A deep dive into how and why Apple's post 2016 MacBook Pro's fail after water ingress, and the poor design decisions that lead to it. Which engineer at Apple is to blame? Or is anyone actually to blame?
The PCB and product design process, the often siloed design jobs, and failure mode analysis
Includes a demo of water hydrolysis on a PCB.
