Freescale is transitioning its portfolio to RoHS compliant and high temperature attach qualified products for lead (Pb) free board-attach assembly processing. Freescale is shipping high volumes of RoHS compliant products today, and continues to ramp production of RoHS compliant products in advance of the July 1, 2006 deadline.
RoHS Compliant/Lead (Pb) Free
Initiatives
Implementation of robust RoHS Compliant/Lead (Pb) free plating finishes across multiple packages, actories and subcontractors;
-
Qualification of RoHS Compliant/Lead (Pb) free solder balls for area array packages;
-
Incorporation of RoHS Compliant/Lead (Pb) free terminations and high-temperature reflow capability into new product designs;
-
Introduction of Bromide (Br) free encapsulants and organic substrates when existing materials change;
- Elimination of brominated flame retardants.

Technical Plating Solutions - Matte Tin
For our copper (Cu) lead frame wire bond products, an electroplated, pure matte Sn finish has
been selected to replace the SnPb finish on the Cu pins. Selection of matte Sn was
determined through extensive evaluations comparing with other Pb-free
finish materials in the aspects of manufacturability, reliability and
cost. Matte Sn provided the best balance for the three criteria and has
been the dominant choice for Pb-free products by a majority of the
semiconductor suppliers and assembly houses.
Matte Sn provides the best compatibility to all existing electronic solders, good corrosion
resistance, and acceptable wettability. Additionally, Sn plating chemistry
has good stability and is easier to control than alloyed Sn finishes.
These properties make Sn the preferred substitute for SnPb on the Cu
termination. The use of a Cu base material for the lead frames results
in good adhesion strength of mold compounds and gives good package
integrity.
Green Initiatives
Freescale is proactively pursuing the elimination of brominated flame-retardants as
part of our Environmental Product initiatives.

Compliance Procedures
Freescale's Environmental Product Program is designed to comprehend and assure
compliance to regulatory requirements, collect, calculate, retain and
report accurate material content,
and effectively communicate critical information
to our customers, suppliers and employees.
Freescale requires the following documents from our suppliers:
- Signed declarations of compliance stating that their materials
DO NOT contain banned substances at the homogeneous material level.
- Material content reports disclosing what IS
contained in the piece parts and assembly materials.
Freescale's product content data is reported in ranges of weights and concentrations
which reflect the natural variations that occur in manufacturing and
assembly processes. Freescale's standardized process provides material content data at the finished
product level without compromising the formulation of our suppliers' products. Material content data is more statistically significant when
specified as a range rather than as fixed values for each substance. Freescale provides material composition declarations based on the NEMI /
IPC-1752 format.
Freescale calculates material content
reports for our products using a combination of measured weight data of
the piece parts and material content reports from our suppliers. Some
finished devices are analyzed from time to time to confirm that our
disclosure data and calculations are accurate.
Current Regulatory Requirements
ELV:
End-of-Life Vehicle Directive, 2000/53/EC. This European Union
directive restricts the presence of lead, cadmium, mercury, and hexavalent
chromium in vehicles. It also sets requirements for increasing reuse,
recycling, and other forms of recovery of end-of life vehicles (ELV) and
their components.

RoHS: Reduction of Hazard Substances Directive,
2002/95/EC. This European Union directive applies to certain
electrical and electronic equipment that are put on the market in member
countries. The ROHS directive requires the elimination of lead, cadmium,
mercury, hexavalent chromium, and certain flame retardants, biphenyls
(PBB) and polybrominated diphenyl ethers (PBDE), from electrical and
electronic products by July 1, 2006.

China – RoHS.
China released its RoHS legislation on February 28, 2006. The
marketing requirements are scheduled for implementation on March 1,
2007. While similar to the European RoHS Directive, there will be
differences. Freescale continues to closely monitor these developments.
WEEE:
Waste of Electrical and Electronic Equipment Directive,
2002/96/EC. This European Union directive applies to the
collection, treatment, recovery and recycling of electrical and electronic
equipment in the European Union member countries.
