PHYSICAL AND ENVIRONMENTAL CHARACTERISTICS
3-1. Humidity
Subject the crystal at 20℃± 2℃ and 90％ - 95％ RH for 96±4 hours Then
release the crystal into the room conditions for 1hour prior to the
measurement﹒
3-2. High Temperature Exposure
Subject the crystal to 70℃± 5℃ for 96±4 hours﹒ Then release the
crystal into the room conditions for 1hour prior to the
measurement﹒
3-3. Low Temperature
Subject the crystal to -10℃± 5℃ for 96±4 hours﹒Then release the
crystal into the room conditions for 1hour prior to the
measurement﹒
3-4. Mechanical Shock
Drop the crystal randomly onto a concrete floor from the height of
50cm 3 times﹒
3-5. Temperature Cycling
Subject the crystal to -20℃ for 30 min. followed by a high
temperature of +70℃ for 30 min. Cycling shall be repeated 5times
with a transfer time of 15sec. at the room condition﹒ Then release
the resonator into the room temperature for 2hours prior to the
measurement﹒
3-6. Solder Ability
Dip the crystal terminals no closer than 2 mm into the solder bath
at 235℃± 5℃ for 3±0.5 sec .more than 95％ of the erminal surface of
the crystal shall be covered with fresh solder.
3-7. Lead Fatigue
1) Pulling Test
Weight along with the direction of terminals without any shock
0.5kg for 10±1sec.; The crystal shall no evidence of damage and
shall fulfill all the initial electric characteristics.
2) Bending Test
Lead shall be subject to withstand against 90 degree bending at its
stem‧This operation shall be done towards both direction; The
crystal shall no evidence of damage and shall fulfill all the
initial electric characteristics.
3-8．Reflow soldering
This products can reflow soldering
4. REVIEW OF SPECIFICATION
When something get doubtful with this specifications,we shall
jointly work to get an agreement.
