#151558 - Do never solder the can!!! Responding to: ???'s previous message |
The crystal is commonly mounted within the can by the help of a polymeric glue. Heating up the can by soldering can damage the glue, resulting in a drastical increase of mechanical dampening of crystal. The consequence can be a shift of frequency or even a refuse of start-up. So, normally, you should not solder the can.
