Abstract
A method for increasing the manufacturing certainty of soldered connections between a ceramic carrier and a printed-circuit board. It includes the method step of applying a first decomposition-resistant metallization layer on a ceramic carrier and the subsequent imprinting onto the first metallizing layer of a second metallizing layer, improving the wetting performance. In this manner, it is possible to achieve an increase in the overall metallizing layer thickness in the edge area of a soldered connection, whose solder rise in turn makes possible an optical, fully-automatic monitoring of the soldered connection.
