PHYSICS OF FAILURE Training Course

This course offers an introductory understanding of some of the key engineering accelerated test techniques needed to develop reliable electronic products.

About this course.

Participants are presented with various physics of failure methods to provide design and test for reliability, and they will . . .
• Learn how products really fail and understand key reliability issues.
• Become acquainted with the failure modes and mechanisms associated with various electronic devices and assemblies.
• Determine the stresses associated with the assessment of reliable electronic equipment and examine techniques to address problems of reliability.
• Investigate the usage and applicability of reliability standards and handbooks.
The content of this course is complementary to the HALT and HASS seminars.
