  • Patent number: 11176635
    Abstract: A system for measuring solder paste stencil aperture positions and sizes is provided. The system includes at least one camera configured to acquire images of the stencil and an alignment target. A motion system generates relative motion between the at least one camera and the stencil. A controller is coupled to and controls the motion system. The controller is configured to analyze the images to generate aperture information relative to the stencil. The aperture information is provided to automatically program a solder paste inspection system. Other features and benefits that characterize embodiments of the present invention will be apparent upon reading the following detailed description and review of the associated drawings.
