HALT&HASS (Highly Accelerated Life Testing & Highly Accelerated Stress Screening), commonly known as HALT testing: is a testing method used during the product design and production stages to identify product defects and design margins. HALT&HASS technology assists in achieving product maturity, ensuring that high reliability and high-quality products are delivered to the market quickly.
The purpose of HALT&HASS is to identify the operational limits of a product by applying high temperatures and vibration stresses, treating product failures or malfunctions as the main subjects of study. It is a reinforced concept experiment aimed at improving reliability through the discovery, study, and improvement of failures and malfunctions.
Initially, the success stories of HALT&HASS were based on understanding the original spirit and correct logical thinking; today, the five major testing steps of HALT&HASS are merely reference concepts. In many cases, it is necessary to assess the actual conditions of the samples under stress, and to conduct preliminary evaluations of the feasibility and effectiveness of the tests. The information produced in this process is a prerequisite for successfully implementing HALT&HASS testing, which requires corresponding measurement methods and systems to complete.
Perhaps you have doubts about the testing effects and principles of HALT&HASS applications, or you want to truly master the formulation methods of HALT testing standards, or you want to understand why products can withstand 100G without failing? Or perhaps you want to know the difference between a vibration table with protrusions and one without!
Many tasks in HALT&HASS utilize high-speed cameras, displacement tracking software, and measurement analysis systems to integrate abstract concepts through real measurements for true validation. This is actually a manifestation of the Virtual and Reality Integration Refinement Technology (VRTC), combining practice and truth to provide a comprehensive view of HALT&HASS applications, which is the expectation and demand of practitioners in the field. To master the transition of HALT&HASS applications from qualitative to quantitative reliability engineering, it is necessary to understand the truly integrated VRTC solutions available in the market: the French EikoSim DIC strain measurement system, the American HANSE Highly Accelerated Life Testing system, and the Taiwanese ED-HALT electromagnetic vibration system. |
