Unlike the typical equipment manufacturer’s HALT and HASS seminar that simply expounds success stories and testimonials, this course actually teaches the latest techniques. Taught by the inventor of HALT and HASS, we begin with the science behind why it works, provide the hard engineering and physics, and explain why the failures accelerated through higher stress levels are essential to developing reliable products. The course offers step-by-step instruction on why, how, and when to perform HALT, how to correctly set-up and tune HASS profiles on production units, and how to prove that the HASS profiles leave enough life left, so the products can be confidently sold to customers.
You will learn how to vastly improve design margins and eliminate process problems using the highly accelerated techniques taught by their originator. Emphasis is placed on environmental and other stress stimulation methods applied in the design phase in order to force accelerated design and process maturity using HALT. This allows earlier product introduction and obtains very robust design margins, leading to greater field reliability. Emphasis is also given to the application of HASS during the production phase to insure process and design control.
The second day of the class provides greater depth in stimulation, precipitation and detection methods and covers advanced HASS optimization and methods for doing production HASS on high volume products on a sample basis. Information is also provided that can help engineers “SELL” the program to upper management. Case studies are presented as learning experiences on how to perform HALT and HASS correctly; and sufficient time is spent discussing customized approaches for product samples brought to the seminar by attendees.
The Workshop takes place on the afternoon of day 2. In this advanced hands-on workshop, the participants learn techniques and methods that allow them to further refine and improve their existing methodologies. Upon completion, participants should be able to use these techniques without any additional assistance. Many of the subtle details required for successful use of the techniques are presented in this seminar and are not published elsewhere. During the workshop, a HyperHALT is performed by the attendees on a commercial electronic product using six axis vibration and high rate temperature cycling equipment. This session is hands-on with participant involvement in running of the tests and in the operation of the equipment used for stressing.
The majority of attendees leave the seminar equipped with the ability to implement their own HALT and HASS programs. Individualized remote and onsite consulting and equipment set-up/troubleshooting are also available.
The techniques are continually being refined "with advancements such as HyperHALT, which was introduced in 2007. We offer this updated course at a 50% discount to previous attendees.
SEMINAR OBJECTIVE
These classes equip participants with detailed technical knowledge of HALT (Highly Accelerated Life Tests) and HASS (Highly Accelerated Stress Screens). This will enable you to successfully initiate world-class highly accelerated design margin enhancement programs and highly accelerated production stress screen programs. Many of the subtle details required for successful use of the techniques are presented only in this seminar and are not published elsewhere. A recent addition is Rapid HALT, which is available free to previous seminar attendees in the form or a short paper.
CONTENT
This seminar will cover the latest methods for finding weak links in designs and processes that cause field failures in products. Emphasis is placed on environmental and electrical stimulation applied in the design phase (HALT) in order to force accelerated design and process maturity. This technique allows earlier (mature) product introduction and obtains robust design margins. Emphasis is also given to the use of the methods in the production phase (HASS) to assure process and design control. Either application results in cost savings and reliability improvements that are orders of magnitude better than those attained using the traditional approaches. Many leaders in reliability throughout the world are using the methods. Every aspect of the HALT & HASS processes is covered, including step stress testing, burn-in, voltage cycling, vibration, thermal cycling, other stresses as appropriate and cumulative fatigue damage as well as screens for parts, assemblies and systems. Physics of failure, test coverage and resolution, equipment required and management issues will also be discussed. The extreme non-linearities found in vibration of electronics and fixturing for both vibration and thermal cycling are covered. Several case studies are discussed and critiqued in class.
Most of the leaders in the application of accelerated screening technology learned from these seminars. The majority of them are not publishing complete results in order to maintain their technological and financial lead! Many do not publish at all!
WHO SHOULD ATTEND
The HALT & HASS Seminar is appropriate for managers, executive officers, design engineers, quality & reliability engineers, and production staff involved in Highly Accelerated Stress Screening including failure analysis. The HALT & HASS Hands-on Lab is appropriate for any staff involved in actually performing or evaluating the HALT & HASS activities. Some high level managers will want to attend only the first few hours which is a Management Overview.
