Research on the Sealing Detection Technology for No Leak Detection Interface Specimen

摘要

The sealing detection technology for no leak detection interface specimen was introduced, such as bubbles leak detection, back pressure leak detection, advance helium leak detection, fluorescence permeation leak detection and inside helium source leak detection, including their principles and specialties. The suitable object, advantages and disadvantages of those leak detection technologies were analyzed, which offered theory reference for doing correlative work.
