BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring inspection data management system, and more particularly to a wiring inspection data management system using a network system.

[0002]

2. Description of the Related Art A conventional wiring inspection data management system includes:
For example, as shown in FIG. 5, which is a functional block diagram of a conventional wiring inspection data management system, a CAD data storage means 2 for storing CAD data, and an inspection process arrival input for inputting that a printed circuit board has arrived at the inspection process. Report input means 7
Read out the CAD data of the printed circuit board inputted by the empty wiring inspection device input means 8 for inputting the currently empty wiring inspection apparatus and the inspection process arrival report input means 7 from the CAD data storage means 2; Conversion means 5 for converting CAD data into inspection data for the wiring inspection device input by the inspection device input means 8 and inspection data notifying means 6 for notifying the inspection data converted by the conversion means 5 to the wiring inspection device. Has become.

When the printed circuit board arrives at the inspection step, an operator notifies the wiring inspection data management system by the inspection step arrival report input means 7. When the vacant wiring inspection device is notified by the vacant wiring inspection device input means 8 when the wiring inspection device is vacant, an inspection process arrival report is output from the CAD data stored in the CAD data storage means 2. The conversion means 5 reads the CAD data of the printed circuit board input by the input means 7 and performs data conversion for the wiring inspection apparatus. Then, the inspection data notifying means 6 notifies the selected wiring inspection apparatus of the inspection data.

[0004]

Generally, wiring inspection data is created by placing a substrate to be inspected on a wiring inspection apparatus and performing data downloading. However, if this method has a defect in the inspection jig attached to the device,
Because it is not possible to capture the inspection data for that part,
A completely correct inspection cannot be performed.

[0005] Therefore, a method of creating wiring inspection data from CAD data which is original data for creating a printed circuit board will be considered. In this case, it is necessary to extract points to be inspected from the CAD data and perform data conversion so that the points can be used in the wiring inspection apparatus. This data conversion
If the type of the wiring inspection device or the jig used is different, it is necessary to perform a different conversion. For this reason, it is necessary to input in advance which wiring inspection apparatus is to be converted.

In the conventional wiring inspection data management system described above, the data conversion cannot be performed until the printed circuit board to be inspected arrives at the inspection step and the wiring inspection apparatus is empty. It takes longer to enter

According to the present invention, there is provided a wiring inspection data management system comprising: a pre-process completion reporting unit for notifying that a pre-process of a wiring inspection process has been completed;
CAD data storage means for storing D data, inspection status inquiry means for inquiring the inspection status of the wiring inspection device, and wiring inspection device which is likely to end the inspection from the inspection status of the wiring inspection device inquired by the inspection status inquiry device The CAD data of the substrate reported by the pre-process completion reporting means is read from the CAD data storage means, and the inspection situation determining means determines that the inspection is about to be completed. It is composed of a conversion means for converting CAD data into inspection data, and an inspection data notifying means for notifying the wiring inspection device of the inspection data converted by the conversion means.
