Abstract

PURPOSE:To perform etching with extremely high accuracy in the stage of etching a metallic plate and forming a pattern, by drawing the contour added with a side etching rate to the contour of the required pattern and making the contour parts thereof discontinuous. CONSTITUTION:Picture lines 15 to be not formed with an etching resistant film are drawn with <=200mum fine lines by having an offset rate for side etching on the contour of metallic lines 13 when the etching resistant film for forming patterns is formed in the stage of forming the lines 13 of the required pattern by etching on a metallic film. The lines 15 in this case are made discontinuous in the parts 17 corresponding to the corner parts 16 of the lines 13 or the parts where the adjacent parts 15 are in proximity to each other. If the metallic plate is etched by using the etching resistant film consisting of such original plate, the steel plate is etched easily to the sharp shape with high quality.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing an etched product.

-1- Use a corrosion-resistant film on metal plates! Target IJ: iL

There are 8 types of processed products (made by C) and 6 types, but the remaining 1 unit;
There are m pieces of conductive parts such as t, ) (↑ ↑ flat electric plate (, 1, referred to as ritrum, shown in Fig. 1).
A pattern consisting of a large number of thin branch-like metal strips 2 is placed on the thin metal sheet metal (unnecessary part J) 4 , I bar f tuzo 1; 1 mounting part 3! no J bar chitsubu dotsuirebon 7'-rung wisdom's digit) person (・connected).

In this way, the size of 41 metal strips 2 is IR-(mirror 1-1 b), and for 1161 metal plates in h-bit pattern 1.1, a large number of tr b(- Since it is a state in the state of “11 huhmia-), it is (only in the sign, it is ゛。) 1 (1) 1 (Sema -C strictly needed 5J.

This 1=li 'j rim/l! To form and form J on one piece, you need 'J/! on a metal machine! l1
The most common method is to form a corrosion-resistant film and remove the metal in unnecessary parts using a chemical method. Shown in Figure 2!JJ
, Sea urchin, the shape of the corrosion-resistant lIQ = 2 - shape is taken as a virtual line and the required pattern is accurately drawn. (
b. In the product actually obtained by connitting, as shown by the solid line, it is preferable that the 'corner of the metal strip 2 is rounded by lead-touching to create a sharp corner.

When using the II version for forming a corrosion-resistant film,
Conventionally, a method of filling in unnecessary parts (hatching method) or drawing an outline with a relatively thick line (thick outline>1<) has been used to create the necessary pattern.

In addition, the line width and shape change, especially the shape change caused by the above-mentioned part of the cope, and the third
A special pattern 5 called a hirif shown in the figure may be added to a corner part, or a bridging part 6 (Patent Application Publication No. 26 of 1980) may be added to a corner part as shown in
'169) 3rd Duke+17. Attempts have been made to solve the problem by adding backups other than the original drawings, such as preventing the shape change due to nri-aidedepunk. . However, 62 people in the etching process were able to produce etched products using the original plates created by J.
If it is, the dense part of the pattern and the butter 3

- The fatigue of the etchant during etching is significantly reduced, and the life of the etchant can therefore be extended, making it possible to produce etched products that are economically advantageous. The purpose is to provide Xli h 74.

Corresponding to this point, the method for manufacturing one product according to the present invention involves "tzonging" a metal plate using a corrosion-resistant film.

32. In the method, the original plate for forming the corrosion-resistant film is guided along the outline of the required pattern, and the image area for non-corrosion-resistant film formation along the outline of the required pattern is drawn as a thin line. , and draw the above-mentioned line part as above-mentioned pattern 9.
It is characterized in that in a part of the corner or in a part where the adjacent image parts come close to each other, 116 b are discontinuously used.

J, J, and SuC are three people, Sea 6 - connection ψ, corrosion part I J3 inside is metal strip 13 q! The circle of JR is lost, and the discontinuous part of the picture 11AN115 is removed, and the corroded part 18 is continuous,
The unnecessary portion 12 is separated from the necessary metal strip 13 by the corroded portion 18 and falls 11v2, finally obtaining the desired metal strip 13.

As described above, in the method of manufacturing an etched product of the present invention, it is necessary to create shapes such as fillets and cross-linked parts in order to obtain the desired product shape.
It is extremely easy to create an original version because there is no need to change patterns that are not in the original version, and the real pain is eliminated by deleting part of the original pattern. In addition, it is possible to easily inject high-quality tethered products with the required thin IF pattern based on the standard.Furthermore, etching is performed only within the narrow corroded area 18.
Since it is not necessary to remove all unnecessary parts by corrosion, the fatigue of the etchant is greatly reduced, and the life of the etchant can be extended, which is also economically advantageous.

The arrangement of the image area 15 and the discontinuous area is not limited to that shown in Figure 8. , eel 8(・t no j′ old I(
