摘要:
An ink-jet head and a method for manufacturing the ink-jet head are disclosed. The ink-jet head can include: a chamber, which may house a type of ink; a membrane, which may be formed on one side of the chamber, and in a surface of which a holding cavity may be formed; a lower electrode, formed on an inner surface of the holding cavity; and a piezoelectric component, held in the holding cavity. According to certain embodiments of the invention, the ink-jet head can be formed with thin-film type actuators, and the electrical properties of the ink-jet head can be improved.
摘要:
Disclosed is a method of manufacturing an inkjet head discharging ink. The method in accordance with an embodiment of the present invention can include: heating the inkjet head to a temperature over a melting point of a filler; filling the inkjet head with the filler such that a gap inside the inkjet head is filled with the filler; and discharging the filler out of the inkjet head such that the filler in the gap of the inkjet head remains.
