2D or 3D? benefits of combining both in a single X-ray system

Optimum flexibility in X-ray inspection is achieved by combining 2D real-time imaging with 3D Axial Computed Tomography (ACT) in a single system. Switching from one mode to the other takes only a keystroke; and the selection can be made anytime - and as often as required - during the inspection process. The role played by X-ray systems in the inspection of electronic assemblies - especially today\´s printed circuit boards, densely packed with area array components - is well understood. Unlike machine vision and optical inspection equipment, X-ray systems penetrate materials to expose hidden solder joints on area array devices, such as flip chips and BGAs. Once a need for X-ray inspection equipment has been determined, the next question is "which is best for the application, two dimensional (2D) or three dimensional (3D)?".
