Search for an area of interest in a frame for printed circuit boards quality control

Abstract

The method for searching an area of interest in a frame to control the quality of printed circuit boards has been considered. The control stages during the board testing by the non-destructive thermal method have been reviewed. The methods for obtaining contours of elements have been described, and the results of these methods are presented. The results of the experimental testing of the four boards simultaneously which have been obtained in the software created on the basis of the developed method are demonstrated. The developed method allows automating the process of searching an area of interest.
