IPC-9701 defines thermal cycling test methods for evaluating solder joint reliability. Superb uses IPC-9701 as the reference for thermal stress testing — -40°C to +125°C cycling, in-situ electrical monitoring, and post-cycle failure analysis.
A board that passes ICT and FCT on the bench at 25°C still has to survive the real world — -40°C cold starts, +85°C engine compartments, salt fog at sea, and years of thermal cycling. This article covers the four pillars of environmental testing: tem
