(音叉晶振FC-135/SMD3215 32.768KHz)

为何不建议音叉KHz晶振过超声波？原因有二：

1、Tuning fork products oscillate at frequency bands that are close to the washing frequency of ultrasonic cleaning machine, which may cause resonance deteriorating the electrical characteristics in devices, and even damaging the overall structure of devices. Therefore, using ultrasonic cleaning machine to clean tuning fork devices should be avoided. If the use of this method to clean tuning fork devices is required, it’s suggested to check the functionality of devices before and after the cleaning process.

若超声波清洗频率与音叉晶振频率接近，可能引发共振，使晶振的电气特性恶化，甚至破坏晶振的整体结构。因此，请应避免使用超声波清洗音叉晶振。如果需要使用，建议在清洁之前和之后对晶振功能进行确定。

2、Avoid mounting and processing by Ultrasonic welding this method has a possibility of an excessive vibration spreading inside the crystal products and becoming the cause of characteristic deterioration and not oscillating.

请避免使用超声波安装和超声波焊接音叉KHz晶振晶振，因为超声波有可能产生过度振动，若其危害扩散到晶体内部，会引发晶振电气特性恶化，造成停振。
