The failure rate (λ) and mean time between failures
(MTBF= 1/λ) is calculated at max output power and an
operating ambient temperature (TA) of +40°C. Flex uses
Telcordia SR-332 Issue 2 Method 1 to calculate the mean
steady-state failure rate and standard deviation (σ).
Telcordia SR-332 Issue 2 also provides techniques to
estimate the upper confidence levels of failure rates based
on the mean and standard deviation.
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.
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
work force, contribute to the high quality of the products.
Warranty period and conditions are defined in Flex General
Terms and Conditions of Sale.
Limitation of Liability
Flex does not make any other warranties, expressed or
implied including any warranty of merchantability or fitness
for a particular purpose (including, but not limited to, use in
life support applications, where malfunctions of product can
cause injury to a person’s health or life).
