Pb-free / ROHs / REACH info
Microsemi CMPG's Pb-Free/RoHS StrategyMicrosemi CMPG maintains a policy of environmental awareness and responsibility and in so doing we continue to lead with manufacturing strategies consistent with the best practices in the industry. Improvements in our production processes include the elimination of certain chemicals from our products, and partnership with contractors who demonstrate compliance with the appropriate environmental standards. Microsemi CMPG has made available 'Pb-Free' products to support customers who require them to comply with the EU RoHS directive.
Other Microsemi CMPG customers have utilized an exception to the above directive which permits them to continue to use Pb in their products for a limited time, until 2010. In consideration of this exemption expiration date, Microsemi CMPG is now completing the migration of all leadframe based IC products to a fully compatible material set with lead plating changed to matte tin. All of the Microsemi CMPG leadframe based products with a matte tin finish are backwards compatible with the traditional SnPb solder processes. In addition, a post plating bake has been implemented at the assembly subcontractors as a whisker mitigation process.
Microsemi CMPG is also currently developing a roadmap for the conversion of the BGA based IC products to an environmentally friendly material set with a solder ball composition of tin/silver/copper (SAC). SAC is not backwards compatible with the traditional SnPb solder processes.
All new Microsemi CMPG products are designed in accordance with environmentally friendly practices and in future, designs utilizing Pb will no longer be available.
RoHS Implications
The European Union directive Restriction of Hazardous Substances (RoHS) defines specific hazardous materials that must be eliminated by July 2006.
Of the six listed "hazardous" materials Hg, Cr6+, Cd, PBB, PBDE are either absent from or only present as trace impurities in the integrated circuits supplied by Microsemi CMPG.
The sixth material, Pb has been used in the device terminals of the majority of plastic assembled integrated circuits that have been manufactured over the last 50 years.
In support of the environmental requirements, Microsemi CMPG is producing Pb-free IC devices and all of these are compliant with the Restriction of Hazardous Substances directive. Microsemi CMPG certifies the material content of its IC devices with an "Environmental Declaration".
Reflow Temperature
To be compatible with Pb-free, IC packages need to withstand a higher reflow temperature, i.e. up to 260°C for the smaller package types. Therefore all RoHS compliant products supplied by Microsemi CMPG will be qualified to withstand these higher reflow temperatures as warranted by our subcontractors. In general, Microsemi CMPG is using the Classification Reflow profile as defined in JEDEC J-STD -020 for both lead-frame and ball grid packages. For more information see ?Soldering Profiles?.
Availability of Pb-free Products
Microsemi CMPG has now launched Pb-free versions for many of its products and they can be identified in the "Lead-free Selector Guide" on zarlink.com.
If your specific product need is not shown on zarlink.com with a Pb-free version as available please contact your local Sales Office.
Pb?free Product Identification
Microsemi CMPG is adopting the key requirements of the JEDEC standard J-STD-609 ?Marking and Labeling of Components, PCBs and PCBAs to Identify Lead (Pb), Pb-Free and Other Attributes?.
Registration, Evaluation, Authorisation and restriction of CHemicals (REACH) regulation of Substances of Very High Concern (SVHC)
Microsemi CMPG is dedicated to being an environmentally conscious company and strives to be in compliance with REACH, the European Union (EU) Regulation of Substances of Very High Concern (SVHC).

Humidity Indicator Cards (HIC)
In addition, Microsemi CMPG is converting to Cobalt Dichloride free Humidity Indicator Cards (HIC).
The appearance of the environment friendly HIC card is changed only to make it clear that they are cobalt dichloride free. The performance of the new card and the currently used card is equivalent. Please see below for example images of the existing and new cards, and an illustration of the relevant portion of Jedec Standard J-STD-033.
