Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mounts electronic parts,
The present invention relates to a so-called electronic component mounting logic board, and further to a management method for managing such an electronic component mounting logic board.

[0002]

2. Description of the Related Art For a logic board on which electronic parts are mounted, it is necessary to identify the repaired state and the degree of improvement in function level. Conventionally, therefore, for example, as shown in FIG. 7, a display frame (revision mark) 2 for displaying the function level is provided on the substrate 1, and the display frame is marked with a marker 3 or the like. It is common practice to display the functional status of the logic board and manage the logic board.

When managing the identified logic boards by marking such a display frame, particularly in the case of an apparatus in which several kinds of logic boards are mounted, all the logic boards are managed. The operator visually identifies and confirms the marking of the function level, and the information regarding the function level of the logic board is keyed into another management device to be stored.
Alternatively, it was necessary to fill in a management sheet with a pen.

[0004]

However, in the above-described board identification management method according to the prior art, human work such as identification of markings, key input or pen writing is involved, so that there is always an artificial operation. There is a possibility that mistakes will occur. Therefore, a discrepancy may occur between the function level of the actual logic board and the information stored in the management device.
Further, in order to confirm the function level of the logic board that has been built in the inside of the device, it takes time and effort to stop the device again and confirm the marking visually on the display frame on the logic board. Work was needed.

Therefore, in the present invention, in view of the above problems in the prior art, that is, in the conventional information management of the function level of the logic board, the contents of the level information are visually input to the device or transcribed by a person. It eliminates the erroneous input and the labor of work that is caused by such a problem, and the troublesome work of confirming the marking on the logic board by disassembling the device once again and disassembling it. Provides a logic board with electronic component mounting that can automatically recognize level information and reduce erroneous input by a management method that reduces the possibility of inconsistency in level information, and a management method thereof. The purpose is to do.

[0006]

Therefore, according to the present invention, as means for achieving the above object, according to the present invention, first, on a part of the surface of an electronic component mounting logic board on which electronic components are mounted on a circuit board. A level display frame composed of a plurality of frames for identifying a repaired state of the electronic component mounting logic board and a degree of functional level up, and electric wiring is formed under the level display frame, and the circuit board is provided. An electronic component mounting logic board provided with a reading device for recognizing the functional level display provided on the level display frame by further reading the electric voltage level in the electric wiring below the level display frame is provided on the upper side. Proposed.

Further, according to the present invention, in order to achieve the above-mentioned object, the reworked state and the degree of function enhancement of the electronic component mounting logic board are displayed in the plurality of level display frames of the electronic component mounting logic board. A method of managing an electronic component mounting logical board for providing a display for identifying, wherein a corresponding part of the plurality of level display frames is cut out together with electric wiring formed under the level display frame. Management methods have been proposed.

[0008]

That is, according to the present invention, by using the electronic component mounting logic board, the management method of the electronic component mounting logic board is cut out together with the level display frame and the electric wirings formed respectively below the level display frame. The level display frame for identifying the reworked state of the electronic component mounting logic board and the degree of improvement in the function level and the electrical wiring arranged below the level display frame can be made to correspond one to one. Further, according to the above electronic component mounting logic board, the cut electrical wiring can be recognized as a voltage signal by the reading device.
The level information at the time of marking can be automatically and surely read, eliminating the occurrence of erroneous input and the trouble of work, and further, once it is installed in the device, it can be stopped or disassembled again. It is possible to automatically and surely recognize and confirm the level information by the device itself or by using an external management device without any need.

Of the five inputs of 150, the electric wiring 141 in the lower part of the display frame 131 (display frame “1”) cut by punching the hole 160 is cut together with the cutting of the display frame “1”, and therefore, A voltage of the power supply (Vcc) appears on the electric wiring 141 (that is, becomes "High" level). On the other hand, the other uncut electrical wires 142-145
No voltage appears at (low level).

As described above, the five electric wires 142 to 145 input to the reading device (input device) 150 are input.
Indicates that a combination of signals of "High" level and "Low" level appears, and after this substrate is once incorporated in the device, the reading device (input device) 150
Automatically determines the revision mark 13 by judging the combination of the levels of these five input signals.
It is possible to confirm the identification of 0. Furthermore, this recognition can be performed on a program by the central processing unit 170 mounted in the electronic component mounting logic board 100, or by a management device provided outside.

As described above, according to the electronic component mounting logic board 100 according to the above-described embodiment of the present invention, the marking portion which is the revision mark 130 is positioned as a kind of input device in the logic device, and the marking itself is logically processed. By reading it as one of the information directly into the program, recording it, and confirming it, it is possible to eliminate human errors such as visual work, key input and pen writing, reduce the work time, and disassemble the device. You can check the function level of all the mounted boards without.
