See package handling notes  
The CX crystal is hermetically sealed in a ceramic package. Normal  
handling and soldering precautions for small, low thermal mass parts  
are adequate when installing or testing CX crystals. CX crystals may  
be wave soldered with proper precaution taken to avoid desoldering  
the leads. A slow machine rate or too high a pre-heat temperature or  
solder bath temperature may damage the crystals. Lead to package  
solder interface temperature should not exceed 175°C, glass lid  
to package seal rim temperature should not exceed 210°C. If  
the seal rim reaches temperatures above the maximum specified, the  
package may lose its hermeticity. Loss of hermeticity results in a  
frequency decrease and motional resistance increase.  
Note: The characteristics of the frequency temperature stability follow  
that of AT-Cut Thickness Shear mode.
