Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data conversion device and a data conversion method, and more particularly to a data conversion device and a data conversion method for generating inspection data from data of any different format.

[0002]

2. Description of the Related Art In recent years, CAD (Computer AI) used at the time of design in an inspection in a manufacturing process of electric equipment or the like has been used.
Increasingly, data for inspection is created using data (ded design) and mounter data.

[0003] In particular, in the appearance inspection of a mounting board, CA
Since inspection data can be easily created by creating inspection data using D data or mounter data, creation of inspection data using CAD data or mounter data has become widespread. FIG. 4 shows a conventional process of creating inspection data.

[0004] CAD systems are sold by various manufacturers, and in many cases, data for manufacturing can be created from data for design. However, in general, the C
AD data is not compatible. Therefore, in order to create the inspection data, the CAD data 210 of the maker A is converted to the inspection data by performing the automatic conversion A using the data conversion device A (510). Similarly, the CAD data 220 of the maker B is converted into inspection data by the data conversion device B (520), and the CAD data 230 of the maker N is converted into inspection data by the data conversion device N (530).
The inspection data generated by each data conversion device is collectively recorded on a recording medium and used by the inspection machine 400.
In the same manner, the inspection data is created for the mounter data by a data converter dedicated to the mount data.

In general, CAD data and mounter data have no regularity, and even if they are of the same manufacturer, there are data of the same format but different data meanings depending on the user who uses the data. Therefore, it is difficult to share them.

[0007] From such a background, it is difficult to avoid diversification of the format of CAD data and mounter data. As a result, as many data converters as the number of formats are required, and a suitable data converter must be prepared each time. This not only complicates the procedure for creating inspection data, but also makes the data conversion system expensive.
