11、FRs, CFRs, and PVC are used in electronic or electrical products 7 B Suggested test protocols low-halogen process flow 8 C Clarification for including only Bromine however, this document will use the term “low-halogen” to refer only to bromine and chlorine to be consistent with the International Ele
12、ctrotechnical Commission (IEC) and IPC definitions of “halogen-free” (see 2.4). Refer to Annex C for further explanation for exclusion of astatine, iodine and fluorine. In this document, the term “low-halogen” is used to identify a material that contains low concentrations of bromine and chlorine fr
13、om brominated and chlorinated flame retardants (BFRs, CFRs) and polyvinyl chloride (PVC). Joint JEDEC/ECA Standard No. 709C Page 1 DEFINITION OF “LOW-HALOGEN” FOR ELECTRONIC PRODUCTS (From JEDEC Board Ballot JCB-18-03, formulated under the cognizance of the JEDEC JC-14.4 Subcommittee on Quality Proc
14、esses and Methods and the ECA S-1 Passive Components Steering Committee.) 1 Scope This standard provides terms and definitions for “low-halogen” electronic products that have the potential to contain the halogens bromine (Br) and chlorine (Cl) from the use of BFRs, CFRs, and PVC, and recommends meth
15、ods for marking and labeling. This standard may be applied to all nonmetallic and nonceramic materials within electronic products including, but not limited to, materials in the following components commonly found in electronic products: 1. Transistors, integrated circuits, modules consisting mainly
16、 of integrated circuits (e.g., multichip, hybrid), and memory modules 2. Resistors, capacitors, relays, inductors, and connectors 3. Printed circuit board assemblies (PCBAs) including components 4. Plastic in cables, sockets, switches and external wiring 5. Mechanical plastics (enclosures, fans, etc
17、.) 6. Films, tapes, inks, and adhesives 7. Soldering flux residues (when present) 8. Sound, shock, and vibration dampeners (foams, resins, etc.) This document establishes the maximum concentration level for the halogens bromine (Br) and chlorine (Cl) from the use of BFRs, CFRs, and PVC. While the ha
18、logen group contains fluorine, chlorine, bromine, iodine, and astatine, this document will use the term “low-halogen” to refer only to bromine and chlorine. Refer to Annex C for further explanation for exclusion of astatine, iodine and fluorine. NOTE The definition of “low-halogen” is different from
19、 the term “halogen-free” as described in IEC 61249-2 sectional standard related to non-halogenated base material and as defined in the J-STD-609A marking and labeling standard; standards that pertain only to printed boards and are currently in use in the electronics and solid-state industries. BFRs,
20、 CFRs, and PVC in materials that may be used during processing, in product delivery systems, or in packaging, but do not remain within the final product are not included in the scope of this document.

31、 (contd) block polymer: A substance composed of block macromolecules (IUPAC definition) brominated/chlorinated flame retardants (BFR/CFR): Flame retardants that contain bromine and/or chlorine. NOTE These compounds are typically added to or reacted into polymers such as certain epoxy resins and ther
32、moplastics to reduce their flammability. Examples include, but are not limited to, tetrabromobisphenol-A (TBBPA), brominated epoxy resins, and polybrominated diphenyl ethers (PBDEs). congener (within the context of this standard): A member of the same kind, class or group of compounds with similar s
33、tructures and similar chemical properties. copolymer: A polymer derived from more than one species of monomer. (IUPAC definition) electronic device: A device whose operation depends on the conduction of electrons and/or holes in vacuum, gas, or semiconductor. NOTE Examples of electronic devices incl
34、ude transistors, integrated circuits, hybrid integrated circuits, and modules containing active electronic components. electronic product: An item containing one or more electronic devices performing major functions. low-halogen: Meeting the criteria established in clause 4 of this document. NOTE Lo
35、w-halogen electronic products may still contain some halogens, providing, of course, that each material in them meets the requirements in clause 4. plastic: Any of a group of synthetic or natural organic compounds produced by polymerization, optionally combined with additives (organic or inorganic f
36、illers, modifiers, etc.) into a homogeneous material capable of being molded, extruded, or cast into various shapes and films. polymer alloy: A polymer blend (considered to be an alloy) that contains either a crystallizable component or two relatively rigid or amorphous polymers Joint JEDEC/ECA Stan
37、dard No. 709C Page 5 4 Requirements for low-halogen electronic products The halogens fluorine (F), iodine (I), and astatine (At) are not covered by this document (see annex C). Bromine (Br) and chlorine (Cl) refer to all oxidation states of these elements. Bromine (Br) and chlorine (Cl) in materials
38、 that may be used during processing but do not remain within the final product are not included in this definition. For an electronic product to be defined as “low-halogen”, each material within the product must meet all of the following requirements. 1) Each material within an electronic product, (
39、excluding printed board laminates) shall contain 1000 ppm (0.1%) by weight of bromine if the bromine source is from BFRs and 1000 ppm (0.1%) by weight of chlorine if the chlorine source is from CFRs, PVC, PVC congeners, PVC block polymers, PVC copolymers, or polymer alloys containing PVC. Higher con
40、centrations of bromine and chlorine are allowed in plastics contained within electronic products (other than printed board laminates contained within those devices) as long as their sources are not flame retardants, PVC, PVC congeners, PVC block polymers, PVC copolymers, or polymer alloys containing
41、 PVC. 2) All printed board laminates contained within electronic and electrical products, including those within a passive or solid-state device shall meet the “halogen-free” requirements for Br and Cl as defined in the most current version of one of the following specifications: IEC 61249-2, IPC-41
42、01, JPCA-ES-01. NOTE See Annex A for a list of likely uses of flame retardants, PVC, PVC congeners, PVC block polymers, PVC copolymers, or polymer alloys containing PVC within electronic products. 5 Compliance process for low-halogen electronic materials and components An electronic product often co
43、ntains many materials / components from a complex and global supply chain. Therefore, all individual entities or suppliers within the chain have to be required to take responsibility for ensuring that the materials / components that they supply meet this standards requirements. Each supplier / indiv
44、idual entity within the supply chain is only responsible to prove compliance to their respective customer for the material / component that they supply. Any material / component that is declared to be “low-halogen” per Clause 4 herein must be supported by proof that substantiates the claim. Since th
45、ere is not a single, simple, cost-effective, and reliable test method that covers the spectrum of materials / components included in electronic products, customers and suppliers should mutually agree on the best method to demonstrate compliance to this document. If analytical testing is used, elemen
46、tal Br and Cl analysis is the most expedient and cost effective to perform. (IEC 62321 provides screening and analytical test methods for some but not all of the substances within the scope of this document.) If results detect Br or Cl above 1000ppm threshold, the supplier should determine if the so
47、urce of the Br or Cl is from flame retardants, PVC, PVC congeners, PVC block polymers, PVC copolymers, or polymer alloys containing PVC. The proof of compliance documents may include material declarations, datasheets and / or analytical data. Joint JEDEC/ECA Standard No. 709C Page 6 6 Marking and la
48、beling for “low-halogen” electronic products 6.1 Marking of printed boards If all materials used in the fabrication of a finished printed board laminate contained within a passive or solid-state device meet the requirements in 4, item 1, and if marking is required, the marking shall be in accordance
49、 with J-STD-609. 6.2 Marking of mechanical plastics Mechanical plastic parts contained within a passive or solid-state device may be marked / labeled in accordance with ISO 11469:2000. Compositions containing flame retardants may be marked per ISO 1043-4:1998. 6.3 Marking of passive and solid-state devices, cables, and other components of an electronic product Marking is not required on passive or solid-state devices to denote low-halogen status. As an alternative, a part numbering scheme may be
