- an external extraction electrode extends from an ink chamber electrode formed in the ink chamber to the outside of the ink chamber.
- the external extraction electrode and the external circuit are connected.
- the ink chamber electrode and the external circuit are electrically connected.
- a dry film resist is laminated on one main surface of a piezoelectric element polarized in the thickness direction.
- the piezoelectric element is half-diced using the dicing blade of the dicer.
- an ink chamber 250 is formed in the half-diced portion.
- an R portion 251 at the rear end of the ink chamber is formed.
- the half die is repeated a plurality of times so that the plurality of ink chambers 250 extend in parallel with each other. In this manner, an ink chamber array 400 in which a plurality of ink chambers 250 are provided is formed.
- a metal which becomes an electrode material such as A1 or Cu is oblique to the main surface of the ink chamber array 400 in a direction perpendicular to the direction in which the plurality of ink chambers 250 extend. It is deposited obliquely. This operation is performed in two oblique directions with respect to the direction in which the ink chamber 250 extends.
- an ink chamber electrode composed of the metal film 350 is formed on the surface of the ink chamber partition wall 300.
- the shadow 1 ⁇ in g effect of ink chamber partition 3 0 0 of the ink chamber 2 5 0 Doraifi Rumurejisuto and each is exhibited.
- the metal film 350 on the inner surface of the ink chamber 250 Force Formed at a height of about 1/2 or less of the height of the inner wall surface of the ink chamber 250.
- the metal film 350 is formed also on the curved surface portion (R portion) 251 at the rear end of the ink chamber 250 and the dry film resist opening at the flat portion 260. Thereafter, only the dry film resist provided on the flat portion 310 on the upper surface of the ink chamber partition wall 300 separating the plurality of ink chambers 250 is removed. Thereby, the metal films 350 facing each other in the ink chamber 250 can be electrically connected in the R portion 251.
- a cover 210 having an ink supply hole 209 is adhered to the ink chamber array 400. Further, a nozzle plate 211 having nozzles 212 is adhered to the ink chamber array 400. As a result, the actuator 200 is completed.
- This actuator 200 has opposite phases to two ink chamber electrodes made of a metal film 350 formed so as to face both inner side surfaces of the ink chamber partition wall 300 separating the ink chamber 250.
- the ink chamber partition wall 300 is bent in a “U” shape or a mountain shape.
- the volume in the ink chamber 250 changes. Therefore, the pressure of the ink in the ink chamber 250 changes.
- ink droplets are ejected from the minute nozzles 21 arranged at the tip of the ink chamber 250.
- the active area 252 contributing to ink ejection is located only on the front end side of the ink supply hole 209.
- the area behind the ink supply holes 209 is an area that does not contribute to ejecting ink.
- the metal film 350 formed on the R portion 25 1 and the flat portion 260 electrically connects the two ink chamber electrodes facing each other in the ink chamber 250. As a result, the electrode conductive to the driving IC 115 and the metal film 350 are electrically connected.
- the above-described inkjet head needs to extend the metal film 350 from the inside of the ink chamber 250 to the flat portion 260 using a piezoelectric substrate such as PZT (lead zirconate titanate) having a high dielectric constant. There is. Therefore, the capacitance caused by the piezoelectric substrate increases. As a result, when the actuator is driven, the driving voltage applied to the actuator is disturbed. Therefore, in the conventional inkjet head, since the frequency of the driving voltage becomes small, it is difficult to perform high-speed printing by high-speed driving.
- the disturbance of the waveform of the applied drive voltage can be improved by increasing the voltage applied to the actuator.
- the applied voltage by increasing the applied voltage, the amount of heat generated by driving the actuator increases, so that the temperature of the actuator itself increases.
- conventional ink-jet heads have problems such as the fact that ink viscosity changes and printing cannot be performed stably and with high accuracy, the cost of driving ICs to which a high voltage is applied increases, and power consumption is reduced. The problem is that it is difficult to do so.
- an ink jet head in which a region other than the active area 25 2 is not provided on an extension of the ink chamber of the piezoelectric substrate is provided. It is disclosed in Japanese Unexamined Patent Publication No. 9-94954.
- the ink supply is provided with an ink supply hole 110 at the rear end of the active layer of the piezoelectric substrate.
- the electrode 111 in the ink chamber is extended to the outer surface on the ink supply side or the inner surface on the ink discharge side. Thereby, The electrode 111 in the ink chamber is electrically connected to the electrode 112 that is electrically connected to the driving IC 115. In this case, since the portion other than the active area of the actuator is not provided on the piezoelectric substrate, the material cost of the piezoelectric substrate can be reduced.
- the electrode 111 in the ink chamber is extended to the outer surface on the ink supply side or the inner surface on the ink ejection side, the capacitance of the extended portion due to the piezoelectric substrate of the electrode 111 in the ink chamber is increased. The problem that reduction cannot be achieved remains.
- the electrodes 111 in the ink chamber are drawn out by bending 90 ° at the corners of the piezoelectric substrate constituting the actuator.
- the extraction electrode is electrically connected to the indoor electrode.
- a dicing or YAG (Yttrium Aluminum Garnet) laser-separating step of the electrodes is required after extracting the electrodes to a resist pattern or a solid electrode in advance. Therefore, the process is very complicated, the productivity is poor, the production yield is reduced, and the production cost is increased.
- the extracted electrode is a bent portion that is drawn out from the ink chamber to the side of the actuator, and is likely to be disconnected in a later process or during the transportation of the actuator, thereby reducing the production yield and environmental reliability. Is also inferior.
- the extraction electrode can be formed by a plating technique.
- the plating technique requires a patterning step or an electrode separation step like the vapor deposition technique. Therefore, there is a problem that the process becomes complicated.
- the extraction electrode shown in FIG. 16 described above is highly likely to be broken at a bent portion drawn out of the ink chamber to the side of the actuator due to a handling mistake in a later step. For this reason, the conventional ink jet head has a problem that production yield is reduced and a problem that environmental reliability is inferior. Disclosure of the invention
- An object of the present invention is to reduce power consumption, to achieve high productivity and reliability, and to perform high-speed printing. It is to provide a possible ink jet head and a method for its manufacture.
- the ink jet head of the present invention includes an ink chamber provided on the surface of the piezoelectric substrate so as to extend from one end to the other end, and a driving electrode provided inside the ink chamber.
- the inkjet head includes an external connection electrode connected to the driving electrode and connected to an external electrode provided outside. Further, in the ink jet head, the electrode for external connection is formed of a conductive material filled in the ink chamber at one end of the ink chamber.
- portions other than the active area of the piezoelectric substrate constituting the actuator become almost unnecessary. Therefore, the material cost of the piezoelectric substrate can be reduced.
- the ink jet head it is not necessary to draw out the external connection electrode from the inside of the ink chamber along the surface of the piezoelectric substrate outside the ink chamber. For this reason, an increase in the capacitance due to the extraction portion of the external connection electrode is suppressed. Thereby, the driving frequency can be improved. As a result, high-speed printing becomes possible.
- the withstand voltage of the driving IC can be reduced. Therefore, according to the above-described inkjet head, it is possible to reduce the cost of the driving IC and the driving power consumption of the driving IC. .
- the conductive material includes a conductive resin. According to the above configuration, it is possible to manufacture by applying and supplying a conductive resin using a dispenser. Therefore, the production of the conductive material becomes easy. Further, by kneading the conductive filler and the low expansion material to lower the thermal expansion coefficient of the conductive resin, it is possible to suppress the warpage of the piezoelectric substrate.
- the conductive resin of the inkjet head of the present invention includes one or more conductive fillers selected from the group consisting of Au, Ag, Ni, Cu, carbon, and solder. Is used.
- the inkjet head having the above configuration when Au or Ag is used as the conductive material, the electric resistance of the conductive resin and the electric resistance between the conductive resin and the electrode connected to the driving IC can be suppressed. . As a result, the driving frequency of the voltage applied for driving the actuator can be improved. Therefore, according to the inkjet head having the above configuration, high-speed printing can be performed.
- connection with high reliability and a low connection resistance value can be performed.
- the longitudinal dimension of the conductive filler is not less than 0.1 ⁇ and not more than 30 im.
- the contact area between the conductive fillers of the conductive resin is relatively large, and the size is such that the conductive filler can function as the conductive resin. Therefore, the electrical conductivity of the conductive resin can be improved without causing any inconvenience.

- the electric resistance between the conductive fillers depends on the material of the conductive filler and the conductive filler. It is expected to vary depending on the diameter, adhesive viscosity of conductive filler, width of ink chamber 26, coating width of conductive filler, and continuity between conductive fillers. Therefore, a centrifugal force is applied to the piezoelectric substrate 60 after the application of the conductive resin 10 so that the conductive filler can be kept in a continuous state.

- the thermal expansion coefficient of the conductive resin 1 ° is larger than the thermal expansion coefficient of the piezoelectric substrate 60. Therefore, after the conductive resin 10 is applied to the ink chamber 26 and cured, a concave warp occurs in the piezoelectric substrate 60 in a cross section orthogonal to the direction in which the groove of the ink chamber 26 extends. When a force is applied to the conductive resin 10 in a direction to correct the warp in a later step, separation occurs between the conductive resin 10 and the actuator driving electrodes 27 and 28.

- the polishing is performed by the following steps. First, the warpage generated in the piezoelectric substrate 60 is corrected. Next, the back surface of the corrected piezoelectric substrate 60 is attached to a plate having high flatness with wax.

Therefore, when the polishing is completed (that is, the electrical separation between the ink chamber electrodes is completed), the polished area is extremely increased. As a result, the polishing rate becomes extremely slow. Therefore, it is possible to manage the polishing end position by monitoring the change in the polishing rate.

In addition, portions other than the active area of the actuator are almost unnecessary. Therefore, material costs can be reduced.
- the external connection electrode has no portion extending along the surface of the piezoelectric element. For this reason, it is possible to suppress an increase in capacitance due to a long electrode portion extending from the surface of the piezoelectric element. Thereby, the drive frequency of the actuator can be improved. As a result, high-speed printing can be realized. Further, according to the ink jet head of the present embodiment, it is not necessary to apply a high voltage to improve the driving frequency.
