Marking Permanency Per MIL-STD-202G, Method 215J. Solder Process Recommendations: RoHS compliant, lead free. See solder profile on page 4. In-line reflow: Refer to recommended reflow pre-heat and reflow temperatures on page 4. Package material consist of Ryton R-4 high temperature cover with FR4 substrate. Component solder is Pb free high temperature eutectic alloy with a melting point of 221°C. In-line oven profile: We recommend using KIC profiler or similar device placing one of the thermocouples on the device to insure that the internal package temperature does not exceed 221°C. Removal of device: If for any reason the device needs to be removed from the board, use a temperature controlled repair station with profile monitoring capabilities. Following a monitored profile will insure the device is properly pre-heated prior to reflow. Refer to IPC 610E for inspection guidelines. Recommended Cleaning Process: (If required) Device is non-hermetic, water resistance with four weep holes, one in each corner to allow moisture to be removed during the drying cycle. We recommend in-line warm water wash with air knife and drying capabilities. If cleaner does not have drying capability, then use hot air circulated oven. Boards should be placed in the oven vertically for good water runoff. Device must be dried properly prior to use! Note: If saponifier is used make sure the device is rinsed properly to insure all residues are removed. PH of saponifier should not exceed 10. Drying Temperature: Between 85 to 100°C. Drying Time: Time will vary depending on the board size. Caution: Do not submerge the device! Notes: 1. Frequency stability vs. change in temperature. [±(Fmax - Fmin)/(2*Fo)]. 2. Initial calibration @ 25°C. For OCXO with voltage control option, the control voltage must be fixed. 3. After 10 days of operation 4. Inclusive of calibration @ 25°C, frequency vs. change in temperature, change in supply voltage (±5%), load change (±5%), shock and vibration and 20 years aging 5 Minimum "Power On Time" after rail rises from 0 to within +/-5% of Vcc = 1 second.
