Delamination
Lens-to-Die Delamination
A clean package-interface separation example showing delamination at the edge of an LED die.
Interpretation
Why this image matters
The interface separation is visually clean, which makes the image easy to explain and useful for showing that delamination can be a functionally meaningful feature rather than an incidental preparation artifact.
The report tied the LED failures to both delamination of the lens from the die surface and one or more weak ball bonds that appeared sub-standard.
That combination makes this a good example of an interface feature that should be interpreted in the broader package-failure context.
