Creative Electron ©2019 Creative Electron, Inc. What is the impact in the inspection needs? n X-ray machines needed to inspect bottom terminated components n Higher magnification needed to resolve smaller features n CT inspection needed for some 3D architectures Creative Electron ©2019 Creative Electron, Inc. CT Inspection n A 3D Non Destructive Testing control n Tomography consists first in the acquisition of several radiographic projections of a given object n As a second step, from the acquired projections, tomography consists in processing a 3D homothetic clone of the object by the mean of a 3D reconstruction software
