Development of axial laminographic system for electronic packaging inspection

Abstract

X-ray laminographic image can provide more useful information about the internal state of electronic packaging than x-ray radiographic image does. Many kinds of laminographic system have been developed for obtaining the cross-sectional image. Proposes an axial laminographic system, which can be constructed by usual automatic radiographic system without any rotating x-ray head and detector system. Explains that this method can be implemented to make the usual radiographic x-ray inspection system equal to the power of a laminographic system.
