Helium bombing is part of the leak test process for hermetically sealed components which have an internal cavity like transistors, diodes or small relays. These parts are placed in a chamber containing pressurized helium, allowing the helium to penetrate the parts. The part is then tested in a vacuum chamber connected to the leak detector. Important considerations include pressurization time, helium bombing pressure, internal volume and leak size.

Clamps are controlled by high air pressure amplified by pressure booster
Locking mechanism of the chamber by 3 sets of pneumatic clamps
Optical sensors ensure safety of work when open/close the chamber
