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 two hour webinar, which costs $200, 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.

  1. I dont like going beyond the products specs or the components Isnt that wrong?

In this first segment we will look at the economy of current methods vs. the economy and effectiveness of HALT. A probability of failure chart based on stress levels will be compared with expected field AFR for a product (annual failure rate).

  1. Once my product design is Ruggedized using HALT, why do I ever need to run HASS?

The instructor will reveal real world examples of manufacturing and supplier defects that can only be found during HASS testing.

  1. Isnt HALT vibration really just shock, not vibration? How are Gs of swept sine related?

Understanding the difference between vibration modes are key to the way HALT works. Random vibration and 6 degree of freedom vibration will be explained.

  1. How can I use HALT To Predict the Life of My Product?

This is probably the most frequently asked question of all. An example will be provided that explains this phenomenon in real terms. You will be provided with the instructors approach which has been proven in virtually every case where there is existing field AFR data.

  1. Our products are already shipping, wont I need to wait for the next generation product development to do HALT?

This is very common misunderstanding. It is actually extremely valuable to run HALT on an existing shipping product for a number of reasons.

  1. One part of my HALT vibration table reads at a different Grms level than another part. Shouldnt they be exactly the same?

Probably the 2nd most frequently asked question. The instructor will answer this question then proceed to an example of how to qualify the vibration levels on a multiple unit HASS fixture. We will also look at coupling losses and how to work with them.

  1. I already have fixtures designed and in use for my ED shaker testing. Why cant I use them for HALT?

The way HALT vibration is generated is very different from an ED shaker. The differences will be explained including instantaneous peak head room which is 10X in HALT compared with 3X with ED shakers.

  1. I dont feel comfortable running HASS, doesnt HASS remove life from my product?

All cycle fatigue will remove some fractional amount of life. However, HALT, when done properly, extends the expected life of the product.  Safety of screen insures that the product can be confidently shipped and still survive well past warranty.

  1. Can I use my HALT fixtures for HASS?

Depending on the product under test and how the HALT fixture is designed, HASS requires the maximum number of units are populated in the chamber at one time. Examples will show how to optimize a HASS fixture.

  1. What stress levels do I start with to design a HASS test profile?

We will look at different product classifications and how much stress is appropriate for our HASS test. The instructor will walk through 3 different product classifications and the correct “Depth of Screen” to apply to each.
