Why is Ecliptek transitioning to RoHS (Pb-Free) components and
assemblies?
Ecliptek is introducing an RoHS Compliant,
Lead-Free (Pb-free) Program in response to concerns about the environmental
impact of Lead (Pb) and other hazardous substances used in the manufacturing of
electronic components and assemblies. Regulatory groups around the world have
initiated legislation calling for companies to utilize Pb-free manufacturing
processes and components. Because of this legislation, many of our customers
are now requesting products that utilize Pb-free manufacturing processes and
components which are compliant to the RoHS standard.

What legislation or directives have been established by the various
regulatory groups?
In December 2002, the European Union
Parliament approved the content of two directives to better control the
management of waste electronic equipment. The two directives are the Waste from
Electrical and Electronic Equipment (WEEE) and the Reduction of Hazardous
substances (RoHS). The WEEE addresses the collection and treatment requirements
of waste electronic equipment for the member countries. The RoHS directive sets
phase out dates for the use of Lead (Pb) and several other hazardous
substances contained in electronic products. The RoHS directive requires that
on July 1, 2006, the targeted materials shall no longer be contained in the
electronic products unless there is an exemption provided in the rule.

-
Is RoHS compliance mandatory throughout the world?
RoHS
compliance is only mandatory on products shipped into the European Union (EU)
or member countries. However, since many other jurisdictions have similar or
pending legislation and since many manufacturers products may eventually find
their way into the EU, Rohs compliance is having a global effect.
