DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a printed wiring board and a component mounter.

[0002]

2. Description of the Related Art Conventionally, there has been a case where a plurality of types of mounting boards differing only in the combination of components to be mounted are produced using one type of printed wiring board having the same wiring pattern. In this case, the type of the mounting board is identified by printing a different identification number on the printed wiring board in advance, or attaching a seal with the identification number printed thereon.

FIG. 6 is a flowchart showing a process of mounting components on a printed wiring board on which an identification number is printed.
FIG. 7 is a flowchart showing a process of performing a mounting check of a printed wiring board on which components are mounted. Note that FIG.
In FIG. 7, four types of substrates 1 to 4 having different identification numbers printed on the same printed wiring board are used.

First, one of the substrates 1 to 4 is selected according to a production instruction (step S21). If the selected board does not meet the production instruction, the board is selected again from among the boards 1 to 4 (step S22). On the other hand, if the selected board is in accordance with the production instruction, the board is set in the component mounter (step S23), a mounting program is set in the component mounter, and components are mounted on the board (step S24,
S25). Then, after the component mounting by the component mounter is completed, the mounted components are visually checked according to the parts list of the mounting board for which production has been instructed. The mounting program is reset (step S26). If the mounting program is in accordance with the production instruction, after performing a manual mounting process of mounting components manually, an automatic soldering process is performed (steps S27 and S28). Then, after a post-attachment step of mounting the post-attached parts and soldering the parts, a finishing step is performed (steps S29 and S30).

Next, as shown in FIG. 7, a mounting board on which components are mounted in each of the above-described steps is set in a board checker, and a mounting check program is set in the board checker. Step S31, S
32, S33). If the operator determines that the mounting check program is not in accordance with the production instruction based on the display of the board checker or the like, a correct mounting check program is reset (step S34). In addition, if the mounting check program is in accordance with the production instruction, the process is terminated if the result of the mounting board check passes, while the mounting board is corrected if the result of the mounting board check fails. Then, the mounting board is checked again (steps S35 and S36).

In this way, a person visually judges the identification number printed on the printed wiring board, and checks whether or not the mounting board is in accordance with the production instruction.

[0007]

However, if a printed wiring board on which an identification number is printed in advance is used to identify a mounting board on which different components are mounted on the same printed wiring board, the type of the printed wiring board is reduced. Since the number of printed wiring boards increases, it takes time and effort to select a board for which production has been instructed. In addition, there is a possibility that an error may occur in selecting a printed wiring board, and there is a problem that management cost and printing cost increase. On the other hand, when an identification seal is used, there is a problem that a seal fee is required, and the labor and time required to apply the seal and the management of the seal are required.

When the circuit element is mounted, the identification jumper is mounted on the jumper mounting portion so that the identification number can be identified by an identification number or the like. Therefore, since a plurality of types of mounting boards that can be identified by one type of printed wiring board can be produced, a plurality of printed wiring boards on which identification numbers are printed for each combination of circuit elements to be mounted are prepared, and according to a production instruction. Therefore, it is not necessary to select a printed wiring board, and it is possible to prevent an erroneous selection of the printed wiring board. Further, the type of the mounting board can be identified without using a seal for identifying the type of the printed wiring board, and the sealing and sealing work can be eliminated, thereby reducing the production cost. In addition, by mounting the identification jumper on the jumper mounting portion so that a plurality of types of mounting boards having different combinations of circuit elements to be mounted can be identified by identification numbers or the like by numbers or characters by 7-segment display, Even if the circuit elements mounted on the same printed wiring board are slightly different and are not easily identifiable, they can be easily identified by an identification number or the like indicated by an identification jumper. Furthermore, when performing a mounting check on a plurality of types of mounting boards with different combinations of circuit elements to be mounted by the board checker, the mounting state of the identification jumper is electrically identified by the identification circuit, and the type of the mounting board is determined.

An identification number or the like represented by a jumper mounted on the mounting portion and the printed wiring board on which a desired circuit element is mounted definitely correspond one-to-one. Therefore, there is no discrepancy between the identification number of the printed wiring board and the mounted circuit element.

Further, the component mounting machine according to claim 3 is the same as claim 2.
In the component mounter, one non-separable program is set in accordance with the combination of the circuit elements mounted on the printed wiring board. Based on the program, the identification jumper is mounted and the circuit element is mounted. And a control means for controlling so as to perform a series of operations.

According to the component mounting machine of the third aspect, the control means performs a series of mounting of the identification jumper and the circuit element by one non-separable program, and outputs the identification number and the like by the identification jumper. Since the corresponding mounting program is integrated, the circuit element is always mounted according to the identification number, and if the mounting program is erroneously different from the one specified for production, the identification number is also different. Can immediately determine the error.

Next, in step S2, a mounting program corresponding to the mounting board instructed to produce by the control unit 11 of the component mounting machine 10 is set. Then, components are mounted in step S3. At this time, before mounting the components, first, a jumper for identification is mounted on the jumper mounting section 2 (shown in FIG. 2), and the identification number of the mounting board for which production has been instructed is displayed.

Next, after mounting the above-described identification jumper and components, in step S4, the numbers (“0” to “9”) represented by the jumpers mounted on the jumper mounting section 2

In the above embodiment, the board checker 20 reads the number represented by the identification jumper by the identification circuit provided on the back surface side of the jumper mounting portion 2 of the printed wiring board 1, and reads it according to the production instruction. It is determined whether or not the mounting board of the jumper, jumper identification means for reading the number represented by the identification jumper from the identification circuit,
Switching means for automatically switching a mounting check program such as a board checker based on the output of the jumper identifying means may be provided. In this case, the setting error of the mounting check program can be prevented, and the trouble of setting the program can be saved.

Further, in the above-described embodiment, instead of the jumper mounting part 2 for identification of the printed wiring board 1, the component mounting machine has a function of printing an identification number or the like by using a laser, and the identification mark is provided. May be performed in series with the step of printing the substrate using a laser and the step of mounting the circuit element. In this case, when producing a plurality of types of mounting boards in which combinations of circuit elements mounted using one type of printed wiring board are different, a laser is used when mounting components so that the type of the mounting board can be identified. Print identification marks. Therefore, since a mounting board that can identify the type can be produced with one type of printed wiring board, a plurality of printed wiring boards on which marks are printed for each combination of components to be mounted are prepared, and the printed wiring board is printed in accordance with a production instruction. There is no need to select a board, and it is possible to prevent mistakes in selecting a printed wiring board, and it is possible to reduce the management cost of the printed wiring board and the printing cost. In addition, the type of the mounting board can be identified without attaching a seal indicating an identification number or the like on the printed wiring board, thereby eliminating the need for a seal or sealing work, thereby reducing costs.
