Restriction of Hazardous Substances Directive RoHS

The second possibility is the European waste legislation, which includes the Restriction of Hazardous Substances Directive (RoHS). The RoHS Directive is closely linked with the Waste Electrical and Electronic Equipment Directive (WEEE) which sets collection, recycling, and recovery targets for electrical goods and is part of a legislative initiative to solve the problem of toxic e-waste. 

The Restriction of Hazardous Substances Directive (RoHS) is the shortened form for Directive on the restriction of the use of certain hazardous substances in electrical and electronic equipment. It was adopted by the European Union in February 2003 [9]. In July 2006, the RoHS 1 directive took effect and was required to be enforced in each member state [10]. Each member state used the directive as a guide to establish its own enforcement and implementatiOTi policies. This directive restricts (with some exceptions) the use of certain hazardous materials in the manufacturing of various types of electronic and electrical equipment The hazardous materials include lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr polybrominated biphenyl (PBB), and polybrominated diphenyl ether (PBDE), [10]. 

The Restriction of Hazardous Substances Directive (RoHS) restricts (with some exceptions) the use of certain hazardous materials in the manufacturing of various types of electronic and electrical equipment. These hazardous materials include lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr " ), polybrominated biphenyl (PBB), and polybrominated diphenyl ether (PBDE). 

Under the early draft, EU countries shall ensure that the use of lead, mercury, cadmium, hexavalent chromium, PBB, and PBDEs (polybrominated biphenyls and polybrominated diphenyl ethers) in electrical and electronic equipment is substituted on 1 January 2008. These have now become the subject of the Restriction of Hazardous Substances directive (RoHS). Additionally the Commission was proposing that all plastics containing BFRs be separated out from electrical and electronic equipment before recycling or disposal. 

China, in addition to ratifying the Basel Convention, has a 2002 law banning hazardous waste imports. In 2005, the Management Measure for the Prevention of Pollution from Electronic Products became effective. It has been referred to as China s RoHS, specifying limits on materials similar to the EU Restriction of Hazardous Substances directive. A new waste disposal law enacted in 2009, Regulations for the Administration of the Recovery and Disposal of Electric and... 

In 2003, the European WEEE-Directive 2002/96/EG [5] was implemented to reduce the amount of electronic waste and foster reuse, recovery and recycling of electric and electronic equipment. Closely connected to this, the restriction of hazardous substances Directive 2002/95/EG [6] (RoHS) was adopted by the EC in 2003 with the aim to restrict the use of hazardous substances in the manufacture of electric and electronic products.

RoHS Since the Directive on the restriction of the use of certain hazardous substances in electrical and electronic eqnipment (cotmnonly referred to as the Restriction of Hazardous Substances directive of the RoHS directive) came into force in the European Union (EU) in Jnly 2006 [167]. Some of the same regulations on chemical management have been adopted in other parts of the world. The RoHS directive restricts the amount of PBBs and PBDEs [168] contained in electrical and electronic equipment to less than 1000 ppm. No electronic electric apparatus can be marketed in an EU member state if it contains those materials in excess of a designated value of RoHS. PBBs and PBDEs are among the large variety of brominated flame retardants (BFRs) used in plastics and textiles. PBBs are no longer produced, but PBDEs were in widespread nse before the RoHS directive came into effect, and...

In the case of green chemistry, and more especially chemical substitution, a number of policy instruments are relevant. The traditional approach is to ban certain toxic chemicals in order to induce substitution efforts. Such bans are usually preceded by examples of successful substitutions, as it is controversial to ban chemicals when no alternatives exist at reasonable cost. Otherwise, industry is often granted generous phase-in periods, in order to develop substitutes. A third way is to grant derogations when it is hard or very costly to develop substitutes. The latter approach has been applied in the context of the EU Restriction of Hazardous Substances (RoHS) Directive (Directive 2002/95/EC), which bans six substances in electrical and electronic products. A slightly less interventionist approach is to put restrictions on uses of certain chemicals. Other administrative approaches include the ban of chemicals, or restrictions in use, in individual operations when these apply for permits. 

For example, the electronics industry was adamant that the material phase-outs stipulated within the Restriction of Hazardous Substances (RoHS) Directive for new electrical and electronic equipment must apply equally across Europe. In a joint letter to the Commission sent by leading producers, they urged a clear legal basis for the RoHS directive, so as to provide a high level of protection for citizens without creating uncertainty for business and undermining the Single Market (EC, 2001). 

There is also the EU Restriction of the Use of Certain Hazardous Substance Directive (RoHS) in electrical and electronic equipment which bans new electrical and electronic equipment with more than agreed levels of cadmium, hexavalent chromium, lead, mercury, polybrominated biphenyls (PBB) and polybrominated diphenyl ether (PBDE) flame retardants, in the EU. The RoHS Directive and the UK-RoHS regulations came into force on 1st July 2006 [9]. To prevent the generation of hazardous waste, the Directive 2002/95/EC requires the substitution of all heavy metals (cadmimn, hexavalent chromium, lead and mercury) and brominated flame-retardants (PBB or PBDE) in new electrical and electronic equipment sold as of 1st July 2006 [10].

Banned or restricted substances include lead, mercury, cadmium, hexavalent chromium, certain brominated flame retardants (PBBs), and polybrominated diphenyl ethers (PBDEs). 

Recently, Pb-free piezoelectric materials have been researched because of the toxin of Pb for health. It was applied as restriction of hazardous substances (RoHs) from 1 July 2006 based on directive 2001/95/EC of the Europjean Parliament and of the Coimcil of 27 January 2003,... 

Over the last decade there have been a number of trends driving increased use of PAEK in new classes of electronics applications. The Waste Electrical and Electronic Equipment (WEEE) and Restriction of Hazardous Substances (RoHS) directives restrict the use of heavy... 

With the implementation of the European Union (EU) directive on Restriction of Hazardous Substances (RoHS), the printed circuit industry has been forced to undergo a revolution in technology that is unprecedented in its history.The result is commonly called lead-free, a term that the reader will find used throughout this book, even though the restrictions are on several materials in addition to lead, as described in Chapter 1. The reason for this emphasis is that the biggest impact on the industry is the elimination of lead in the solder that is used for interconnection of the components and the board. 

Directive 2002-95-EC of the European Parhament and of the Council 27 Jan 2003, which restricts the use of certain hazardous substances in electrical and electronic equipment.This directive is also known as RoHS (Restriction of Hazardous Substances). 

A new requirement on packages— that of lead-free solder—has initiated a tremendous amount of developmental effort in the past few years. This effort stems from the requirement of packages exported to the European Union (EU) market, to pass Restriction of Hazardous Substances (RoHS) compliance requirements set forth in the Directive 2002/95/EC of the... 

In addition, the advent of the European Union s Restriction of Hazardous Substances (RoHS) directive and the lead-free assembly processes that result are redefining the requirements for base materials. RoHS has a severe impact on all aspects of base materials technology. The impact of lead-free assembly on base materials and a method of selecting materials for lead-free assembly are discussed in Chaps. 10 and 11. Requirements to support circuit densification, reliability, and electrical performance are also critical and will be discussed in Chap. 9. This chapter discusses grades and specifications of base materials, as well as the manufacturing processes used to make them. 

Environmental legislation such as the European Union s Restriction of Hazardous Substances (RoHS) directive has a profound impact on all levels of the electronics supply chain, including these components. RoHS restricts the use of lead, which is an element in the solder used for component assembly onto printed circuits. The impact on the base materials and components is primarily the result of higher assembly temperatures that are associated with lead-free assembly. Table 7.1 summarizes the key issues for base material components. RoHS issues will be discussed further in Chap. 10. 

The Restriction of Hazardous Substances (RoHS) Directive 2002/95/EC places restrictions upon specific materials that may be included in PCB fabrication materials, including solder masks. These requirements may require some products to be reformulated. Some products and/or markets may require low-halogen materials to comply with company or industry specifications. Again, these requirements have required some solder masks to be reformulated or new products to be developed.

The use of chromate conversion coatings has led to progressively greater restrictions imposed by national and international legislation (European Union directive 2002/95/EC on the Restriction of Hazardous Substances (RoHS) and European Union directive 2002/96/EC on Waste Electrical and Electronic Equipment (WEEE)) relating to concerns over health, safety and environmental protection regarding the use of these treatments. However, the aeronautical industry is a major chromates consumer until a viable alternative can be found. 

In the early 1990s, legislation was proposed in the US, but no regulatory action was taken. The movement toward lead-free electronics emerged into concrete legislation in Europe on June 13, 2000 when the European Commission adopted two proposals A Directive on Waste of Electrical and Electronic Equipment (WEEE), and a Directive on the Restriction of Hazardous Substances (ROHS). The WEEE requires Member States to set up take-back centers for end-of-life recovery at no cost to the consumer. The initial WEEE included the ROHS requirements and...
