PREVENTING THERMAL CYCLING AND VIBRATION FAILURES IN ELECTRONIC EQUIPMENT

by Mr. Larry Edson, BSME, CQE

"Designing reliability into the product" is not just a catchy phrase, but an engineering process that is the most cost effective of all the reliability tools. This is 100% problem prevention. Designing reliability into electronics requires a deep understanding of the physics of "how things fail" along with mastery of the engineering methods to prevent these failures. Larry Edson will be teaching the two day class, "Preventing Thermal Cycling and Vibration Failures in Electronic Equipment," which specifically addresses the knowledge and design methods needed to "design in reliability." The book by Dave Steinberg with the same name as the class will be provided and used as reference. However, a complete set of notes containing worked examples will also be provided to bridge the gap between the text book and real life applications.

This is not a management overview class and students will be expected to bring their calculator and participate in solving real problems in class. "No student left behind" is the underlying foundation even though the class is of high technical content. The instructor, Larry Edson, is well known for being able to present in simple understandable terms the most complex aspects of Reliability Engineering.

Class Outline:

1)    This class focuses on the analytical portion of the Analysis-Qualitative-Quantitative strategy which is proving to be most effective in Reliability Engineering.

2)    How much design margin is needed to accomplish a required level of reliability?
a)    Design margins needed for mechanical or thermal fatigue situations.
b)    Derating - how much derating is needed to accomplish the reliability objective.

3)    Developing a deep understanding of the major sources of reliability failures in electronics.
a)    Vibration
b)    Mechanical Shock
c)    Thermal Fatigue
d)    Fretting Corrosion in Connectors

4)    Designing to prevent failures due to the failure mechanisms listed above.
a)    Detailed worked examples showing how to design reliability into the product for each of the failure mechanisms noted above will be provided in the class notes.
b)    Understanding Miner's Rule for combining thermal fatigue and vibration fatigue.
c)    Understanding the Octave Rule.
d)    Rule of thumb design principles that have proven effective for vibration.
e)    Accelerated test methods for all of the above.
