Compatibility with RoHS requirements
The products are compatible with the relevant clauses and
requirements of the RoHS directive 2002/95/EC and have
a maximum concentration value of 0.1% by weight in
homogeneous materials for lead, mercury, hexavalent
chromium, PBB and PBDE and of 0.01% by weight in
homogeneous materials for cadmium.
Exemptions in the RoHS directive utilized in Flex products
are found in the Statement of Compliance document.
Flex fulfills and will continuously fulfill all its obligations
under regulation (EC) No 1907/2006 concerning the
registration, evaluation, authorization and restriction of
chemicals (REACH) as they enter into force and is through
product materials declarations preparing for the
obligations to communicate information on substances in
the products.
Quality Statement
The products are designed and manufactured in an
industrial environment where quality systems and methods
like ISO 9000, Six Sigma, and SPC are intensively in use to
boost the continuous improvements strategy. Infant
mortality or early failures in the products are screened out
and they are subjected to an ATE-based final test.
Conservative design rules, design reviews and product
qualifications, plus the high competence of an engaged
