Green Engineering FAQs

Green Engineering(10)
Are Micron’s Pb-free products RoHS-compliant? What does 5/6 RoHS mean?

Yes. Directive 2011/65/EU (replacing the Directive 2002/95/EC), Restriction of the use of certain Hazardous Substances in Electrical and Electronic Equipment (RoHS), does impact Micron's semiconductor products. The purpose of this directive is to restrict the use of certain hazardous substances in electrical and electronic equipment and protect human health and the environment. Micron’s products have always been 5/6 RoHS compliant, meaning they contain Pb solder, but otherwise comply with RoHS regulations (they meet five of six stipulations). Micron’s Pb-free products are completely RoHS compliant.

Micron's RoHS compliant module level products do contain electronic parts that may use Pb for applications exempt from Directive 2011/65/EU (see Article 4, Annex 3). Please contact your sales/marketing representative for more information.

The European Commission FAQ sheet distributed under the Directorate-General Environment may serve as a formal (but not legally binding) point of reference.

Do Micron’s Pb-free products comply with China RoHS reporting requirements? Does Micron label its products with the Environmental Protection Use Period?

Micron’s Pb-free component, die, and wafer-level products do not contain any of the six substances restricted by the China RoHS. Micron’s modules may contain Pb in both not exempted and exempted EU RoHS applications (where not reliable Pb-free alternatives are available in the market).

Micron’s products are not sold directly to consumers. The EPUP and other marking and labeling requirements apply only to the products sold directly on the consumer market. For more information contact your sales/marketing representative.

*These substances are not intentionally added by Micron during the manufacturing process but can be present in trace amounts in the raw materials used to manufacture the finished products.

 

Is Micron aware of REACh requirements?

Micron is fully aware of product requirements coming from Regulation 2006/1907/EC, Registration, Evaluation Authorization and Restriction of Chemicals. Micron constantly monitors new additions to the Candidate List and timely verifies if any Substance of Very High Concern is used in the manufacturing processes and the potential impact on the final products. Micron is committed to provide our customers with information about substances in its products as required.

For any documentation need, please contact your sales representative.

How does Micron define green products?
In addition to being RoHS compliant, Micron's Green packages do not contain substances that have been identified as harmful to the environment or known to pose serious reliability: bromine, chlorine, antimony containing substances, and inorganic red phosphorus. These substances are not intentionally added to packaging materials such as encapsulants, die attach materials, underfill epoxies, and substrates. The maximum trace amounts of these substances allowable in Micron’s green packages are listed below.

<900 ppm Chlorine
<900 ppm Bromine
<1500 ppm Chlorine & Bromine
<900 ppm Antimony
<100 ppm Red Phosphorus

Please note that while our Pb-free and green products do not contain any intentionally added Pb, our Pb-free parts are not necessarily green, since they may contain halogen or antimony compounds.

*These substances are not intentionally added by Micron during the manufacturing process but can be present in trace amounts in the raw materials used to manufacture the finished products.
Does Micron still make parts that comply with RoHS 5/6 standards?

Yes, along with our Pb-free product line, Micron also supports RoHS 5/6 products. We recognize that certain applications are exempt from the RoHS directive.

Where can I find Micron's green and RoHS products part numbers?

Micron’s full line of RoHS compliant memory products can be found in the part list tables for each product type. To perform a quick compliance check on a single part number, use the "Part Number Search" tool. For information on green products, please contact your local Micron sales representative.

How do I get Micron's RoHS certificate of compliance?

You can find a part-specific RoHS Certificate of Compliance by navigating to the part detail page or using the main products family navigation.                       

How do Micron’s green products comply with international standards?
Micron’s green engineering program is RoHS-compliant and conforms with most of the world’s emerging environmental standards, including those in Asia and Europe.
What materials does Micron use in its Pb-free semiconductors?
  • For solder balls, Micron is replacing tin-lead alloys (Sn36Pb2Ag or Sn37Pb ) with a tin (Sn), silver (Ag), and copper (Cu) alloys (e.g., SAC105, SAC305, SAC405, LF35).
  • For solder paste on modules, Micron is replacing Sn37Pb with Sn3.8Ag0.7Cu.
  • For leaded TSOP, Micron is replacing 90Sn10Pb with matte Sn plating.

These substitutions ensure Micron’s Pb-free parts are RoHS-compliant. Parts are certified for a surface mount temperature of 260°C.

When will Micron complete its transition from Pb-free to green products?
Micron can currently provide Pb-free and green product to customers who require it. The availability of these products is highly dependent on customer demand, as well as on the availability of "green" non-memory components and materials.

Please contact your local Micron sales representative for more information (look up regional sales representatives on the How To Buy page).
