5. Reference Layout

1. The back plate of the IC should connect to GND.2. When using cylinder crystal, please take special care as below:

(1) Please don’t apply solder to the body directly, as it may cause characteristic deterioration.(2) Please fix the unit firmly with elastic glue on the board.(3) Please don’t cut or bend the leads within 0.5 mm from the base of the cylinder body.(4) Please don’t use ultrasonic washing and ultrasonic welding on the unit, because it may be

damaged.
