Computerized Tomography
Dage’s computerized tomography (CT) option for digital X-ray inspection systems uses a digital geometric process to generate a 3-D image model from a series of individual 2-D X-ray image “slices” taken around a single axis of rotation. The captured images are fed in real-time to a dedicated reconstruction server that creates a 3-D image. Developed for analytical inspection of interconnections for stacked die, MEMS, package-in-package (PiP), package-on-package (PoP), and other dense applications, the CT option enables efficient conversions between 2- and 3-D modes for different inspection purposes.
