This purely cosmetic and does not have any effect on quality, reliability or electrical specs. N.C. - Do not connect. *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 VDD - Main power supply. 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 Specifications (characteristics) Refer to application manual for details.

The environmental management system (EMS) management that was established by the International operates under the ISO 14001 environmental management standard. Standards Organization in 1996 against the background of All of our major manufacturing and non-manufacturing sites, in growing concern regarding global warming, destruction of the ozone layer, and global deforestation. Japan and overseas, completed the acquisition of ISO 14001 certification. WORKING FOR HIGH QUALITY In order provide high quality and reliable products and services IATF 16949 is the international standard that added the than meet customer needs, Seiko Epson made early efforts towards sector-specific supplemental requirements for automotive obtaining ISO9000 series certification and has acquired ISO9001 for industry based on ISO9001. all business establishments in Japan and abroad. We have also acquired IATF 16949 certification that is requested strongly by major automotive manufacturers as standard. Explanation of the mark that are using it for the catalog Pb free.
