#151563 - Do never solder the can... Responding to: ???'s previous message |
Kai Klaas said:
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.
Kai Nice point Kai ,I have seen people soldering Crystals even in motherboards . Some good manufacturers provide a sleve on the crystal , and people still scratch it and apply as much solder and heat to it as they can :) .I personally try to make a bridge and tighten the XTAL to the below unmasked solid ground plane.
