Process for selective soldering

摘要

Process for the selective formation of contact metallisations on terminal areas of a substrate, wherein the surface of the substrate is covered with a template in such a way that template openings forming deposit spaces are arranged above the terminal areas, and wherein the deposit spaces are filled with a solder material, and fusing of the solder material is effected with a view to forming the contact metallisations in the deposit spaces which are non-wettable at least in regions of contact with the solder material.
