Abstract

PROBLEM TO BE SOLVED: To easily and precisely identify a corresponding component from identification code by printing the identification codes on a board main body in forms adjusted to the forms of the components to be mounted. SOLUTION: A prescribed electric circuit is printed on the board main body 11 and a plurality of components 12 are mounted on the prescribed positions of the electric circuit by soldering. The identification codes 13 corresponding to the components to be mounted are printed on the side of the components mounting positions of the board main body 11 with silk printing and the like. The identification codes 13 signify the corresponding components by combining plural alphabets and numbers. A series of character groups are printed in sizes and forms, which are adjusted to the sizes and the forms of the corresponding components 12. When a defective article exists, the components 12 can easily and precisely be recognized by comparing the size and the form of the recognition code 13 and those of the component 12 in addition to the collation of the mark itself of the mark 13 of the code with the component 12 for recognizing whether the component 12 is correct or not.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed circuit board on which a plurality of components are mounted by soldering or the like, and more particularly to a printed circuit board on which an identification mark for recognizing a component mounting position is printed.

[0002]

2. Description of the Related Art As a printed circuit board of this type, a printed circuit board as shown in FIG. 2 has been conventionally put into practical use.

On this printed circuit board, an identification symbol 3 corresponding to the component 2 is printed at a position close to the actual component mounting position on the substrate body 1, and when the component is replaced, etc.
Based on the above, the worker can correctly mount the component 2. The identification symbol 3 printed on the substrate body 1 is
It is composed of a combination of a plurality of characters or symbols.

This technology is disclosed, for example, in "Transistor Technology", CQ Publishing Co., September 1995, page 211, Photo 9-2.
Etc.

[0005]

However, in the above-mentioned conventional printed circuit board, since the identification symbols printed on the substrate body are only the constituent characters and the order or combination of the constituent symbols changed, the replacement of parts is not possible. At this time, for example, when a solder defect or a component failure is found in the inspection process, and the worker removes the component and replaces it with a new component (particularly, when replacing a plurality of components at the same time), It is difficult to immediately find the corresponding component from the printed identification symbol, and it takes a lot of time to replace the component.

Therefore, the present invention intends to provide a printed circuit board capable of easily and accurately recognizing the corresponding component from the identification mark printed on the substrate main body and improving the mounting work efficiency of the component. To do.

[0007]

As means for solving the above-mentioned problems, the invention of claim 1 is such that a plurality of components are mounted on a substrate main body, and the mounting positions of these components are associated with each other. In the printed board on which the identification mark of the component is printed, the identification mark is printed on the substrate body in a shape matching the shape of the component to be mounted. Since the shape of the identification symbol matches the shape of the component to be mounted, the operator can recognize the mounted component also from the shape of the identification symbol.

According to a second aspect of the present invention, a plurality of components are mounted on the substrate main body, and identification symbols of the components are printed corresponding to the mounting positions of these components. The symbols are printed on the board body in a size that matches the size of the components to be mounted. Since the size of the identification symbol matches the size of the component to be mounted, the operator can recognize the mounted component also from the size of the identification symbol.

BEST MODE FOR CARRYING OUT THE INVENTION Next, one embodiment of the present invention will be described with reference to FIG.

FIG. 1 is a plan view of a printed circuit board according to the present invention, in which a predetermined electric circuit (not shown) is printed on a substrate body 11 of the printed circuit board, and a predetermined position of the electric circuit. A plurality of components 12 are mounted on the substrate by soldering. Further, on the side of the component mounting position of the board body 11, an identification symbol 13 corresponding to the component to be mounted is printed by silk printing or the like.

Here, the identification symbol 13 is designed to mean a corresponding component by combining a plurality of alphabets and numbers, and this series of character groups further includes the size and shape of the corresponding component 12. It is printed in a size and shape that suits.

The component 12 is basically mounted on the substrate main body 11 by an automatic mounting apparatus. However, if a solder defect or a component failure is found in the inspection process after the mounting, the defective component is detected. Separate parts 12 manually by the operator
Is replaced by

At this time, the operator looks for the new component 12 by relying on the identification symbol 13 printed on the substrate body 11,
The component 12 is soldered to a predetermined position on the substrate body 11. When searching for a new component 12, the components are roughly classified based on the shape and size of the identification symbol 13 (of the character group). Since the judgment can be made, a new part 12 can be found quickly. Also, the part 12
In order to confirm that the identification number 13 is correct, the shape and size of the identification symbol 13 and the component 12 can be compared with each other in addition to the comparison between the symbol itself of the identification symbol 13 and the component 12. Can be accurately selected without error.

Therefore, according to this printed circuit board,
The time required for parts replacement, etc. can be shortened and the production efficiency is greatly improved.

[0015]

As described above, according to the invention of claim 1, the identification symbol for identifying the component to be mounted on the substrate body is printed on the substrate body in a shape that matches the shape of the component to be mounted. The operator can easily and accurately recognize the corresponding component from the identification symbol, and as a result, the time required for component replacement and the like can be shortened and the production efficiency can be greatly improved.

According to the second aspect of the present invention, the identification mark is printed on the substrate body in a size corresponding to the size of the component to be mounted. Similarly, the operator can easily identify the corresponding component from the identification mark. , And can be accurately recognized.
