Abstract
This paper deals with investigations for production of thermally and mechanically stable joints on thin metal coated active elements achieved by the use of three laser-based micro joining technologies: Laser Droplet Welding (LDW), laser soldering and laser brazing. First, the different laser processes and experimental setups are described. A double-beam LDW process head allows the deposition of molten metal droplets on the electrodes of the active elements. The deposited droplets are welding the joining partners. The limited energy of the droplets shall prevent the ceramics and its metallization from being damaged. For laser brazing and soldering a temperature control will be regarded which aims to reduce an overheating of the process area. In the second main part of this paper the quality of the realized joints will be described in terms of micrographs.
