August 7, 2019 @ 8:30 am – 10:30 am


By Aldo Fucinari


Over many years of conducting seminars in HALT and HASS, some of the same questions come up time and time again. These questions are also posed when people are just starting to consider the benefits of product ruggedization using the HALT discovery technique. In this webinar Mr. Fucinari encapsulates lessons learned from Dr. Gregg Hobbs and Chet Haibel as well as his own 15 years of HALT and HASS testing and consulting. No matter what type or category of product that you have these principles will apply.

-I don’t like going beyond the product’s specs or the components’ specs. Isn’t that wrong?
-Once my product design is Ruggedized using HALT, why do I ever need to run HASS?
-Isn’t HALT vibration really just shock, not vibration? How are Gs of swept sine related?
-How can I use HALT To Predict the Life of My Product?
-Our products are already shipping, won’t I need to wait for the next generation product development to do HALT?
-One part of my HALT vibration table reads at a different Grms level than another part. Shouldn’t they be exactly the same?
-I already have fixtures designed and in use for my ED shaker testing. Why can’t I use them for HALT?
-I don’t feel comfortable running HASS, doesn’t HASS remove life from my product?
-Can I use my HALT fixtures for HASS?
-What stress levels do I start with to design a HASS test profile?
