Abstract: A first inspection functionality is provided to obtain information about a first attribute at a conductor location on an electrical circuit. A second inspection functionality is provided to obtain information about a second attribute at the conductor location. A combination of first attribute information and second attribute information is analyzed to determine an inspection attribute of the conductor at the conductor location. Attribute information may relate to one or more of: reflectance, fluorescence or height.

Abstract: Surface dimension and footprint dimension values are determined by scanning a printed circuit board with a laser. Exposed substrate parts of the printed circuit board fluoresce significantly, emitting detectable luminance, while conductors do not. Conductors reflect the laser light much more strongly than the exposed substrate, especially at the substantially flat part of the top surface. Luminescence and reflectivity collectors provide signals indicative of the footprint and surface dimensions. This cross-sectional information is used in making adjustment determinations in the manufacturing process, and also decisions relating to repair or discard operations.
