PROCESS RECOMMENDATIONS
TABLE 5.0
Soldering Process
See the solder profile on page 2.
Wash
Ultrasonic cleaning is not recommended
Notes:
1) Initial calibration @ 25C
2) Frequency vs. temperature stability
3) Inclusive of calibration, operating temperature range, suppl y voltage change, shock and
vibration and aging (20 years).
4) Specifications at time of shipm ent after 48 hours of operation.
5) Measured @ 25C, within 5 minutes, the unit will be within +/-0.1ppm of its reference
frequency, measured after 30 minutes of continuous operation at a stable 25C.
