摘要：

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 be presented, as well as a mechanical and metallurgical analysis of the brazed connections. (C) 2012 Published by Elsevier B. V.
