Mounting method to PCB
When the crystal products need to be lay down please fix to PCB securely
If the crystal is used with mechanical vibration location, please put cushion in between PCB or fix with
elasticity glue (Silicon etc) as shown in below figure. Please donât gluing hermetic seal grass
When the crystal products need to be mounted vertically, gap between crystal units and PCB
more than 3mm for 3Ã8 type , more than 2mm for 2Ã6 type is recommended
