Abstract:
A method for fabricating a substrate comprising a solder stop structure comprises providing a substrate configured to carry a surface mounted device, the substrate comprising a ceramic layer and a metallization arranged on the ceramic layer, wherein the metallization comprises a base metal layer and a noble metal layer covering the base metal layer, and generating an oxidation structure on the metallization, wherein the oxidation structure divides the metallization into a first part and a second part, and wherein the oxidation structure is configured to act as a solder stop, wherein generating the oxidation structure comprises partially removing the noble metal layer.
Abstract:
A method for connecting two connection partners includes: moving a second connection partner towards a first connection partner and simultaneously heating a first section of the second connection partner to soften the first section; and placing the second connection partner on the first connection partner such that the softened first section of the second connection partner directly contacts the first connection partner.
Abstract:
One aspect of the invention relates to producing a dried paste layer on a joining partner. For this purpose, a joining partner having a contact surface is provided, to which contact surface a paste is applied. Furthermore, a heating device is provided, which is preheated to a preheating temperature. The paste applied to the contact surface is then dried during a drying phase, such that a dried paste layer arises from the paste. In the drying phase, the joining partner and the preheated heating device are at a distance of at most 5 mm.
