(Prior art) Conventionally, such mesh products often consist of a mesh part and a frame-shaped body surrounding the mesh part, and furthermore, the thickness of the mesh part has to be thinner than the thickness of the frame-shaped body. This is preferable in terms of improved pattern accuracy and functionality. Figure 2 A and B are
An example of a method for creating such a mesh fabrication is illustrated. In FIG. 2, metal plate 1
The thickness of the corrosion-resistant film is exaggerated. Actually, the metal plate 1 has a thickness of about 30 to 200 microns. As shown in FIG. 2A, one surface of the metal plate 1 is provided with a corrosion-resistant film 2 corresponding to a mesh part and a corrosion-resistant film 3a corresponding to a frame-shaped body, and the other surface is provided with a frame-shaped body. Only the corrosion-resistant film 3b corresponding to the body is provided, and no corrosion-resistant film corresponding to the mesh portion is provided. If you etch from both sides in this state, the second
As shown in FIG. 2, a mesh product is completed in which the thickness of the mesh portion 5 is reduced compared to that of the frame-like body 4.

However, this conventional method has the following drawbacks. FIG. 3 shows an enlarged view of the boundary between the frame member 4 and the mesh portion 5. As shown in FIG. As a result, the connection between the mesh portion 5 and the frame-like body 4 became weak, resulting in defects in which the mesh portion 5 sometimes detached from the frame-like body 4.

The reason why the conventional method has the drawback shown in FIG. 3C is conceptually shown in FIG. That is, the fourth
The figure assumes that the etching is in the middle of etching, and the etching liquid 10 is sprayed from the spray nozzle onto the other side (in this case, the lower side), but the sprayed etching liquid is sprayed onto the etching surface. There is a tendency for the metal to flow forcefully toward both ends, and to contact the frame-like body 4 at both ends, deeply corroding and dissolving the vicinity thereof (that is, the boundary between the mesh portion and the frame-like body).

(Specific means for solving the problem) That is, the present invention provides a corrosion-resistant film having a shape similar to that of the mesh part to be formed on one surface of a metal plate and a frame-like body having a shape similar to that of the mesh part to be formed on one side of the metal plate. A metal plate having a shape similar to that of the frame to be formed is formed on the other surface, and both sides of the metal plate are corroded and dissolved at the same time using an etching solution to form a frame. In a method for manufacturing a mesh product in which a mesh part and a mesh part are integrated, a side etching phenomenon occurs at a position on the other side corresponding to the corrosion-resistant film applied in the same shape as the mesh part on one side. This method of manufacturing a mesh product is characterized in that simultaneous etching is performed on both sides in a state where an auxiliary resist with a small line width that eventually falls off is provided.

As shown in Fig. 1A, a metal plate 1 is the material
has the same thickness as the frame or the maximum thickness required by the mesh product to be made, and is made of iron, steel, 42 alloy (nickel 42% by weight, balance iron), stainless steel,
Various metals including but not limited to copper, copper alloy, aluminum, molybdenum, tungsten, etc. can be targeted. Photosensitive resist films 6a and 6b are applied to both sides of this metal plate 1. For photosensitive resists, water-soluble photosensitive resins made by adding photocrosslinking agents such as dichromate to polymeric resins such as polyvinyl alcohol, casein, and gelatin are inexpensive and easy to use, but there are also organic solvent-based photosensitive resins. Resins and self-curing solvent-free photosensitive resins can also be used. The latter is generally suitable for forming high resolution patterns. Next, as shown in FIG. 1B, mask originals 7a and 7b are placed in close contact with each other on both sides, and light is irradiated from above and below to expose the photosensitive resist films 6a and 6b. Since the illustrated embodiment uses a negative type photosensitive resist, only the portions irradiated with light are cured, and when developed, the state shown in FIG. 1C is obtained. A feature of the present invention is that an auxiliary resist 9 having an extremely fine line width is provided on the other surface facing the anti-corrosion film 8 corresponding to the mesh portion. That is, the pattern of the anti-corrosion film 8 corresponding to the mesh portion remains as a mesh line width, but the auxiliary resist 9 is much thinner than the pattern, and therefore disappears due to the side etching phenomenon of the etching process. FIG. 1D shows the state immediately before the auxiliary resist 9 peels off during etching. As a result of the peeling off of the auxiliary resist 9, a half-etched state is finally realized on the other surface as shown in FIG. 1E, and the plate thickness can be reduced. However, as shown in FIG. 1E, the boundary portion 12 between the mesh portion 5 and the frame-like body 4 is connected by a gentle slope curve, so it can be said that they are in a strong bond.

(Function) The reason why this happens is conceptually shown in Figure 5.
In the present invention, the etching of the other surface (lower side) by the auxiliary resist a proceeds separately for each mesh, and the etching liquid 10 injected from below is concentrated at both ends as in the conventional method. This results in corrosion and dissolution of the individual etched areas without any flow. The auxiliary resist 9 prevents the progress of local etching at the boundary between the mesh portion and the frame-like body.

That is, R=D/F, and the width S of the corrosion-resistant film 11 is determined by the etching factor F and depth D. In the present invention, the width S of the auxiliary resist may be set to a size that disappears by side etching, but practically it is set to approximately S=D/F. It is known that F=1.5 to 3.5 under normal spray etching conditions, so let's assume F=2.5 and etching depth D=
Assuming 0.1 mm, the width S of the auxiliary resist can be derived, for example, as follows: S=0.1/2.5=0.04 mm.

The form of the auxiliary resist may be one auxiliary resist 9a as shown in FIG. 7A, or a plurality of auxiliary resists 9b as shown in FIG. 7B. By using a plurality of auxiliary resists 9b, the cross-sectional shape of the mesh 5 becomes a good shape close to a rectangle, and the etching depth can be adjusted by adjusting the density of the auxiliary resists, so that the thickness of the mesh portion 5 can be adjusted. can also be controlled.

(Effects of the Invention) According to the present invention, by forming the auxiliary resist on the other surface of the mesh part, the connection between the mesh part and the frame-like body becomes strong, and the mesh part is prevented from peeling off from the frame-like body. The occurrence of defective products is minimized. Furthermore, if the auxiliary resist is formed into a plurality of pieces, there is an advantage that the cross-sectional shape and thickness of the mesh portion can be controlled and an article having a desired shape can be manufactured.
