X-Ray Tomographic Techniques for Inspection of Electronic Components

  • R. J. Kruse
  • R. H. Bossi


X-ray tomographic techniques including computed tomography (CT) and laminography (body scan tomography) have been examined for their potential for meeting the manufacturing inspection requirements of electronic components and printed wiring assemblies [1,2]. Comparisons with radioscopic inspections have been made.
