Abstract:
1. A method for highly precise, freely positionable fixing of a miniaturized component, in particular comprising a microoptical element, to a predetermined fixing section of a baseplate by means of a solder joint, the baseplate having a top and a bottom and the component having a base surface, at least the fixing section of the baseplate being coated on the top with at least one metal layer, and solder material being applied at least to the fixing section of the baseplate, which section is coated with the metal layer, the method comprising the steps of: arranging and holding the component above the fixing section of the baseplate in a starting position with a vertical distance between the base surface and the metal layer, the solder material on the metal layer being present in the intermediate space between the metal layer and the base surface, and the solder material and the base surface of the component being present opposite one another without contact, a vertical distance apart so as to form a solder-free intermediate space between the solder material and the base surface, while the component is held in the starting position above the fixing section with the vertical distance between the base surface and the metal layer, supplying heat energy in a region locally limited to the fixing section for at least partial melting of the solder material from the bottom of the baseplate so that, as a result of drop formation of the molten solder material, the solder-free intermediate space is filled with the molten solder material for mutual fixing, and waiting for the mutual fixing, the metal layer being applied to the top of the baseplate at least in the fixing section in a continuously planar manner and thus being without interruptions in the fixing section.
