... and testing. These characteristics have made X-ray inspection systems a critical non-destructive imaging and analysis tool in the failure analysis laboratories. Most of the commercial X-ray equipment are projection based systems that place the sample in the X-ray beam path, emitted from micro-focus or nano...
