Solder Refl ow Profi le Frequency vs. Temperature Characteristics
To calculate the frequency stability the parabolic curvature constant (K) is needed.
For calculating the stability at 45°C?
1- Change in temperature ( T) is (45-25) = +20°C
2- Change in frequency is (-0.034 x ( °C)²) = (-0.035 x (20)² = -13.6ppm
