BLNKK's current understanding
Please check the details- Structure / bonding interface
- Solder intermetallic compounds and UBM / pad interfaces
- Observation stage
- Physical analysis after assembly, thermal aging, or mechanical loading
- Phenomenon to localize
- Brittle fracture surfaces along IMC / metal interfaces
- Engineering decision
- Use fracture location and metallization / aging history to guide interface-material and bonding-process comparisons
- Sample evidence still required
- Which layer contains the original crack, and could preparation shift the fracture surface?
Paths to assess first
Paths serve different purposes and can be combined01
IMC / metal fracture-surface and layer-sequence analysisAlign both fracture surfaces with normal interfaces
First02
Stage-by-stage metallization and aging comparisonsHold contact layer sequence fixed when comparing histories
First03
Controlled contact mechanics and fracture-surface comparisonsFix tool mode and failure classification
FirstCurrent candidate solutions
Sample suitability still needs confirmationAssess targeted IMC fracture-surface / layer-sequence analysisASE · Can help answer: Published SEM, EDX, and cross-section capabilities can be used to confirm phase-identification and preparation scope for a localized interface.
→Assess controlled shear / pull modesNordson Test & Inspection · Can help answer: Published bond-test capabilities can be assessed for a specific mode and the accessible contact region.
→Joint review of materials, aging, and mechanical fracture surfacesBLNKK engineering review request (provider unconfirmed) · Can help answer: Compare materials or bonding processes only when layer sequences, metallization and thermal histories, and fixed mechanical modes are all available.
