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.

A method for reversibly attaching a phase changing metal to an object, the method comprising the steps of: providing a substrate having at least one surface at which the phase changing metal is attached, heating the phase changing metal above a phase changing temperature at which the phase changing metal changes its phase from solid to liquid, bringing the phase changing metal, when the phase changing metal is in the liquid phase or before the phase changing metal is brought into the liquid phase, into contact with the object, permitting the phase changing metal to cool below the phase changing temperature, whereby the phase changing metal becomes solid and the object and the phase changing metal become attached to each other, reheating the phase changing metal above the phase changing temperature to liquefy the phase changing metal, and
removing the substrate from the object, with the phase changing metal separating from the object and remaining with the substrate.
