ている。 Recent thick film printing requires high precision and fineness, and various types of screens used for printing have been developed for high precision. FIG. 1a is a plan view showing a part of the suspended metal mask, and FIG. 1b is a sectional view taken along the line X--X in FIG. 1a. As shown in FIG. 1, this screen is made by bonding stainless steel meshes 1, 1' and a printed pattern layer 2 with a plating layer 3. For this reason, the wire diameter of the stainless steel mesh increases by the thickness of the plating layer. For example, stainless mesh diameter 0.04
When using a stainless steel mesh with a mmφ mesh pitch of 0.13mm, the mesh diameter will be 0.06mmφ, which is
The aperture ratio of 48% drops significantly to 29%. As the aperture ratio decreases, the amount of filling of printing paste decreases, resulting in a thinner printed film. Further, since the mesh diameter is large, the printing paste does not wrap around easily, and the portion below the mesh line becomes even thinner, which may cause disconnection or pinholes depending on the printing paste. For this reason, even if a plate can be made with high precision, its range of use in actual printing is narrow. In particular, it has the disadvantage that it cannot be used for dielectric layers that require a thick printed film and where pinholes are a problem.

After adhering to the stretched screen plate with a plate-making emulsion, a photomask is aligned with the metal printing pattern from the opposite side of the base metal foil through the plate-making emulsion and exposed using a photo printing method, and the emulsion is polymerized. harden. After that, the metal foil of the base material is dissolved and removed, leaving the metal printed pattern area, and then the emulsion layer other than the printed pattern area is completely removed, dried, and exposed again to completely harden the emulsion layer in the printed pattern area. In this way, a printing screen is obtained in which the metal printing part and the stainless steel mesh are integrated into one body.

かつた。 A specific embodiment of the present invention will be explained with reference to FIG. Copper and copper alloy base material 4 (roll material, plated foil) with a thickness of 30 to 40 μm was treated with a commercially available pretreatment agent (trade name: Nutra Clean (manufactured by Shippray Japan Co., Ltd.), and then 8% (Vol. %) Pickled with hydrochloric acid, washed with water, and immersed in isopropyl alcohol. After removing from isopropyl alcohol and drying at 80 to 120℃ and cooling, apply a photoresist or dry film to a photoresist film 5 with a thickness of 2 to 35 μm as shown in Figure a.
After forming on the base plate 4, it is exposed using a photomask (not shown) and developed to form a pattern as shown in figure b, and then a plating resist is formed on it as shown in figure c. A nickel plating layer 6 is plated to a thickness of 3 to 40 μm. Next, the substrate after the process shown in Figure c above is pressure-bonded to the stainless steel mesh 1 and bonded with plate-making emulsion 7, and then heated at 40°C to 50°C.
Dry with. After drying, using a photomask 8 with the white and black inverse of the photomask used in the step shown in Fig. b, it is aligned with the metal pattern of the nickel plating layer 6 and exposed, and cured as shown in Fig. d. Next, as shown in Fig. e, the copper base material 4 is etched with an etching solution that can dissolve only the copper base material 4 without dissolving the stainless steel mesh 1 and the nickel plating film 6 (for example, a sodium chlorite-based etching solution). Dissolve and remove. At this time, the unhardened emulsion 7 is removed, but if there is any residue remaining, it is completely removed during washing with water. As shown in Figure f, the unhardened emulsion 7 is removed and opened. Thereafter, after drying again at 40 to 50°C, the emulsion portion 7 is sufficiently exposed to ultraviolet light to harden the film. The screen made by this method has a mesh aperture ratio of 40% or more, and the printed pattern is a metal pattern formed from a nickel plating layer. Furthermore, the method of the present invention allows pattern formation on a framed stainless steel mesh, resulting in excellent dimensional accuracy. With the method of the present invention, the pattern external dimension is 160×
A 100 (mm) screen was made and used to form an insulating layer in multilayer printing, resulting in a printed film thickness of 40μ (after firing).
It was found that the printing accuracy was sufficiently satisfactory, as the positional deviation was as small as ±20μ, and the pressure resistance was sufficient.

クの応用範囲が広くなつた。 As explained above, conventional metal masks cannot be used for insulating layer printing in multilayer printing or thick etching resists due to the small aperture ratio of the mesh, but the screen of the present invention makes it possible, has a long life, Metal masks, which have the advantage of high dimensional accuracy, have a wider range of applications.
