Complimentary inspection techniques
The 3-dimensional information acquired in X-scans permits the tomographic reconstruction of the system’s internal structure.
Alter TECHNOLOGY is specialized in applying X-Ray Inspection (2D and 3D tomography) 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 Scanning Acoustic Microscopy (CSAM).
The purpose of a Radiographic Inspection is to nondestructively detect defects that are not otherwise visible: improper positioning of parts, broken elements, inhomogeneities in materials, foreign objects…
In particular, and for microelectronics samples helps us 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.
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 in Alter Technology in EEE testing and engineering.

Virtual Labs conducts your tests, organizes your data into a smart database using Predictive Analysis. Real-time control, lowest price, comparative analysis.
Thanks to the Virtual Lab tool, the customer can devise his own test solution specifically adapted to the actual needs and requirements and monitor test results in real-time, without the need to wait to complete all the activities. Therefore, the final user can adapt the inspection areas and planes depending on the initial results. He will also receive feedback and advice from our test engineers during or thereupon inspection.
Detailed inspection records can be accessed immediately after the activity completion. Thus, manufacturers and users gain valuable time to develop contingency plans and solutions to address detected anomalies.
