DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the creation of data for manufacturing a wiring inspection jig for printed wiring boards, and particularly relates to an apparatus for creating pin planting diagram data for a wiring inspection jig. .

[Conventional technology]

Currently, when inspecting the wiring of a printed wiring board, as shown in FIG. An inspection jig 11 is used in which an inspection pin 2 for connecting to a wiring inspection machine is installed in an insulating plate in a penetrating state at a position corresponding to a conductor portion (hereinafter referred to as a pad) 9. In other words, the printed wiring board 7 is pressed against the pin 12 of the inspection jig 11, and the current from the inspection machine is supplied to the through hole 8 in contact with the pin 12, or the current supplied from the inspection machine is transferred to one side. pin 12
It is transmitted to the other through hole 8 connected to the through hole 8 and the line 10 through the through hole 8, and is taken out from the other pin 12 through the through hole 8 and sent to an inspection machine.
, 8' is checked.

In order to make the above-mentioned inspection jig 11, it is necessary to make a pin placement that indicates the correspondence between the position of the insertion hole provided for inserting the pin 12 into the base material of the inspection jig 11 and the type of pin 12 to be planted. A blueprint will be required. A conventional means for creating such a pin-embedding diagram and a method of creating the inspection jig 11 using the pin-embedding diagram will be described below with reference to the drawings.

FIG. 5 is a block diagram showing the configuration of a conventional production device, FIG.
1 is a 70-chart explaining the operation of the pin data creation unit 13 of the conventional creation device, and FIG. (b) is the 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 drawn shape.

First, when the operator inputs the positional data and attribute data of the through holes 8 and pads 9 of the printed wiring board 7 to be inspected into the data storage section 2 via the data input section 1, the operation of the pin data creation section 13 starts. do.

The pin data creation unit 13 reads the position data 5-1, 5-2 and their attribute data while sequentially accessing the data storage unit 2, and calculates the interval between adjacent position data and the through hole included in the attribute data. , the optimum pin pgs-oi for the position data 5-1°5-2 read taking into account the pad type, hole diameter, and manufacturing gap,
Select FRB-02.

A symbol name DOI for drawing that is previously associated one-to-one with the types of pins PR, B-01, and FRB-02.

DO2 is added to the attribute data and stored in the data storage unit 2. Symbol names are added to the attribute data instead of pin names in the plotter used for plotting in the primary process, with the purpose of making the data more versatile so that pattern information output from other systems can also be plotted. When the type of pin 12 is selected and a symbol name is added to all the position data, the operation of the pin data creation unit 13 ends.

In the step of drawing the next pin data, for each symbol name of the pin data outputted via the data output section 3, according to the relationship between symbol name and shape in the correspondence table of FIG.
Designate drawing shape 14-1.14-2 and draw.

In the process of planting the last pin, pins FRB-01 and FRB-02 corresponding to the positions drawn in the pin planting diagram are selected according to the relationship between the pin name and the drawn shape in the correspondence table shown in FIG.
The insertion hole button provided in the base material of the inspection jig 11 is planted to obtain the inspection jig 11.

[Problem that the invention seeks to solve]

When manufacturing an inspection jig using the pin-planting diagram data created using the above-mentioned conventional apparatus, there are the following problems.

Mark If you specify a drawing shape that differs from the corresponding drawing in the process of drawing pin data, there is a possibility that the pins will be misprinted in the process of planting the pins.

(b) In the process of planting pins, it is inefficient to work while comparing the pin planting diagram with the corresponding diagram.

There is a problem.

In contrast to the conventional apparatus described above, the present invention has an original content in that it outputs pin planting diagram data that includes a correspondence table between pin names and drawn shapes as data.

[Means for solving problems]

An object of the present invention is to provide a pin installation diagram data creation device for a wiring inspection jig that creates such conventional pin installation diagram data for an inspection jig for a printed wiring board.

That is, according to the present invention, there is a data input section for inputting position data of through holes and pads of a printed wiring board and attribute data of each position data, and a data input section connected to the data input section to input each position data inputted through the data input section. A data storage unit that stores data, and a pin installation diagram that is connected to the data storage unit, creates pin installation diagram data from the position data and attribute data stored in the data storage unit, and stores the pin installation diagram data in the data storage unit again. A pin planting diagram data creation device for a wiring inspection jig is obtained, which has a data storage section and a data output section that is connected to the data storage section and outputs pin planting data stored in the data storage section.
