  • X-ray Radiography

X-ray Radiography is a nondestructive failure analysis technique used to examine the interior details of the package. X-ray inspection uses the fact that X-ray penetration varies according to the type of material and thickness. The device is subjected to penetrating X-rays and a resulting image is produced on a photographic film or on a screen (for real time X-ray). The recorded radiograph is a shadow image which shows the differences in density brought about by internal material variations in the device under observation. This method is effective for detecting interconnect defects, die attach voids, package voids and cracks inside the plastic sealed package
