Physics-of-failure models are often presented as the ultimate solution for predicting reliability—but are they always necessary? In this episode, Chris and Fred explore a listener's question about finding reliable references for physics-of-failure models, particularly for electronics and PCB assemblies. The discussion highlights the spectrum of available models, from simple empirical equations to highly detailed simulations requiring extensive material and manufacturing data. More importantly, they explain why engineers should start by defining the decision they need to make before searching for increasingly sophisticated models. If you're trying to improve reliability, select materials, design accelerated tests, or understand failure mechanisms, this episode offers practical guidance on when physics-of-failure modeling adds value and when simpler approaches may be more effective.
