Voltage Regulator Module (VRM) and Enterprise Voltage Regulator-Down (EVRD) 10.2 Design Guidelines

Voltage Regulator Module (VRM) and Enterprise Voltage 35
Regulator-Down (EVRD) 10.2 Design Guidelines
9 Lead Free (Pb Free)
The use of lead in electronic products is an increasingly visible environmental and political
concern. The drivers for the reduction or elimination of lead in electronic products include:
• Customer desire for environmentally friendly (‘green’) products.
• Manufacturer desire to be environmentally friendly, and be perceived as such.
• Government initiatives regarding recycling of electronic products.
• Planned and potential legislation.
The most notable legislation is the European Union (EU) Restriction on Hazardous Materials
directive, also known as RoHS. The commission directive may be found at the following URL:

European Union “Member States shall ensure that, from 1 July 2006, new electrical and electronic
equipment put on the market does not contain lead…” Each EU country will implement this law
and establish penalties and fines for non-compliance. The RoHS directive includes certain
exemptions:
• Lead in high melting temperature type solders (i.e. tin-lead solder alloys containing more than
85% lead).
• Lead in solders for servers, storage and storage array systems (exemption granted until 2010).
• Lead in solders for network infrastructure equipment for switching, signaling, transmission as
well as network management for telecommunication.
• Lead in electronic ceramic parts (e.g. piezoelectronic devices).

The VRM10.2 lifetime is expected to extend beyond July 1, 2006.
Intel recommends that you consider Pb Free manufacturing processes and components for the
module and module connector.
