Abstract

The aim of the project is to develop a system for automatically inspecting the soldering of circuit boards. The system detects the quality of the soldering, determines if the board will work or not, and indicates the position of any incorrect soldering work. The system is based on the analysis of characteristics using a dedicated processor of 7 X 7 pixels. The method detects the quality of soldering work with a much quicker processing time than using conventional image treatment. The paper will describe the above mentioned system, the layout of the installation and the architecture of the board used as well as the algorithms implemented and the results obtained. The presentation will cover all areas of the project and will prove useful to those interested in automatic visual inspection techniques.
