Abstract

A fixture with a shaped molding may hold a first micro-actuator part and a second micro-actuator part in place for coupling while maintaining the structure of the first micro-actuator part. The first micro-actuator part and the second micro-actuator part may be a frame or a strip of piezoelectric material. A vacuum nozzle system embedded in the fixture may hold the first micro-actuator part in place. A mobile vacuum nozzle system may hold the second micro-actuator in place and positions the second micro-actuator part relative to the first micro-actuator part. A camera system may monitor the process. A dispense may apply epoxy between the first and second micro-actuator part. An ultraviolet source may provide ultraviolet radiation for curing.
