Does Micron offer lead-free (Pb-free) parts?
Yes. Micron offers certain Pb-free products. For more information regarding Micron’s Pb-free process technologies, contact our Quality Assurance Department.
The first phase of Micron’s “green” program includes a conversion to Pb-free products. What does Pb-free mean?
Micron’s Pb-free program incorporates manufacturing processes that reduce the amount of Pb in our semiconductor products so only trace amounts remain. We do not intentionally add Pb* to our component plating alloys, solder balls, or solder interconnects—either surface mount or flip-chip. Micron also offers Pb-free modules. Micron's Pb-free module level products contain no Pb other than the PbO (lead-oxides) which are exempt from Directive 2002/95/EC (see Article 4, Section 2 and Section 7 of the Annex.) Using these processes, Micron has attained internationally recognized Pb-free levels, including those specified in the European Union’s RoHS Directive, while meeting our customers’ performance needs.
*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.
What materials does Micron use in its Pb-free semiconductors?
- For solder balls, Micron is replacing tin-lead alloys (Sn36Pb2Ag) with a tin (Sn), silver (Ag), and copper (Cu) ternary alloy: Sn3.0Ag0.5Cu, or SAC305.
- 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.
Are Micron’s Pb-free products RoHS-compliant? What does 5/6 RoHS mean?
Yes. Directive 2002/95/EC, Restriction of the use of certain Hazardous Substances in Electrical and Electronic Equipment (RoHS), does apply to 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 Pb-free module level products do contain electronic ceramic passive parts that may use PbO (lead-oxides) which are exempt from Directive 2002/95/EC (see Article 4, Section 2 and Section 7 of the Annex.)

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 industries have received exemptions from the RoHS directive. In fact, until there is conclusive data to bring the industry to a consensus regarding RoHS 5/6 and RoHS 6/6, Micron will continue to support both RoHS standards.
Do Micron’s Pb-free products comply with China RoHS requirements? Does Micron label its products with the Environmental Protection Use Period?
Micron’s Pb-free component, die, and wafer-level products are fully compliant with the China RoHS requirements. Micron’s Pb-free modules do contain PbO (lead oxide), which is present in the ceramics of certain passive electronic components such as resistors and capacitors.
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. Micron can supply the compliance information necessary for our direct customers to label their products in accordance with all of the current environmental product legislation.
How do I get Micron's RoHS certificate of compliance?
Micron’s RoHS Certificate of Compliance may be downloaded via our Pb-Free Engineering page.
How does Micron characterize green products?
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 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
<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.
Micron’s green parts are certified for a surface mount temperature of 260°C.
*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.
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.
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 Purchasing page).
Where can I find Micron's green and Pb-free component part numbers?
Micron’s full line of Pb-free memory products can be found on our Web site, as indicated in the part list tables for each product type. To perform a quick compliance check on a single part number, use the "Check RoHS Compliance" tool. Micron’s Pb-free products have distinct part numbers. For information on green products, please contact your local Micron sales representative.
