The RoHS WEEE directive
restricts the use of six hazardous materials
in the manufacture
of various types of electronic and electrical equipment.
RoHS COMPLIANT also referred to as
RoHS 5 or RoHS 20

RoHS Directive | RoHS
Standard
The Restriction of Hazardous
Substances Directive (RoHS) 2002/95/EC was adopted in February
2003 by the European Union.
RoHS is often referred
to as the "lead-free" directive.
The
RoHS directive took effect on
July 1, 2006, but is not a law; it is simply a directive.
It is closely
linked with the Waste Electrical and Electronic Equipment Directive (WEEE)
2002/96/EC which sets collection, recycling and recovery targets for
electrical goods and is part of a legislative initiative to solve the
problem of huge amounts of toxic e-waste.
|
 |
The
RoHS WEEE compliance directive places
the responsibility
of compliance on the "producer" of the equipment.
This RoHS Directive
is part of an ever-increasing push for more environmentally sound
manufacturing procedures as demand for electrical and electronic goods
rises.
RoHS will have significant impact - on a global scale - with
manufacturers being prohibited from placing products on the market that
contain banned substances. |

RoHS
Banned Substances |
RoHS restricts
the use of the following 6 substances:
- Lead
- Mercury
- Cadmium
- Chromium VI
- PBB
- PBDE
PBB and PBDE are flame retardants used
in some plastics.
The maximum RoHS imposed
concentrations are 0.1% (except for Cadmium which is limited to
0.01%) by weight of homogeneous material. This means that the
limits do not apply to the weight of the finished product, or
even to a component, but to any single substance that could
(theoretically) be separated mechanically — for example, the
sheath on a cable or the tinning on a component lead.

Press Statement July 01-2006
RoHS Criticism
Restricting lead content in solders for
electronics requires expensive retooling of the assembly lines and
different coatings for the leads of the electronic parts. The
alternatives to the solders typically have higher melting points (up to
260 °C, instead of just 215 °C), requiring different materials for chip
packagings and for some circuit boards; the overheating may also affect
reliability of some semiconductors.
The alternative solders are also harder, resulting in slow development
of cracks (instead of plastic deformation, as the softer Sn-Pb solder
does) because of thermal expansion and contraction as some parts heat up
and cool down during operation, thus significantly impairing long-term
reliability and device lifetime. Some countries therefore tend to exempt
medical and telecommunication infrastructure products from the
legislation.
