underfill
Not quite full
Underfill is when something isn't filled to capacity or to the expected level.
The term appears in manufacturing contexts where containers, packages, or molds receive less material than intended: The quality control team flagged several bottles for underfill.
In electronics, underfill refers to an epoxy material injected beneath microchips to strengthen the bond between chip and circuit board, protecting against thermal stress and mechanical damage.
