Abstract
Ink jet printheads and printhead components are described. One printhead includes a flow path and a piezoelectric actuator. The flow path includes a pumping region and the piezoelectric actuator is associated with the pumping region. The actuator has a pre-fired piezoelectric layer with a thickness of about 50 microns or less. A bonding layer fixes the pre-fired piezoelectric layer relative to the flow path.
