High Accelerate Stress Test Chamber
HALT and HASS are unique reliability test methods for finding faults and weak spots in a product before they are discovered in the field. The HALT method is often used during the development phase of a product in order to quickly find any weak components at an early stage and so eventually realise a more robust product before it is put into production. The HAST method is applied after production in order to detect any defects that may have occurred before or during the production process.
Extreme thermal (temperature) and mechanical (vibration) stresses are applied to a product during a HALT or HASS test. Because the chambers are connected to nitrogen, temperatures of -100 °C tot +250 °C can be achieved and temperature changes of 100 °C can even take place. In combination with different vibration levels, this creates great stress on a product.
