Hobbs – Reliability Physics: How to Field Reliable Products

September 14, 2021 @ 8:30 am – 11:30 am


By Dr. Abhijit Dasgupta


This course offers an introductory understanding of some of the key engineering design principles and accelerated test techniques needed to develop reliable electronic products. Participants are presented with various reliability physics methods to design and test for reliability. 

Participants will…. 

• Learn how/why products really fail and understand key methods to make products sufficiently reliable

• Become acquainted with the degradation modes and mechanisms associated with various electronic devices and assemblies 

• Determine the stresses associated with the qualification of reliable electronic equipment and examine techniques to address reliability problems

• Investigate the usage and applicability of reliability standards and handbooks
