Wear Mechanism Sand

Topic: Electronic/Electrical Reliability

While there are debatably some wear out mechanisms such as electromigration and component parameter drift, electronic systems behave fundamentally different than mechanical ones. Typical to a discussion of reliability is the concept of the bathtub curve.
