*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

PROMOTION OF ENVIRONMENTAL MANAGEMENT SYSTEM
CONFORMING TO INTERNATIONAL STANDARDS
At Seiko Epson, all environmental initiatives operate under the
Plan-Do-Check-Action (PDCA) cycle designed to achieve continuous
ISO 14000 is an international standard for environmental
improvements. The environmental management system (EMS)
operates under the ISO 14001 environmental management standard.
All of our major manufacturing and non-manufacturing sites, in
Japan and overseas, completed the acquisition of ISO 14001
certification.
management that was established by the International
Standards Organization in 1996 against the background of
growing concern regarding global warming, destruction of
the ozone layer, and global deforestation.
WORKING FOR HIGH QUALITY
In order provide high quality and reliable products and services
than meet customer needs,
ISO/TS16949 is the international standard that added the
sector-specific supplemental requirements for automotive
industry based on ISO9001.
Seiko Epson made early efforts towards obtaining ISO9000 series
certification and has acquired ISO9001 for all business
establishments in Japan and abroad. We have also acquired ISO/TS
16949 certification that is requested strongly by major automotive
manufacturers as standard.
