Lead-Free/Halogen-Free

We care. In our continuous efforts to better serve our customers and partners, we offer environmentally friendly products, use environmentally conscious processes and are fully committed to avoiding any banned materials in our products and processes. As you are ready to implement Lead-Free and Halogen-Free solutions, Numonyx is ready to deliver.

To develop these environmentally-friendly solutions Numonyx strongly collaborates with a large supplier base. Our suppliers routinely provide compliance certificates for homogeneous materials used in packaging: molding compounds, adhesives, films, lead frames, substrates, etc..

RoHS compliancy
For the Restriction of Hazardous Substances, the directive 2002/95/EC of the European Parliament is applicable since July 1, 2006. The aim of this directive is to ban heavy metals (Lead, Mercury, Cadmium, Hexavalent Chromium) and two brominated compounds: PolyBrominated Biphenyls (PBB) and PolyBrominated Diphenyl Ethers (PBDE). Exemptions are allowed when a RoHS compliant technical alternative is not available.

A maximum concentration value of 0.1% by weight (0.01% for Cd) in homogeneous materials (a material that cannot be mechanically disjointed into different materials) for each substance is tolerated. However, such substances are not intentionally added on Numonyx RoHS compliant products.

Currently, all non-custom products are engineered as RoHS Compliant. We work with our customers closely to enable their readiness for RoHS compliant products. All RoHS compliant parts have new part numbers (contact your field sales representatives for new part numbers) and are marked with a Pb-free symbol in accordance with J-STD-609 standards. The bar code label will state “PB-FREE” or “2nd LEVEL INTERCONNECT = ex”.

Pb-Free Symbol Key

  • e1 -- SnAgCu
  • e2 -- Sn alloys with no Bi or Zn (excluding SnAgCu)
  • e3 -- Sn
  • e4 -- Precious metals (e.g. Ag, Au, NiPd, NiPdAu) (no Sn)
  • e5 -- SnZn, SnZnX (all other Tin Zinc or Tin Zinc with tertiary alloys not containing Bi)
  • e6 -- Contains Bi
  • e7 -- Low temperature solder (≤ 150 ºC) containing Indium (no Bi)

The Numonyx Certificates of RoHS Compliance:

*China RoHS compliancy: Today the China RoHS requires only the disclosure of the same six EU RoHS hazardous substances, with the same maximum allowed concentrations. No exemptions are allowed. While China RoHS does not require removal of the hazardous substances, if the product contains one of the six substances, it does require: 1) Calculation of the Environmentally Friendly Use Period; 2) A table in the user’s guide disclosing the locations of any hazardous substances that are above the limits for the Maximum Concentration Values. As Numonyx already complies with the many rules and directives, only two options may be possible: with or without Lead (Pb). Currently: 1) All the EU RoHS compliant packages (with the exception of few Compact Flash Cards) are China RoHS compliant; 2) All new packaged products are engineered as China ROHS Compliant.  Please contact your sales representative if you need further details.

 

Halogen-Free
Numonyx works to realize Halogen-Free conversion with all customers. Halogen-Free is our standard offering today for new packages.

Halogens are mainly used as flame retardants. The current market trend is to ban halogens because it potentially generates dioxin when burned after disposal - causing health problems.


Currently, there is not a common definition of what the term “halogen-free” means. Numonyx defines a product halogen-free when the sum total of Chlorine and Bromine content in an organic homogeneous material is less then 900 parts per million (ppm). With this definition Numonyx meets the requirement levels for most of our customers. In addition, when a product is halogen-free, there is no antimony oxide (normally used as synergist for the flame retardant effect). The total content of antimony on halogen-free organic material is warranted to be less that 500 ppm.

Material Declaration Forms
Numonyx material declarations are based on our best knowledge of the materials and law. We have implemented all procedures necessary to ensure that banned substances are not used in specified materials. However, due to the different environmental and reliability requirements for packages and different technical requirements of processes, material formulations may vary considerably and are often proprietary formulations protected by patents.
 
Material declaration forms (MDF) provide the best information available for each package type. See our MDF package table. For MDFs for other package types, or for other materials documents (ICP, MSDS, etc) please contact Marilena.Sottile@numonyx.com. Please include the product name and your name, title and company name.

Rules and Directives
According to Numonyx policy, we are in compliance with the directives and all recently published laws and regulations regarding material declarations and elimination of chemical and hazardous substances from manufacturing processes and products. And, this has been accomplished without affecting our products’ reliability performance. Our policy is also to promptly inform all our customers and partners, through normal change control processes, of any possible change that could impact products.

In general such banned substances meet one of the following criteria:
• Substances banned by regulation
• Substances that will be prohibited or restricted in enforcement of the REACH Regulation (Registration, Evaluation, Authorization and restriction of CHemical substances)
• Substances with CMR (Carcinogenic, Mutagenic, Toxic to Reproduction) properties, as classified so by EU-D 67/548/EEC or IARC
• Relevant Risk phrases of EU-D 67/548/EEC : R39, R40, R45, R49 (Carcinogenic); R46, R68 (Mutagenic); R60, R61, R62, R63 (toxic to Reproduction)
• Substances with a high PBT (Persistent, Bio-accumulative, Toxic) potential, classified R50/53 by EU-D 67/548/EEC
• Substances classified as Ozone Depleting by Montreal Protocol, especially those classified R59 by EU-D 67/548/EEC
Regulation 1907/2006/EC and specified in its annex XVII
• Severe explosive substances classified R1, R3 or R4 by EU-D 67/548/EEC
• Substances classified R64 by EU-D 67/548/EEC (May cause harm to breastfed babies)
Exemptions could be allowed if a technical alternative is not available, and only if according to law.

The ban is intended on the final homogeneous material put into the marketplace. The raw materials may be subjected to chemical reactions during the manufacturing process, changing its categorization as a banned material. Please contact your sales representative if you need further details.
