabilities with respect to a solder. The method includes forming a first metallic layer on the component and forming a second metallic layer on the first metallic layer, the second metallic layer preventing oxidation of the first metallic layer. The method furthermore includes removing the second metallic layer with the aid of a laser in a predefined surface region for exposing the first metallic layer, and oxidizing the exposed first metallic layer on the surface, which results in a wettability with respect to a solder in the predefined surface region that is less than in a surface region adjacent to the predefined surface region.
