Physical and Environmental Characteristics
Humidity: Subject the crystal at 40℃±2℃ and 90- 95 RH for 96±4 hours. Then release the crystal into room conditions for 1 hour prior to measurement.
High Temperature Exposure: Subject the crystal to 85℃±5℃ for 96±4 hours. Then release the crystal into room conditions for 1 hour prior to measurement.
Low Temperature: Subject the crystal to -20℃±5℃ for 96±4 hours. Then release the crystal into room conditions for 1 hour prior to measurement.
Mechanical Shock: Drop the crystal randomly onto a concrete floor from a height of 75cm, 3 times.
Temperature Cycling: Subject the crystal to -30℃ for 30 min. followed by +85℃ for 30 min. Cycling repeated 5 times with a transfer time of 15sec. at room condition. Release resonator into room temperature for 2 hours prior to measurement.
Vibration: Subject the crystal to vibration for 2 hours each in x, y, and z axes with an amplitude of 1.5mm. Frequency varied uniformly between 10-55 Hz.
Resistance to Solder Heat: Dip crystal terminals (no closer than 2 mm) into solder bath at 260℃±5℃ for 5±1 sec. Release into room temperature for 1 hour prior to measurement.
Solder Ability: Dip crystal terminals (no closer than 2 mm) into solder bath at 235℃±5℃ for 3±0.5 sec. More than 95% of the terminal surface shall be covered with fresh solder.
Lead Fatigue:
1) Pulling Test: Weight along terminal direction without shock, 0.5kg for 10±1sec. Crystal shall show no damage and fulfill initial electric characteristics.
2) Bending Test: Lead subject to withstand 90-degree bending at its stem towards both directions. Crystal shall show no damage and fulfill initial electric characteristics.
