Interfacial Fracture
Interfacial Fracture Next To Void
A useful comparison image because it shows an interface becoming the fracture path next to a large solder void rather than in isolation.
Interpretation
Why this image matters
This image is valuable because it helps explain why voids should not be treated as a simple percentage problem. The large nearby void changes the local geometry and helps explain why the interface becomes the preferred fracture path.
The report treated the local condition as interfacial fracture possibly associated with a large solder void and noted that voids and hard intermetallic particles likely contributed to local stress amplification.
It is a strong comparison image when you want to separate general interface fracture from interface fracture that is shaped by neighboring void morphology.

Best comparison value
- Teaching how nearby voids can change fracture interpretation
- Comparing interface-following fracture to pad cratering or laminate damage
- Discussing local geometry and stress concentration at a fracture site
