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.
