WebPreconditioning and Reliability Preconditioning is a simulation of the surface mount process that is typically done at the PCB assembly houses. At Na-tional Semiconductor preconditioning is done prior to the fol-lowing reliability tests: temperature-humidity bias, autoclave, and temperature cycle. The preconditioning flow that is used WebThis stress is performed prior to package reliability qualification tests (HAST / THB, TC, UHAST). Variables: Bake = 125°C / Moisture Soak = 30°C / 60%RH / Reflow Temperature = 260°C. Other conditions may be used. 3.
