Physical and Environmental Characteristics
| Test | Condition |
|---|---|
| Humidity | Subject crystal at 40°C ±2°C and 90%-95% RH for 96 ±4 hours. Release into room conditions for 1 hour prior to measurement. |
| High Temperature Exposure | Subject crystal to 85°C ±5°C for 96 ±4 hours. Release into room conditions for 1 hour prior to measurement. |
| Low Temperature | Subject crystal to -20°C ±5°C for 96 ±4 hours. Release into room conditions for 1 hour prior to measurement. |
| Mechanical Shock | Drop crystal randomly onto a concrete floor from a height of 75cm, 3 times. |
| Temperature Cycling | Subject crystal to -30°C for 30 min, followed by +85°C for 30 min. Repeat 5 times with a transfer time of 15 sec. at room condition. Release into room temperature for 2 hours prior to measurement. |
| Vibration | Subject 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°C ±5°C 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°C ±5°C 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 the direction of terminals (without shock) 0.5kg for 10±1 sec. Crystal shall show no evidence of damage and fulfill initial electric characteristics. 2) Bending Test: Lead shall withstand 90-degree bending at its stem in both directions. Crystal shall show no evidence of damage and fulfill initial electric characteristics. |
