DPA wirebond fracture and construction analysis service

Integra Technologies · Reliability qualification and failure analysis

Purpose: Lifted wirebonds or heel cracks need original morphology and construction evidence.
Technical approach: An agreed DPA plan combines opening, microscopy/SEM, EDS and bond pull/shear testing.
Scope of use: For packages permitting destructive sampling; select methods for the package, lot and investigation.
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 limitations
Opening can alter evidence. Test-created fractures are not original fatigue surfaces; sampled DPA does not establish field life or automatically certify an entire lot.
What to prepare
BLNKK suggests preserving original images, wire/package construction and lot/stress histories, and agreeing which samples may be destroyed.
Confirm with the supplier
Confirm opening methods, available analyses, sampling and acceptance criteria, and how the report distinguishes original defects from preparation or test damage.
Public evidence: The service page lists delidding, SEM, EDS, bond pull and die shear; the February 2024 FAQ also lists sections and wirebond pull/shear.
