BLNKK's current understanding
Please check the details- Structure / bonding interface
- Underfill fillet at the die edge and adjacent structures
- Observation stage
- Geometry inspection before and after dispensing, flow, and cure
- Phenomenon to localize
- Overflow, fillet height, or contamination of neighboring components
- Engineering decision
- Use edge profiles and clearances to neighboring components to guide comparisons of dispense paths, volume, or flow-barrier geometry
- Sample evidence still required
- How are edge profiles aligned with neighboring-component heights, clearances, and the process's own adhesive keep-out areas?
Paths to assess first
Paths serve different purposes and can be combined01
Inspect edge profiles and neighboring-component interferenceAlign contamination using geometry from the same stage
First02
Compare dispense paths and actual material deliveryHold material state fixed when comparing placement and flow
First03
Jointly check flow barriers and under-die fillingRetain edge improvements and compatibility trade-offs

Sample suitability still needs confirmationAssess outer-edge surface-profile measurementsKLA · Can help answer: Published 3D surface and edge-profile capabilities can be assessed for visible materials and geometry.
→Assess capillary-underfill paths and material deliveryNordson Electronics Solutions · Can help answer: Published manufacturer dispensing capabilities can be considered with controls for actual delivery and material state.
→Joint review of dispensing and flow-barrier compatibilityBLNKK engineering review request (provider unconfirmed) · Can help answer: Compare paths, volumes, or flow barriers only when actual delivery, edge geometry, and under-die / neighboring-component compatibility controls are all available.
