Abstract

One of the major parts of any vision system design is the development of effective illumination techniques. For high accuracy applications one can not afford to ignore an obvious source of error, namely a poor lighting system. In electronic manufacturing, accurate placement of fine pitch surface-mount components (SMCs) requires the integration of a vision system with the placement system. This paper describes the design of very effective lighting techniques for a vision-assisted system to place surface-mount components. The lighting systems provide consistent images of SMCs and pads with high contrast.
