摘要： An inkjet head manufacturing method is disclosed. The method of manufacturing an inkjet bead including a plurality of chambers, configured to contain ink; and an actuator, configured to provide pressure to the chamber, which includes forming a piezoelectric element on one side of the inkjet head that is adjacent to the chambers; forming the actuator(s) by dicing the piezoelectric element such that the piezoelectric element is divided and placed corresponding to a position of the chamber(s); and etching one side of the inkjet head such that a part of the piezoelectric element remaining between the adjacent actuators, can manufacture an inkjet head having a thin-film actuator reducing the cross talk by removing a part of the piezoelectric element remaining between the actuators of the inkjet head.

摘要： An ink-jet head is disclosed. The ink-jet head can include a chamber for holding ink, an actuator that can provide pressure to the chamber, and a nozzle that includes a multiple number of channels for ejecting the ink. Certain embodiments of the invention can reduce the surface tension of the ink droplets and thereby reduce the capacity requirement of the actuators.
