The purpose of a Radiographic Inspection is to nondestructively detect defects which are not otherwise visible: improper positioning of parts, broken elements, inhomogeneities in materials, foreign objects… In particular, and for microelectronics samples helps us get a better look at die attachments and wire bonding patterns or better identify die-attach voiding and inconsistencies in wire-bond integrity, either of which can play a significant role in decreasing product reliability. Alter is specialized in applying X-Ray Inspection to Failure Analysis, Destructive Physical Analysis, Constructional Analysis, Counterfeit Detection, Lot Screening or Process Development and Verification. X-Ray analysis often is used in conjunction with other investigative techniques, particularly CSAM.

This type of analysis involves a qualified and multidisciplinary team specialized in different disciplines such as Materials Science, Physics, Electronics, and Aerospace Engineering. This team is supported by more than 30 years of experience of Alter Technology in EEE testing and engineering.
