ドは製作されるものである。 The head for an inkjet printer is formed by bonding together a substrate with ink passages and a top cover that serves to transmit signals from a piezoelectric element, and its general structure is as shown in Figure 1. It is something. Here, Fig. 1 a shows the top cover and the first
Figure b shows the respective substrates, and since the upper cover 1 is required to have appropriate mechanical strength and water resistance, it is usually manufactured using materials such as alumina, mullite, ceramic, or glass/ceramic.
A piezoelectric element 5 is attached to the upper lid 1. On the other hand, the substrate has a double structure with a glaze layer 3 formed on the top surface of the base substrate 2, and the base substrate 2 has appropriate mechanical strength and water resistance, has good dimensional stability, and has good adhesion with the glaze material. Good materials are preferred;
Generally, glass/ceramic or glass/ceramic is used, and lead oxide (PbO) based glass is mainly used as the glaze material. Ink passages 4 are formed on the substrate by etching, and then the top cover and the substrate are bonded using an adhesive that is used at a relatively low temperature such as epoxy or acrylic, or a material that melts and bonds such as a low-melting point glass paste. Heads for jet printers are manufactured.

ている。 However, when bonding the top cover and the substrate, conventionally,
For example, as shown in FIG. 2, there is a method (a) in which adhesive is applied to the entire surface of the upper lid 1 and the adhesive is bonded to the substrate (b), or as shown in FIG. A method is used in which the coating is applied and then bonded to the upper lid 1. However, the method shown in Figure 2 has the disadvantage that the adhesive flows or drips into the ink channel during pressure bonding, easily causing clogging. Since they are small, there is a risk that even a small amount of flow may cause clogging, and countermeasures are desired. In addition, the method shown in FIG. 3 is an attempt to solve the above-mentioned drawback by realizing an adhesive method in which no adhesive is present directly above the ink passage, but the width of the protrusion forming the ink passage is large. Usually 60
Since the area is very narrow, about 70 μm, it is technically very difficult to apply adhesive only to this area. Note that in FIGS. 2 and 3, the same reference numerals as in FIG. has been done.

The glaze layer 13 is formed by baking at 860°C for 30 minutes.
(b) Next, etching is performed using a hydrogen fluoride-sulfuric acid (HF-H 2 SO 4 ) based etching solution to form fine ink passages 14 having the dimensions described above (c). On the other hand, a very smooth glass plate 17 is coated with a low melting point glass paste 16 by spin coating or spraying (d), and the glaze substrate produced in the above manner is pressed onto this surface (e). By this method, the adhesive is inverted onto the glazed substrate (f), and a separately prepared upper cover 13 is pressed onto it, and while applying pressure,
The bonding is completed by baking at 400-600℃ (g). With this bonding method, no adhesive is present directly above the ink passage, so clogging due to adhesive flowing in can be avoided.
