摘要： An x-ray imaging system according to the present invention comprising a stepped scanning-beam x-ray source and a multi-detector array. The output of the multi-detector array is input to an image reconstruction engine which combines the outputs of the multiple detectors over selected steps of the x-ray beam to generate an x-ray image of the object. A collimating element, preferably in the form of a perforated grid containing an array of apertures, interposed between the x-ray source and an object to be x-rayed. A maneuverable positioner incorporating an x-ray sensitive marker allowing the determination of the precise position coordinates of the maneuverable positioner.

摘要： A method and apparatus for optimizing the drilling position of a multi-layer printed circuit board prior to drilling. A template having precisely located target holes and fixture reference marks provides initial coordinate reference information for multi-layer printed circuit boards to be inspected by x radiation. Each board is processed by insertion into a holding fixture, examination of four quadrant target areas using x-ray sources and detectors, digitization of the target area images in each quadrant, and computaton of the optimum board position in a follow-on drilling apparatus. After optimization, three reference holes are punched along one edge of the board to provide accurate fiducial positioning marks when the board is placed in the drilling apparatus.
