Multi-technique failure analysis and reliability verification for advanced packaging
MA-tek · Reliability qualification and failure analysis
- Purpose
- Delamination, cracks, voids or electrical changes after reflow, thermal cycling or service require defect localization before structural or material changes can be linked to the failure.
- Technical approach
- A case may combine X-ray/XCT and SAM/SAT localization with FIB cross-sections, SEM/TEM/STEM and EDS for local structure and composition. Reliability tests can support comparisons before and after exposure.
- Scope of use
- The published service covers package structures, internal defects, interfaces and material differences, including analysis around reflow or reliability testing. Accessible regions and methods for a particular advanced package require laboratory confirmation.
- Limitations and open questions
These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
Scope and limitationsA defect image or compositional difference may not establish root cause on its own. SAT penetration and detectability depend on the specimen; water coupling and destructive preparation need prior agreement.
What to prepareBLNKK suggests preparing the failure symptoms, package structure and suspected locations, moisture/reflow/cycling history, control samples and existing electrical or imaging results, plus acceptable preparation methods.
Confirm with the supplierConfirm analysis sequence, sample count/consumption, interface accessibility, test conditions and interpretation criteria, raw-data/report deliverables, and the laboratory performing the work.
- Public evidence
- The packaging service page lists non-destructive inspection, cross-section/material analysis and tests including TC, HAST and HTS. The SAT page explains acoustic inspection of delamination, voids and cracks; these document service scope.
