Gas Analysis & Leak Testing Webinar

Residual Gas Analysis (RGA), also referred to as internal vapor analysis (IVA), is a technique used to test the internal gas composition of an electronic device with an emphasis on moisture content. An electronic device, such as a semiconductor, microelectronic, heart pacemaker, or cochlear implant can be fixtured to the RGA instrument. This testing technique is a gold standard of reliability testing for military and aerospace industries following MIL-STD 883 TM 1018. There are only 2 companies in the United States that are certified by the US Defense Logistics Agency to perform this test.

Evolved Gas Analysis (EGA) is a method for monitoring small amounts of gas molecules evolved from samples when heated above room temperature. This analysis can be primarily used to determine: (1) the composition of evolved gases (2) the concentration of evolved gases (3) or the evolution profile with respect to heating temperature. This information is vital for quality control, failure analysis, or establishing a protocol for a manufacturing process.

Cumulative Helium Leak Detection (CHLD) is the process that the Pernicka Model 700H Leak Detector uses to detect leaks in hermetic packages. CHLD is a single leak testing system for sealed devices that combines the GROSS Leak and FINE leak methods. This technique can also be applied to any hermetically sealed device which contains Nitrogen, Helium, Argon, Krypton, Xenon, etc., or any device that can be “bombed” with Helium.
