Packaging Voids
Die-Attach Void
A large void in the die-attach region that connects an internal gap to a later structural consequence rather than leaving it as an abstract observation.
Interpretation
Why this image matters
This is a strong packaging-void reference because the void is located in a mechanically important support region under the die, not in an incidental package area.
The report concluded that die cracking initiated at this large die-attach void and that thermal-mismatch stresses during operational temperature cycling likely drove the later fracture.
That makes the image useful for explaining when an internal void should be considered part of the root-cause chain rather than just a background condition.
