VDD - Connected to a positive power supply.
The metal case inside of the molding compound may be exposed on the top or bottom of this product.
GND - Connected to a ground.
This purely cosmetic and does not have any effect on quality, reliability or electrical specs.
*Stop using the glue
Any glue must never use it after soldering LC-package to a circuit board.This product has glass on the back side of a package.When glue invasions
between circuit board side and glass side, then glass cracks by thermal expansion of glue.In this case a crystal oscillation stops.Consider glue
abolition or glue do not touch to LC-package
