ABSTRACT:
A piezoelectric ceramic ink-jet print head is made by an inventive ultrasonic bonding process. Specifically, there are several improved features of ink jet print heads, including a more cost-effective bonding process using an ultrasonic bonding technique, an improved piezoelectric ceramic crystal pattern, and improved print head-piezoelectric electrical contacts. Further, there is an ultrasonic bonding process joining metallic objects with ultrasonic energy.
