Abstract
A method of manufacturing a substrate of an ink ejecting device in which an electrode formed at the bottom surface of an air chamber is removed with a diamond disk, without erroneously removing an electrode formed at an actuator forming the internal surface of the air chamber, by forming the air chamber with a width not smaller than that of an ink channel. The diamond disk for removing the bottom surface of the electrode of the air chamber may be the same as or have the same dimensions (width) as the ink channel.
Claims24
A method of manufacturing a substrate of an ink ejecting device, the method comprising the steps of:
- preparing a substrate plate such that at least a part of the substrate plate is formed of piezoelectric ceramics;
- forming first grooves in the substrate plate that define ejecting channels that eject ink;
- forming at least one second groove on each side of each of the first grooves to define non-ejecting channels and actuator walls between the first grooves and the second grooves;
- forming a conductive layer over internal surfaces of the first grooves and the second grooves and over the actuator walls;
- and
- removing a portion of the conductive layer that is formed at a bottom surface of each of only the second grooves without removing any other portions of the conductive layer formed over the first grooves and the second grooves during the step of removing.
The method according to claim wherein the step of forming first grooves includes forming first grooves such that each of the first grooves has a width of 40 to 100 μm.
