Piezo-actuator manufacturing method for motor vehicle, involves applying screen print on side surface of piezo units to be contacted during application of conducting paste and removing screen print after hardening or annealing

摘要

The method involves implementing electrical contacting of inner electrodes by outer electrodes. The application of a conducting layer as the outer electrodes is carried out by a pattern printing method. A several of piezo-actuators is held in a scraper made of metal or plastic for implementation of the pattern printing method. A prefabricated screen print (10) is applied on a side surface of piezo units to be contacted, during application of a conducting QM21-Paste and is removed after hardening/annealing. A silver coated screen is impressed in a base metallic coating as the outer electrode.
