BLNKK's current understanding
Please check the details- Structure / bonding interface
- Solder / conductive-adhesive bondline beneath the die
- Observation stage
- Initial attachment and after curing / reflow
- Phenomenon to localize
- Bondline voids or incomplete coverage
- Engineering decision
- Use initial defect locations and attachment-process data to plan comparisons of dispensing, degassing, or the attachment window.
- Sample evidence still required
- How are pre-cycling gaps correlated with the material beneath the die and normal regions?
Paths to assess first
Paths serve different purposes and can be combined01
Initial coverage localizationReview initial gap locations and imaging limitations.
First02
Actual material delivery and attachment historyHold the material constant when comparing delivery and actual attachment histories.
First03
Surface and geometry comparisonsHold surface, gap, and support conditions constant or vary them separately. Do not determine acceptance from average void fraction.

Sample suitability still needs confirmationSolder delivery and reflow-outgassing comparisonIndium Corporation · Can help answer: Public die-attach solder documentation supports comparing actual delivery, flux, and reflow histories. First ask what data and candidate materials are available for this solder / geometry.
→Method review for initial coverage localizationBLNKK engineering research summary · Can help answer: Review initial gap locations and imaging limitations.
→Material-delivery / attachment or surface-geometry comparisonBLNKK engineering research summary · Can help answer: When inputs are complete for either actual material delivery and attachment history or surface and geometry comparisons, prepare that independent comparison first. The other retains its unconfirmed / excluded status.
