X-ray tomography is a promising technique that can provide micron level, internal structure, and three dimensional (3D) information of an integrated circuit (IC) component without the need for serial sectioning or decapsulation. This is especially useful for counterfeit IC detection as demonstrated by recent work. Although the components remain physically intact during tomography, the effect of radiation on the electrical functionality is not yet fully investigated. In this paper we analyze the impact of X-ray tomography on the reliability of ICs with different fabrication technologies.

Hi all. I have put.an ic on the y wagon and done first.and last component. The machime picked up the part while testing the package but it didnt center the part ,just sat there for a while and failed. Any idea why this is and am I missing something?

On some of the older models you cannot have all of the other accelerations turned up and theta set to slow. Bump up the theta speed.

For upside down and rotated parts try using the index mark (F6) in the package database for that component, at least then the machine should look for a unique feature on the bottom and if it cannot find it the part will be rejected. For the index ma
