New HALT/HASS chamber from Vötsch Industrietechnik.
HALT is a step stress process performed during the product’s prototype phase that de-termines a product’s operating limits, identifies design weaknesses, and identifies weak components. The prototype phase is the fastest and least expensive point to make improvements. In the HALT process, the test sample is subjected to progressively higher stress levels. Thermal dwells, rapid temperature transitions, vibration, and a combination of temperature and vibration are employed to precipitate latent, inherent defects in the design, at the component level, or in the manufacturing process. HASS is a post-production process that can be performed on 100 % of product or a partial sample of units. The main goal of HASS is to precipitate and detect hidden or latent failures. It is used to verify that no new “weak link” has crept into the product, since HALT, that has shifted the limits found in HALT. The Star Galaxy™ HALT/HASS Systems are integrated Test Chamber/Vibration Table packages.
The Star Galaxy chambers are equipped with a Liquid Nitrogen (LN2) cooling system, which provides the rapid thermal change rates (up to 70 K/min.) required to achieve maximum product stress. The Galaxy system efficiently delivers high velocity conditioned air to the test space for unmatched temperature cycling performance. Our adjustable air flow package allows the user to redirect and concentrate airflow to the product under test for maximum product temperature cycling stress. Galaxy system rapid thermal change rates are accomplished with smaller space requirements, lower audible noise, no water requirement, lower maintenance costs and greater efficiency than a typical refrigeration system.
The vibration table is a state-of-the-art, six degree-of-freedom (6DoF) triaxial pneumatic vibration table. A benefit of its patented unique proprietary construction, this vibration table has one of the most consistent acceleration levels per unit area of any table presently on the market.
