Accelerated Life Testing and ESS Design

This course covers the concepts of accelerated reliability testing for electronics, mechanical components, and structural elements using state-of-the-art techniques. Accelerated life testing techniques are critical in helping organizations achieve Time-to-Market goals and reduce the likelihood of design escapes with warranty costs. The class is recommended for Design or Reliability Engineers interested in learning the techniques and fully understanding the method.
