What does ESS stand for?

The unit comes in two versions, Type 4526 and 4526-001, which are the best candidates for vibration measurements under continuous, high-temperature operation on gas-turbine auxiliary equipment, power train, engine and exhaust and environmental stress screening.

Board cleanliness must represent the amount of residues detected in critical areas that correlates to electrical performance in the field and environmental stress screening.

Environmental Stress Screening Guidelines for Assemblies, Institute of Environmental Sciences, 1990.

Several industry groups and companies conduct environmental stress screening and other tests on assemblies manufactured with lead-free processes.

The new facility provides an expanded environmental stress screening capacity, more efficient materials management and an enhanced ability for the company to readily respond to advancements in production technology.

The mil/aero market and recently the high-end commercial market have evolved test protocols-HALT, environmental stress screening (ESS), highly accelerated stress screening (HASS), databases, failure mode and effects analysis (FMEA) and models-to detect failure modes and weak links, to define failure rates of nominal and extreme products, to correlate failure modes and times with dimensional and other signature characteristics.
