Abstract:
1. An x-ray inspection system for producing images of a device under inspection, the system comprising; an x-ray tube having a rotating anode; a source of an electron beam directed at the anode; and a deflector for moving the electron beam in relation to the anode so as to shift the beam from a first region on said anode to at least one further region thereof, to cause the emission of x-radiation from said first and further regions at different times, the x-ray tube being located at an inspection station for said device and disposed to irradiate a first part of said device with x-radiation emitted from said first region of the anode and to irradiate a further part of said device with x-radiation emitted from said at least one further region of said anode; and a detector comprising an x-ray visualization surface for detecting x-radiation emergent from said device, wherein the x-ray visualization surface, the device and the x-ray tube are held in fixed relative spatial relation during inspection.
