产32.768KHz晶振过超声波注意事项如下：

The 32.768KHz crystal should be laid as far away as possible from the ultrasonic sealing/ welding position. The ultrasonic operation should avoid 30~32KHz so as not to cause resonation with 32.768KHz, and shall not last too long as well, so as not to result in internal structural damage to the crystal.

32.768KHz晶振尽量远离过超声波封焊位置。超声波作业时，请避免30~32KHz超声频率，且超声波作业不宜过长，以免与晶振32.768KHz共振，造成晶振内部结构性损坏。

After ultrasonic sealing/welding operations, the failure rate of our anti-ultrasonic crystals can be controlled within 3/1000.

抗超声波晶振在经过超声波封焊作业后，不良率可控制在千分之三以内。
