Failure Analysis

Definition

Failure analysis is the process of investigating and determining the cause of a failure in a system or component. It aims to understand why a failure occurred, identify contributing factors, and provide insights to prevent future failures. In the context of electromagnetic systems, particularly those affected by electromagnetic pulses, failure analysis becomes crucial to safeguarding sensitive electronics from potential damage.
