Description

Description: TECHNICAL FIELD The present invention relates to creation of data for manufacturing a wiring inspection jig for a printed wiring board, and more particularly to a device for creating pin planting diagram data for a wiring inspection jig. .

[Conventional technology]

Currently, when performing a wiring inspection of a printed wiring board, as shown in FIG. 4, soldering of component mounting holes (hereinafter referred to as through holes) 8 of the inspected printed wiring board 7 and leadless components is performed. An inspection jig 11 is used in which an inspection pin 12 connected to a wiring inspection machine is erected in a penetrating state on an insulating plate at a position corresponding to a conductor portion (hereinafter referred to as a pad) 9 for use. That is, the printed wiring board 7 is pressed against the pin 12 of the inspection jig 11 to supply the current from the inspection machine to the through hole 8 in contact with the pin 12,
The current supplied from the inspection machine is transmitted to the other through hole 8 connected to the through hole 8 and the line 10 through one pin 12, and is taken out from the other pin 12 through the through hole 8 and sent to the inspection machine. The conduction state between the through holes 8 and 8'is checked.

To make the above-described inspection jig 11, the pin implantation shown in the correspondence between the position of the insertion hole provided for penetrating the pin 12 in the base material of the inspection jig 11 and the type of the pin 12 to be implanted. A standing figure is required. Hereinafter, a conventional means for creating such a pin plotting diagram and a method for creating the inspection jig 11 using the pin plotting diagram will be described with reference to the drawings.

FIG. 5 is a block diagram showing a configuration of a conventional creating apparatus, and FIG. 6 (a) is an operation method and an inspection jig of the conventional creating apparatus.
FIG. 6 (b) is a flowchart for explaining the creation method of 11.
FIG. 7 is a flowchart explaining the operation of the pin data creating unit 13 of the conventional creating apparatus, FIG. 7 is a conceptual diagram of data explaining the operation of the conventional creating apparatus, (a) is a state before processing,
(B) is a state after processing, and FIG. 8 is a correspondence diagram showing the relationship between the name of the pin 11, the symbol name, and the drawing shape.

First, when the operator inputs the position data of the through hole 8 and the pad 9 of the printed wiring board 7 to be inspected and the attribute data thereof to the data storage unit 2 via the data input unit 1, the operation of the pin data creation unit 13 is started. To do.

The pin data creation unit 13 reads the position data 5-1 and 5-2 and the attribute data thereof while sequentially accessing the data storage unit 2, and the intervals between the position data that are close to each other and the through holes included in those attribute data. , Select the pin PRB-01, PRB-02 that is most suitable for the position data 5-1 and 5-2 read in consideration of pad type, hole diameter, and manufacturing gap, and select the pins PRB-01, PRB-02 in advance. The symbol names D01 and D02 for drawing, which are in one-to-one correspondence with the types, are added to the attribute data and stored in the data storage unit 2. The symbol name, not the pin name, is added to the attribute data for the purpose of making the data versatile so that the plotter used for drawing in the next process can also draw the pattern information output from other systems. For all position data,
When the type of the pin 12 is selected and the symbol name is added, the operation of the pin data creating unit 13 ends.

In the next step of drawing the pin data, according to the relationship between the symbol name and the shape in the correspondence table of FIG. 8, for each symbol name of the pin data output via the data output unit 3,
Drawing is performed by specifying the drawing shapes 14-1 and 14-2.

In the step of planting the last pin, the pins PRB-01 and PRB-02 corresponding to the position plotted on the pin planting diagram are inspected according to the relationship between the pin name and the drawing shape in the correspondence table of FIG. Jig 1
The inspection jig 11 is obtained by erection in the insertion hole provided in the base material 1.

[Problems to be solved by the invention]

In the case of making an inspection jig using the pin planting diagram data created by the above-mentioned conventional device, there are the following problems.

(B) If a drawing shape different from the corresponding drawing is specified in the pin data drawing process, there is a possibility that the pin will be erroneously planted in the pin setting process.

(B) In the process of planting pins, work is performed while comparing the pin planting diagram and the correspondence diagram, which is inefficient.

There is a problem.

In contrast to the conventional device described above, the present invention has an original content of outputting pin planting plan data including a correspondence table of pin names and drawing shapes as data.
