The Qualification Gap: Why Thermal Cycling Tests Pass in the Lab and Fail in the Field

Standard thermal cycling qualification profiles are built around industry averages—not the specific temperature extremes that automotive, aerospace, and industrial electronics encounter in real-world deployment. The result is a dangerous gap between a product that passes validation and one that survives in customer hands, and closing that gap requires rethinking how thermal stress is simulated from the earliest stages of PCB design.
