Abstract
A system for inspecting potentially warped printed circuit board assemblies is disclosed. The system includes an inspection head with an axial, centrally located camera, and a laser disposed at an angle off the central axis. The central camera and the angled laser can be used during an initial scan of a printed circuit board assembly to measure and compensate for warp in the assembly, thereby making a subsequent inspection of the assembly more accurate.
