Reliability
The Mean Time Between Failure (MTBF) is calculated at full output
power and an operating ambient temperature (TA) of +40°C, which is a
typical condition in Information and Communication Technology (ICT)
equipment. Different methods could be used to calculate the predicted
MTBF and failure rate which may give different results. Ericsson Power
Modules currently uses Telcordia SR332.
Predicted MTBF for the series is:
-
1.79 million hours according to Telcordia SR332, issue 1, Black
box technique.
Telcordia SR332 is a commonly used standard method intended for
reliability calculations in ICT equipment. The parts count procedure used
in this method was originally modelled on the methods from MIL-HDBK-
217F, Reliability Predictions of Electronic Equipment. It assumes that no
reliability data is available on the actual units and devices for which the
predictions are to be made, i.e. all predictions are based on generic
reliability parameters.
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 Ericsson Power Modules
products include:
-
Lead in high melting temperature type solder (used to solder the
die in semiconductor packages)
-
Lead in glass of electronics components and in electronic ceramic
parts (e.g. fill material in chip resistors)
-
Lead as an alloying element in copper alloy containing up to 4%
lead by weight (used in connection pins made of Brass)
The exemption for lead in solder for servers, storage and storage array
systems, network infrastructure equipment for switching, signaling,
transmission as well as network management for telecommunication is
only utilized in surface mount products intended for end-users’ leaded
SnPb Eutectic soldering processes. (See ordering information table).
Quality Statement
The products are designed and manufactured in an industrial
environment where quality systems and methods like ISO 9000, 6σ
(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 our products.
Warranty
Warranty period and conditions are defined in Ericsson Power Modules
General Terms and Conditions of Sale.
Limitation of Liability
Ericsson Power Modules 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).
