HALT / HASS is the quickest and most economical way to improve product reliability.
HALT (Highly Accelerated Life Test) is used to discover design flaws by exposing the product to combined thermal, tri-axial vibration, voltage stresses and cycles.

HASS (Highly Accelerated Stress Screening) tests performed at the production stage employ environmental conditions similar to HALT. The test limits of HASS are frequently well beyond the qualification level, but not at the extreme stress levels conducted in HALT tests.

Hermon Laboratories team of professionals provide comprehensive services including test plan preparation, testing, root cause analysis, and support for product design & reliability improvement.

Hermon Laboratories uses the most advanced testing equipment featuring:

  • High temperature, low temperature, rapid temperature cycling combined with tri-axial vibration, software-controlled.
  • Large work size vibration table with 90% of vibration energy concentrated in the 5 – 4000 Hz low frequency range and applied equally to all axes. Tri-Axial vibrations, Six-Degree-of-Freedom (6DoF) with a non-coherent broadband spectrum of 5-10000 Hz at a level up to 100 gRMS.
  • Pneumatic actuators.
  • A closed loop cascade temperature control, based on measurement of air and product temperature, with an accuracy of ±10C (after maximum stabilization for 2 minutes).
  • FFT and Failure analysis
