Learn about the aging and stability challenges for electric components due to temperature and time using quartz crystals, as well as applying the extrapolation method, aging equation, and Arrhenius equation. Even with a fixed input, electronic circuits are not perfectly stable; often drifting with time and … Zobacz więcej The resonant frequency of a crystal changes with time. Two main aging mechanisms in quartz crystals are mass transfer and stress relief. The resonant frequency changes when a small amount of mass is … Zobacz więcej Based on the above discussion, we can then use the following logarithmic function to describe the variations of the resonant frequency with … Zobacz więcej In physical chemistry, the Arrhenius equation is a formula that describes the temperature dependence of reaction rates. According to the Arrhenius equation, the dependence of the rate constant of a chemical … Zobacz więcej The logarithmic model given by Equation 1 only specifies the time dependence of the aging process. The general aging equation of a quartz crystal can be written as: Δff(i,T,t)=R1(i)×R2(T)×R3(t)Δff(i,T,t)=R1(i)×R2(T)×R3(t) … Zobacz więcej Witryna1 maj 1998 · Accelerated aging is the precise use of screens that allow you to know where you are in the product life cycle without over-designing. Accelerated aging reduces design time and time to market ...
