HALT - Highly Accelerated Life Testing & HASS – Highly Accelerated Stress Screen
HALT/HASS testing is more of a process rather than a test. Rocky Mountain Testing Solutions offers HALT Testing (Highly Accelerated Life Testing) and HASS Testing (Highly Accelerated Stress Screen).
The HALT test process helps product designers to detect flaws in complex electronic products and manufacturing processes to create a more robust and reliable product, thus improving field reliability and reducing warranty cost. When successfully applied. HALT testing rapidly exposes
product weaknesses and gives the designer the opportunity to provide a more mature product at new product launch.
Vibration, thermal cycling, and power cycling are used to determine operating and destruct margins. Our environmental test chambers are available in sizes from reach-in to walk-in, ideal to match the size of your package or product. RMTS has all of lab simulation equipment required
to create these types of environmental conditions as well as for altitude, temperature, humidity, etc. Random vibration testing (include sine, random, sine on random, resonance search, and fixture evaluation) and temperature cycling have proven to be very successful forms of ESS.
WHY IMPLEMENT HALT/HASS TESTING
Effective HALT/HASS screening programs, which are applied during your product development and production phases, can yield significant test time savings, cost savings, and improvements in field reliability. Producing a quality product is about more than just looks and proper measurements. Knowing strengths and weaknesses can help products withstand the extremes and be used in multiple applications. Proper testing can also increase the strength and longevity of mechanisms. The maturity of your manufacturing process will determine how the screening test works, but an RMTS lab technician will assist you in choosing an environmental stress screening profile with several different methods available.
