The metal case inside of the molding compound may be exposed on the top or bottom of this product.
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
