What you will learn: 

This course covers the environmental and reliability tests performed during design and in manufacturing. You will learn about reliability prediction techniques and factors. You will learn what you can expect from reliability growth testing environmental stress screening (ESS). You will know how environmental stress screening (ESS) is used to flush out flaws introduced during processing, fabrication and assembly. When highly accelerated for longer duration, this is called Reliability Test. You will learn how Reliability Test can flush out design flaws resulting from incompatible interfaces, from erroneous functional performance in different environments and from weak components. By the completion of this course you will be able to formulate environmental and reliability test strategies for your own products.

Who should Attend: 

This course is for test and reliability engineers interested in uncovering both design and manufacturing flaws through environmental stresses.
