The Industrial Inspection System for Board Implementation VARIR, Developed by Sony

The purpose of VARIR is to guarantee the best quality for the production process. However, it is not only developed as a board inspection system but also as a core machine, which can fulfill various requirements. Sony EMCS Corporation Kohda TEC thus instructed their laboratory to select the most suitable image-processing engine for the development. Their summary says: "The reasons why we selected HALCON finally are as follows:

• HALCON has powerful development tools.
• HALCON can directly generate C++ source code based on the algorithms, which are developed and tested, without the need of further manual changes.
• Other peripherals functions than image processing are also packaged.
• When PC performance is improved in future, the system also can immediately take advantage from the higher performance without code modification.

As for the above item 3 especially, HALCON can support various functions like socket communication, RS232C, mouse control and so on, because it is dedicated for machine vision development system. The above features enabled us to reduce the development period dramatically. It is needless to say that HALCON provides complete image processing functions as main features of course."

VARIR allows to performs tests as soon as the data is created. Optimized parameters are stored internally as soon as they are determined so that they can be easily re-used again for the same inspected parts later on. In addition, VARIR supports function for re-extending libraries of stored parameters and for converting all of them at once under specific conditions. Selected parameters, which should be changed, can be converted at once by such functions. When finding defective parts, VARIR outputs the properly processed data so that operators can easily classify and rate the defects. In addition to the above-mentioned functions, the following are supported:

• Storing and sorting of previously found defects and rated results.
• Training function.
• Data editing function in off-line mode.
• Localized management of rating for defectiveness.
