Abstract

(57) [Summary] [Purpose] To prevent the copper foil patterns from becoming distorted when a large number of copper foil patterns are arranged on a printed circuit board and experiments or repairs are performed. [Structure] In the present invention, resist treatment is applied to every other adjacent copper foil pattern along the pattern so that a portion of the copper foil pattern is not applied, thereby creating a pattern that can be distinguished from the adjacent copper foil patterns.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a printed circuit board used in electronic equipment.

0002

[Conventional technology]

Copper foil patterns and electric wires are used for soldering parts and inspection jigs. Except for the parts that are electrically connected, all surfaces are resist-treated and have the same color. .

0003

[Problem that the idea aims to solve]

The copper foil patterns of the same color are arranged in parallel, so you can visually follow the copper foil patterns. As you progress, your eyes will shift to other patterns before you know it, making repairs and inspections difficult. It had some serious flaws.

0004

[Means to solve the problem]

In this invention, every other solder resist pattern of the copper foil pattern of the printed circuit board or Every few lines, there is a part where no resist processing is performed, and the pattern is created as a pattern. To be able to distinguish between groups of sounds.

[0005]

[Effect]

If you have to solder the entire printed circuit board in areas that are not treated with resist, If it is, it will be the color of the copper foil itself, and if it is soldered, it will be the color of the solder. When placing patterns by eye, some of the adjacent patterns may be registered. Since no pattern processing is performed, the risk of losing track of the pattern is reduced. Another pattern When tracing by eye, all adjacent patterns have been subjected to resist processing, so it is similar to the current one. This reduces the fear of losing track of the pattern you are trying to follow. Also, by forming each pattern with a different pattern, the soldered parts can be distinguished as a group. Can be separated.

【Example】

FIG. 1 is a diagram showing an embodiment of the present invention, and FIGS. 2 and 3 are enlarged views thereof. Board 1 Copper foil patterns 2a-n are provided in the resist-treated area having non-resist-treated areas 3a-n. Science Department 4 will be established. Non-resist treated areas 3a to 3n are located at every other copper foil pattern 2a to 2n. Alternatively, a non-resist treated portion is provided every two lines so as to form a pattern. In this case the soldering part When visually following the copper foil pattern 2b from 5b to 6b, the adjacent pattern 2 As shown in the figure, a and 2c are copper foil patterns that are partially untreated with resist, so it is difficult to tell them apart. When tracing copper foil pattern 2c by eye, all adjacent copper foil patterns are registered. Because they have been treated with paint, they can be distinguished and are useful when repairing or inspecting boards. Also, identify the soldering parts 7a to n in the middle. It also becomes easier.

[0007]

[Effect of the idea]

According to the present invention, the parts of the copper foil pattern that are not subjected to resist treatment are Since a non-resist treated area was provided on the copper foil as a pattern to distinguish each pattern, it was easy to repair. It is possible to discern the destination of patterns during inspection.

Claims (1)

[Scope of utility model registration request] [Claim 1] The resist of the left and right copper foil patterns of the three adjacent copper foil patterns of the printed circuit board that has been subjected to resist treatment is applied at regular intervals along the portions that are not subjected to resist treatment. A printed circuit board characterized in that copper foil patterns are distinguished by patterns provided.
