Solder Voids
Large Interface-Adjacent Void
A solder-void comparison image where the void is both very large and directly adjacent to the interface rather than sitting harmlessly in bulk solder.
Interpretation
Why this image matters
The void sits where it may change local support and stress distribution rather than simply occupying an interior bulk region.
It is a good example of why some voids deserve more attention than others even before a full failure sequence is reconstructed.
The value here is practical judgment: size matters, but size plus location matters much more.

Best comparison value
- Comparing large interface-adjacent voids to less critical bulk porosity
- Teaching why local support loss changes void significance
- Discussing effective joint area and stress concentration
