Abstract
The invention relates to a method for forming a bonded joint between a structure that is applied to a glass substrate, in particular a printed conductive structure and an electrical connecting component, in particular a solder base by using solder coated or non-solder coated reactive nanometer multilayer foils which are made from at least two exothermally reacting materials. Initially preconfiguring the reactive nanometer multilayer foils according to the opposing joining surfaces of the conductive structure and the electrical closure element is performed. Thereafter arranging a solder preform respectively between the respective joining surface and the nanometer multilayer foil for non-solder coated foils or arranging an additional solder preform for already solder coated nanometer multilayer foils is performed, wherein the solder preform or the additional solder preform includes a larger, in particular double thickness layer compared to another solder preform between the nanometer multilayer foil and the a conductive structure applied to the glass substrate so that a reduction of the temperature introduction into the conductive structure and a leveling of uneven portions is caused. After temporarily applying a pressure force which is applied between the joining surfaces triggering the exothermal reaction of the nanometer multilayer foil is performed by an electrical impulse or a laser impulse.
