Note: TCXO’s are precision subsystems with tolerances measured to ±0.01 ppm. Non-Hermetically sealed

TCXO’s should not be subjected to a wash process that will immerse the TCXO in solvents. NO CLEAN is the

recommended procedure. The Z5 series of TCXO’s has been designed for pick and place reflow soldering. The

suggested reflow profile is shown above. The TCXO may be reflowed two times. Typical frequency shift as a

result of reflow is <1.0 ppm per reflow. VI recommends waiting at least two hours after reflow before measuring the

unit.
