This paper presents latest results on the influences of nozzle material and geometry on the electromechanical contacting of sensitive piezoceramic actuator modules. Two nozzle types have been investigated,a standard WC/Co nozzle which is used for soldering applications and a novelceramic nozzle. Applications for active piezoceramic components integrated in structural parts are e.g. active damping,...
This paper describes a laser droplet brazing method for electrical contacting of sensitive piezoceramic actuator modules. In order to increase the reproducibility of the contacting process, the mass, the energy and the flight path of the braze droplets have to be controlled. For this reason, braze preforms are used which are molten by a single laser pulse. The system technology and first results will...
