关于晶振跌落问题，解释如下：

Our crystal products are designed and manufactured to resist physical shocks. However, in the event the crystal is subjected to excessive impact such as being dropped onto the floor or giving shocks during mounting. Need to make sure its satisfactory performance before using it.

（内部产生频率的核心部件为石英晶片，具有易碎性）

产石英晶体产品（包括石英晶体谐振器和石英晶体振荡器两大类）经过精心设计和制造，可抵抗物理冲击。但是，如果晶体受到过度冲击，例如掉落到地板上或在安装过程中产生冲击，则需要在使用前对其进行电气参数确认，以确保其性能依旧满足要求。
