Gross Leak

Gross leak is a term used in microelectronic package hermetic leak testing.  A hermetically sealed package is subjected to a bubble leak test by submerging the sealed package into a 125°C heated perfluoropolyether solution. Packages with visible bubbles exiting the package will be classified as a "gross leaker rejects."
