  • X-ray laminography system having a pitch, roll and Z-motion positioning system
    Patent number: 6977985
    Abstract: An x-ray laminography imaging system and a positioning system to be used therewith. The positioning system is configured to move the object in the X, Y and Z-directions (i.e., pitch and roll) to ensure that the object planes of the object that are being imaged are at least substantially parallel to the focal plane of the imaging system. The object is positioned so that object planes associated with the X, Y and Z-coordinates of points along the contour of the surface of the object are at least substantially parallel to the focal plane of the imaging system during imaging of the object plane. Because some objects, such as printed circuit boards, for example, are sometimes warped, by ensuring that the object plane being imaged is at least substantially parallel to the focal plane of the imaging system, precise laminographs are obtained.
