ENVIRONMENTAL CHARACTERISTICS
Performance
Requirements
Test Item
Test Conditions
Moisture:
Keep the resonator at 40°±2°C and 90% to 95% RH for 60 hours.
Then release the resonator into ambient room conditions for 1
hour prior to measurement.
Vibration:
Subject the resonator to vibration for 1 hour in each of three
mutually-0perpendicular planes. Amplitude 1.5mm, 10Hz to 55z.
Mechanical
Shock:
Drop the resonator randomly onto a concrete floor from a height
of 1 metre. Three times.
Reflow
Soldering:
Preheating at 150°C to 175°C for one minute. Then expose the
resonator to more than 200°C with the maximum temperature not
higher than 230°C±5°C. Then release the resonator into ambient
room conditrions for 1 hour.
Solderability:
Dip the resonator terminals no closer than 1.5mm into the solder
bath at 230°C±5°C for 5 seconds±1 second.
Min. 95% of lead terminals surface shall
be covered with solder.
High
Temperature
Exposure:
Subject the resonator to 85°C±2°C for 96 hours. Then release the
resontor into ambient room conditions for one hour.
The resonator shall fulfill the
specifications stated in 'Electrical
Specifications' above.
The resonator shall fulfill the
specifications stated in 'Electrical
Specifications' above.
