High-temperature Aging Method to Evaluate Electronic …
WebThe general aging equation of a quartz crystal can be written as: Δf f (i,T,t) = R1(i) ×R2(T)×R3(t) Δ f f ( i, T, t) = R 1 ( i) × R 2 ( T) × R 3 ( t) Equation 2. Where R 1 (i), R 2 (T), and R 3 (t), respectively, take into account the dependence on drive level, temperature, and time.
