Description
Thermal Vacuum (TVAC) chambers are used by space component manufacturers to test
components, sub-systems and even entire satellites under space-like conditions. It is
essential that the T&M components, including cable assemblies, used to test the deviceunder-test (DUT) inside the chamber be specifically designed to accommodate the
effects of pressure and temperature created within the TVAC chamber.
Outgassing is the process whereby varying temperature and vacuum conditions
cause materials to release free volatiles, which can deposit on other components in a
test system and cause significant contamination. StabilityTVAC™ assemblies use low
outgassing materials which meet the requirements of ASTM E-595 with a TML less than 1% and
CVCM less than 0.1%
Changes in vacuum conditions force air in and out of cable assemblies, which can cause
damage if not properly accounted for. Standard connectors require a slower change
in pressure or risk damage. StabilityTVAC™ uses vented connectors which allow air to
escape much faster, thereby empowering cable assemblies to stabilize and be used with
minimal delays, and tests to be performed using rapid pressurization/depressurization
cycles.
Like most mechanical components, cable assemblies expand and contract when
presented with varying temperatures, which can cause changes in performance
and even a permanent degradation. StabilityTVAC™ cable assemblies are thermally
conditioned, going through aging and stabilization to relieve mechanical stresses for
reliable performance over temperature.
