Helium Leak Testers are used to measure fine leaks.
Helium is utilized as the test medium along with a detector to sense any presence of the gas. Presence of the gas in a known concentration equates to a leak value.
A concentration of helium is typically filled in the cavity of the Device Under Test (DUT). The amount of helium which escapes through the DUT is sensed by means of a helium detector.
The following techniques are deployed for cycle time improvement:
Dual stage vacuum to evacuate the Device Under Test and the test chamber prior to filling with Helium resulting in improved cycle times.
Measurement of pressure differential between the helium pressurized Device Under Test and the test chamber under vacuum
