  • Method and apparatus for inspecting a solder joint using a correlation neural network
    Patent number: 6023663
    Abstract: A solder joint inspection process and system includes using a correlation values to classify the shape of the solder joint. The solder joint is illuminated by a multiple colors, and the image of the solder joint is captured. This multiple color image is then converted into a plurality of one-dimensional vectors. Each one-dimensional vectors sequence is for one color of the multi-color illumination and for a one-dimensional spatial extent. Correlation values among all combinations of the one-dimensional vector sequences are computed and used for training an automatic solder joint shape classifier.
