This category presents anonymized failure analysis case studies based on real-world investigations. Each article outlines observed failure symptoms, analytical techniques applied, and engineering reasoning used to isolate root causes. Case studies are intended to demonstrate practical failure analysis workflows and evidence-based interpretation rather than promote specific products or solutions.
Counterfeit electronic components remain a persistent risk in modern supply chains, particularly when parts are sourced outside authorized distribution channels. This case study describes how a suspect lot of integrated circuits (ICs) was evaluated to determine authenticity and risk before entering production. The objective was not only to identify whether the parts were counterfeit, but …
Light-emitting diode (LED) discoloration is a common field concern in electronic assemblies, particularly in applications involving elevated temperature, humidity exposure, or long operating lifetimes. While discoloration is often perceived as a cosmetic issue, it can be indicative of underlying material degradation mechanisms that may ultimately impact optical performance or device reliability. This case study documents …
