To enable high-volume production for the proposed nozzle-based droplet brazing process on sensitive substrates, reproducibility and robustness of the method will be increased significantly. To ensure joints with high strength and conductivity in serial production, control strategies will be developed to provide a basis for automation, and the nozzle geometry as well as the material are to be optimized. By local coating of polymer powder and simultaneous laser melting directly after the electrical joining, an insulation layer will be produced within an integrated process in order to shorten the process chain.

为了能够在敏感衬底上实现大批量生产，该方法的重复性和稳健性将大大提高。为了确保接头在连续生产中具有高强度和导电性，将制定控制策略，为自动化提供基础，并对喷嘴几何形状和材料进行优化。通过局部涂覆聚合物粉末，在电连接后直接进行激光熔化，在一个完整的工艺中产生一层绝缘层，以缩短工艺链。
