AMES LABORATORY SIGNS INTERNATIONAL LICENSING AGREEMENT ON LEAD-FREE SOLDER
AMES, Iowa -- A new lead-free solder alloy developed by scientists at the U.S. Department of Energy's (DOE) Ames Laboratory at Iowa State University (ISU) could soon become an integral component in electronics equipment sold worldwide.

Multicore Solders, a European-based company with a major manufacturing plant in Texas, has signed a licensing agreement to produce and market lead-free solder based on an Ames Laboratory patented composition. Multicore is a world leader in the development and manufacture of solder paste, wire and bars. The company's main customers are in the electronics industry, who use solder for joining processes in products such as cellular phones, televisions, VCRs and calculators, to name a few. Multicore also provides solder to the automotive industry for use on products such as electronic circuit boards for sensors and engine control computers.

"Multicore's strong technology base and marketing reach are the exciting things about this licensing agreement," says Iver Anderson, Ames Laboratory metallurgist and the leader of the team that developed the lead-free solder alloy. "The company has amazing access to the electronics solder market, which is a booming market at this time. They want to push worldwide acceptance of lead-free solder."

The lead-free solder developed by Anderson and a team of Ames Laboratory and Sandia National Laboratory scientists is made from an alloy of tin, silver and copper, and was developed partially in response to the growing trend to discontinue the use of tin-lead solder, which is currently the industry norm. The lead in tin-lead solder is toxic and poses a human health hazard.

Eliminating an environmental hazard is only one advantage of Ames Laboratory's new lead-free solder alloy. In addition, the alloy ingredients are widely available, the solder is easy to use, is stronger and stands up better in high-heat conditions, such as those found under the hood of an automobile. "It's going to be a more reliable solder than leaded solders, especially the tin-lead solder," says Anderson, who is currently working with Ford and General Motors in an industry/lab/university consortium to identify high-temperature solders for automotive applications.

"Multicore Solders is very impressed by Ames Laboratory's initiative in developing lead-free solder," says Gordon Arbib, chief executive of Multicore. "We look forward to the opportunity of introducing it through our worldwide manufacturing and sales organization."

The agreement with Multicore is the second licensing agreement to be signed for lead-free solder. The first agreement was signed in May 1995 with Johnson Manufacturing, an Iowa-based company that produces solder wire and ingots for industrial applications, such as compressors, heat exchangers and radiators. With Johnson Manufacturing servicing industrial needs and Multicore Solders marketing to the electronics industry, Anderson feels customers will have unlimited access to lead-free solder at any time. "In industry it's critical that there be more than one source for a product," says Anderson. "I feel this latest agreement helps form a strategic alliance critical to addressing the needs of industry."

Despite the success Anderson has had with tin-silver-copper-based solder, his efforts to continually improve lead-free solder have not slowed. Recent developments are currently in the process of being patented and will be part of the licensing agreements with Multicore Solders and Johnson Manufacturing.

Ames Laboratory is operated for the DOE by ISU. The Laboratory conducts research in various areas of national concern, including energy resources, high-speed computing design, and the study and synthesis of new materials.

Samsung Electronics: Samsung Electronics Develops Environmentally-Friendly Memory Module
M2 Communications (May 9, 2001)

* The company is working to eliminate the use of lead, chlorine, bromine, antimony and other substances that are harmful to the environment

* The new-concept module is to be used with all Samsung semiconductors from the second half of this year

SEOUL, Korea -- Samsung Electronics has completed development of a "green" semiconductor product that uses no halogen compound-which contain such toxic substances as lead, chlorine and bromine. Company officials say that the new-concept device will go into mass production in the second half of 2001.

Other companies have come out with semiconductors that use lead-free solder packages. However, Samsung is the first to develop a package and module that contains neither lead nor halogens.

The new concept is initially being applied to Samsung's 128Mb synchronous DRAM package and 256MByte module for PC-133 systems. Samsung's "green product" will satisfy the ever-stricter environmental protection regulations around the world. At the same time, the corporate image will be enhanced among environmentally-conscious consumers.

Samsung has replaced the tin-lead compound used to plate the package terminals with a tin-bismuth compound. The conventional tin-lead solder paste has also been replaced by a tin-silver-copper compound. Moreover, the external packages and printed circuit boards no longer contain halogens such as chlorine, bromine or antimony. Samples of the "green product" applied to conventional packages, BGA (Ball Grid Array) packages and memory modules have proven to be outstanding in terms of functionality, durability and environment friendliness. Samsung will proceed with plans to apply the concept to all its semiconductor products in the second half of this year.

The Samsung Group declared its commitment to protecting the environment in 1994, and since then Samsung Electronics has worked constantly to develop environmentally-friendly products. The "green product" is part of this concerted effort.

European Commission (EC)
As technical innovation and market expansion grow with rapid perpetuation, the growth of electronics in landfills is expected to grow at the same pace. Currently consumer electronics constitute 40% of lead in landfills, and in 1998 six million tons of waste from electronics was found in those landfills.

These volumes are expected to increase by at least three to five percent annually, which is three times higher than the growth of average municipal waste. Recognizing this, Member States within the European Commission took draft legislation to address these issues.

With that, the Waste Electrical and Electronic Equipment (WEEE) Directive was born. The main objectives of the Proposal have been:

Improved design of manufacturer's products to avoid generation of waste.

Manufacturers taking responsibility for certain phases of waste management.

Separate collections of electronics waste.

Appropriate systems established by manufacturers to improve treatment and reuse/recycling of electronics waste.

Because this is the only true legislation calling for the reduction in lead usage in PWBs, the industry has waited with bated breath for the release of each draft proposal. To the surprise of some, they were approached by a new draft proposal on Environment of Electrical and Electronic Equipment (EEE).
Are Two Head Better than One?
As the electronics industry eagerly awaited the release of the Official Proposal of the WEEE Directive, the European Commission showed it has another trick up its sleeve.

The recently formed DG-Enterprise, which replaced the DG-Industry, released a Draft Proposal of the Environment of Electrical and Electronic Equipment (EEE). Whereas the WEEE Directive calls for phase-outs of toxic materials, the EEE proposal calls for environmental and recycling compliance.

Some in the industry forecasted this in 1999, anticipating the demise of WEEE and it being replaced by two documents: one calling for the phase-outs, and the other requiring strict recycling measures. Whether this happens or not will be seen in the next release of the WEEE Proposal.

Commission Tackles Growing Problem of Electrical and Electronic Waste

Click here to download the Official Proposal of WEEE.

Brussels, 13 June 2000

The European Commission has adopted a proposal for a Directive on Waste Electrical and Electronic Equipment (WEEE) and a proposal for a Directive on the restriction of the use of certain hazardous substances in electrical and electronic equipment. The proposed Directives are designed to tackle the fast increasing waste stream of electrical and electronic equipment and complements European Union measures on landfill and incineration of waste. Increased recycling of electrical and electronic equipment, in accordance with the requirements of the proposal for a WEEE Directive, will limit the total quantity of waste going to final disposal Producers will be responsible for taking back and recycling electrical and electronic equipment. This will provide incentives to design electrical and electronic equipment in an environmentally more efficient way, which takes waste management aspects fully into account. Consumers will be able to return their equipment free of charge.

In order to prevent the generation of hazardous waste, the proposal for a Directive on the restriction of the use of certain hazardous substances requires the substitution of various heavy metals and brominated flame retardants in new electrical and electronic equipment from 1 January 2008 onwards.

Welcoming the adoption by the Commission of the draft Directive, Environment Commissioner Margot Wallström declared: "This is a major step towards the objective of sustainable production and consumption. I am pleased that the Commission has been able to agree on a balanced initiative, which the Environment, consumers and industry all stand to gain from". She added: "Due to the fast pace of technological innovation, electrical and electronic equipment constitute one of the fastest growing waste streams in the EU. It is therefore particularly important to implement the key principles of EU waste management policy, especially the prevention and the recycling of waste, in this area."

In order to reduce the amount of electrical and electronic waste disposed of in landfills and incinerators the proposed WEEE Directive seeks to establish separate collection and recycling systems for such waste. It also implements the principle of producer responsibility to provide incentives for producers to take into account, already at the product design stage, the need to reduce the use of hazardous substances and to improve the recyclability of these products.

The WEEE Directive, based on Article 175 of the Treaty, will address all electrical and electronic equipment used by consumers and currently not treated before going to incinerators or landfills(1). It also covers a wide range of professionally used electrical and electronic equipment, such as Information Technology (IT) and Telecommunication equipment, which is not sufficiently recycled today.

The waste stream of electrical and electronic equipment has been identified as one of the fastest growing waste streams in the European Union constituting 4% of the municipal waste today, increasing by 16-28% every five years - three times as fast as the growth of average municipal waste. Furthermore, it is one of the largest known sources of heavy metals and organic pollutants in the municipal waste. With a view to the resource intensive production of electrical and electronic equipment, the requirement to recycle these wastes will lead to significant resource savings. Thus, the new proposal fulfils a key objective of the Fifth Environmental Action Programme - the reduction in wasteful consumption of natural resources and the prevention of pollution.

The Directive on electronic waste complements EC legislation on waste disposal, including the Directives on landfills and incineration of waste, and follows the example set by other waste stream specific Directives, such as the recently adopted End-of-Life Vehicles Directive. Given that today more than 90% of electronic waste ends up in disposal or shredding facilities without any pre-treatment, depollution and proper recycling of this waste constitute the main

objectives of the proposal. Proper pre-treatment and recycling can, however, only be achieved through separate collection of electronic waste. Accordingly, Member States will have to organise this collection from private households. Producers will then take over the waste from designated collection facilities. From there the waste needs to be channelled to certified treatment facilities, where further treatment according to the standards set out in the Directive can be ensured. The treatment standards contain minimum percentages for the recovery of this waste. These would come into force no later than 2006, and would range between 60 and 80%, depending on the product category.

In line with the polluter pays principle producers need to organise and finance the treatment, recovery and disposal of waste. The entry into force of the financing obligation will be delayed by five years to minimise the impact on producers of the financing requirement regarding waste from products put on the market before entry into force of the legislation ("historical waste").

The proposed Directive on the restriction of the use of certain hazardous substances in electrical and electronic equipment, based on Article 95 of the Treaty, introduces a substitution requirement for those substances in electrical and electronic equipment, which pose the main environmental problems during disposal and recycling of such waste. This requirement will support ongoing efforts to substitute these substances by less harmful substances. In line with the Directive on End-of-Life Vehicles the targeted substances include the heavy metals, lead, mercury, cadmium and hexavalent chromium. In addition, two types of brominated flame retardants, PBB and PBDE, are required to be substituted by 1 January 2008. The substitution of PBB and PBDE must not lead to a lowering of the fire safety standards. Accordingly, the Directive provides for exemptions from the substitution requirement if such substitution is not possible.
