【発明の詳細な説明】
本発明は印刷用のインクジェットプロ７り等に用いられ
る微細孔径のノズルの製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a nozzle with a fine pore diameter used in an inkjet printer for printing and the like.
一般に、印刷用のインクジェットには引抜きチューブが
用いられるが、φ０．０５ａｍ以下の微細孔径の加工が
できず、微量のインク噴射用ノズルとしては不適当であ

にニッケルめっきを行い電着完了後金Ｈ線のみ腐食熔解
させる方法等が提案されているが、前者にあっては製造
コストが高く、また後者に。Generally, drawn tubes are used for inkjet printing, but they cannot be processed into micropores with a diameter of φ0.05 am or less, making them unsuitable as nozzles for ejecting small amounts of ink. Therefore, methods have been proposed, such as processing the metal hole shape using a laser beam, or nickel-plating the gold B wire and corroding and melting only the gold H wire after electrodeposition, but the former method requires high manufacturing costs, and the latter method requires high production costs. .
あっても加工後の腐食処理を必要とすることなどから製
造工程が複雑化するという問題があった。Even if there were, there was a problem in that the manufacturing process would be complicated due to the need for corrosion treatment after processing.
本発明はかかる点に鑑がみてなされたものであって、そ
の目的とするところはめっきによる製造で低コスト化が
図れ、しかも後処理が不要な微量噴射用ノズルの製造方
法を提供するにある。The present invention has been made in view of these points, and its purpose is to provide a method for manufacturing a micro-injection nozzle that can be manufactured by plating at low cost and that does not require post-processing. .
以下、発明を図の実施例に基づいて詳述する。Hereinafter, the invention will be explained in detail based on the embodiments shown in the drawings.

０〜２．抛−のステンレス鋼板を用いるものとする。First, as shown in Fig. 1, two banks 7 (width is, for example, 10 to 15 ms) are formed on the substrate 1 by hardening film by coating with a water-soluble photosensitive liquid.Firstly, the substrate is sandwiched between the banks 7. 1
Primary plating on the surface in a nickel sulfamate bath 2
(The thickness is, for example, 0.015 m+*) and use this as the nozzle base. Note that the thickness of the substrate l is 1.
0-2. A stainless steel plate shall be used.
次に第２図のように基板１を水洗・乾燥させたのち一次
めっき雇２上にステンレス鋼線３ （径は例えばφ０．

。Next, as shown in FIG. 2, after washing and drying the substrate 1 with water, a stainless steel wire 3 (with a diameter of, for example, φ0.
03mm) and fix both ends with screws 8.

次めっき層２及び土手７と十分に密着するようにする。Thereafter, a solvent type photosensitive liquid is applied to the surfaces of the bank 7 and the primary plating layer 2 to a thickness of, for example, o, ooslI to 0°Of+m to form photosensitive resin N4. In this case, the photosensitive resin layer 4
is made to completely cover the stainless steel wire 3 and to be in sufficient contact with the primary plating layer 2 and the bank 7.

完成させる。Next, after drying the photosensitive resin layer 4, a Bakun film (
The exposed nickel surface corresponding to the opaque part of the primary pattern film is divided into exposed B1!5 and exposed lζ9 as shown in FIG. An oxide film has been formed, and this oxide film part 10 is removed with hydrochloric acid water, and electrodeposited again in a nickel sulfamate plating tank under the same conditions as the primary plating to form a secondary plating layer 6 (w, for example). 0°013R11I) is formed to adhere closely to the primary plating layer 2 and cover the stainless steel wire 3.Finally, the fixation of the stainless steel wire 3 is released as shown in FIG. 4, and the plated eyebrow 2. 3 from the substrate 1 and the stainless steel wire 3 is pulled out to complete the nozzle A.

Furthermore, since the tip of the nozzle A is formed in a loose shape that is blocked by the hardened film part of the water-soluble photosensitive liquid constituting the bank 7 and the photosensitive resin W14, the shape is uniform, and therefore the direction of the ejected ink is The gender can be the same.

５０℃の温度にて３０分間ベーキング処理をする。In addition, in order to improve the adhesion of the water-soluble photosensitive liquid to the substrate, a 10% aqueous solution of hydrochloric acid and nitric acid was heated to a temperature of 40°C to 45°C.
After soaking for 5 minutes, washing with water and drying, apply a water-soluble photosensitive liquid. The thicker the photosensitive coating, the better, so 0.0
The original plate was adhered to a thickness of 15 mm, exposed and developed using a high-pressure mercury lamp.
Baking is performed at a temperature of 50° C. for 30 minutes.

。The liquid composition of sulfamic acid nickel plating was 450 g/λ of nickel sulfamino acid, 40 g/i of boron M, and 20 cc/u of surfactant, and the plating conditions were as follows: temperature: 48°C to 50°C;
pH 4,0-4. S, the current density is 4 to 6 A/drf.

上、コストの低減が可能になるという効果を奏する。As mentioned above, after forming the primary plating layer that will become the nozzle base on the substrate, a fine-diameter stainless steel wire is stretched over the primary plating layer, and then the stainless steel wire is covered with the primary plating layer. Apply photosensitive 441 greasy eyebrows to the surface of the plating layer, and then apply photosensitive 4kJIli? on predetermined areas. Expose layer 81
After the first image, it is removed to expose the primary plating layer and the stainless steel wire, and then a secondary plating layer is formed on this exposed area and electrodeposition bonded to the primary plating layer, and the stainless steel wire is covered. Afterwards, the plating layer is peeled off from the substrate and stainless steel is created! Since Izumi Okamoto is drawn from the plating layer, ink reservoirs etc. can be manufactured as one piece, and since the steel wire is drawn, post-corrosion treatment is easier compared to corroding and removing the steel wire. As a result, mass productivity can be improved and costs can be reduced.
