Halt & Hass Chamber

MEL Systems and Services offer the HALT and HASS Chamber. HALT – Highly Accelerated Life Test – is a process used during the design stage of a product that provides a stringent environment to force design and process maturity. HASS – Highly Accelerated Stress Screen – is a process used in manufacturing, to allow discovery of process changes and prevent products with latent defects from getting into the field. The Typhoon's Omni-AxialTM six degree of freedom, random, broadband excitation (10 Hz to above 5,000Hz) delivers a consistent power spectral density profile that eliminates picket fencing. The thermal system features vacuum jacketed liquid nitrogen injection cooling, open element nichrome heating, and offers temperature ranges of +200°C to -100°C with ramp rates of 60?C per minute. The Typhoon comes equipped with Qualmark's powerful custom control system designed for both lab and production environments. The chamber is available in various models.

Benefits of HALT:

• Quickly discover design and process flaws
• Evaluate and improve design margins
• Reduce development time and cost
• Eliminate design and process problems before release to manufacturing
• Ship a mature product at market introduction -  no ongoing field issues
• Use as a sustaining engineering tool to evaluate impact of product modifications and cost reductions
