Utilização das diretivas RoHS e WEEE para equipamentos eletromédicos fabricados no Brasil / Using of RoHS and WEEE directives for electromedical devices from Brazil manufacturesPidone, Leandro Augusto 15 June 2011 (has links)
Dentro das exigências restritivas visando à mitigação de danos ambientais, várias ações estão sendo tomadas em termos mundiais, destacando-se os países onde a mobilização social e tomadas de decisão são mais efetivas. Entre estas ações as diretivas RoHS e WEEE, ambas da comunidade européia, destacam-se como interessantes procedimentos que se somam para a prevenção do uso de substâncias tóxicas e redução de emissão ao meio ambiente de resíduos sólidos de eletrônicos após o uso. Atualmente, em termos mundiais, não se observa o uso de tais procedimentos no que tange aos equipamentos eletromédicos após o término de vida útil e descarte. Este trabalho faz um estudo de ambas diretivas utilizando-se um equipamento eletromédico de fabricação nacional, um eletroestimulador. O equipamento foi criteriosamente desmontado e seus componentes classificados com base em sua classe de material e composição química. Após a desmontar e catalogar os componentes quanto à classe de materiais e composição química, foram sugeridos alguns procedimentos. Para atender a diretiva RoHS, a substituição de metais pesados presentes na liga utilizada na soldagem dos componentes eletrônicos. Para atender a diretiva WEEE, o processamento de resíduo de placa de circuito impresso inertizado em vidro. Deste modo verifica-se que os procedimentos adotados para cumprir com as duas diretivas européias foram adequados para os equipamentos eletromédicos tanto de fabricação nacional como internacional. / Within the restrictive requirements aimed at mitigating environmental damage, several actions being taken globally, highlighting the countries where social mobilization and decision making are more effective. Among these actions the RoHS and WEEE, of the European community, stand out as interesting procedures that are in addition to preventing the use of toxic chemicals and reducing emissions to the environment of electronic waste after use. Today, in the world is unusually such procedures with respect to electrical equipment after the end of useful life and its disposal. This work is a study of both using an electromedical equipment manufactured in Brazil, an electrostimutator. The equipment was carefully dismantled and its components classified based on their specific device and chemical composition. After removing and cataloging the components of the different kind of materials and chemical composition, suggested some procedures. To meet the RoHS directive, the replacement of nocive metals in the alloy used in soldering of electronic components. To meet the WEEE directive, the processing of waste printed circuit board inerted glass. Thus it appears that the procedures adopted to comply with two European directives were adequate for the electrical equipment manufacturing both domestically and internationally.

Adaptation of eco-design methods for SMEs in India : Experiences from the electronics industryLind, Sofia January 2007 (has links)
<p>This thesis presents guidelines for how eco-design methods can be adapted to facilitate the introduction of ecologically responsible manufacturing in small and medium sized enterprises (SMEs) in the Indian electronics industry. It also investigates the major opportunities and obstacles for eco-design to become a natural part of product design. This is urgent both from environmental and economic perspectives since the SMEs pollute a lot in proportion to their share of the total industrial production, and at the same time they are vulnerable for the increasing environmental demands on product design. The European Union recently introduced their directive on the Restriction of the Use of certain Hazardous Substances in Electrical and Electronic Equipment (RoHS) which bans certain hazardous chemicals in electric and electronic device. For many producers that supply to the European market this was a wake up clock to start thinking about environmental aspects related to production.</p><p>The study was carried out as an interview and questionnaire study at three SMEs in the electronics industry. Additional interviews were held with informants in different organisations. It was concluded that for SMEs in the Indian electronics industry qualitative and semi-quantitative eco-design methods should be chosen before quantitative methods. Eco-design methods should resemble traditional methods that are already used in the companies. For the product developers to be able to work with eco-design more education and other solutions are needed to raise the environmental knowledge. Support and commitment from top management is also imperative. Methods should be developed to encourage the establishment of multi functional teams and early integration of environmental aspects in design projects.</p><p>The external demands on environmentally responsible manufacturing are expected to increase in the future. This will most likely have a positive influence on the environmental awareness in the industry, just as the RoHS directive has had. However, there are still economic and technical barriers that need to be bridged for SMEs in India to be able to work with eco-design. More cooperation and communication between academics, policy makers and the industry is needed to make it happen.</p>

Lead-Free Solder Business Strategy - A case study for "A" company.Hsu, Chuang-Yao 11 August 2006 (has links)
Along with the increasing global environmental ism and the interest in green products, protecting the natural environment is essential to survival and economic development. The future marketing and promotion of products, in additional to the traditional variables of price and quality, requires consideration of a third variable - the environmental-friendly products. Many countries establish regulations to limit the application of ¡§lead¡¨ and other hazardous material. WEEE (Waste Electrical and Electronic Equipment) mandates recycling of electrical and electronic products. RoHS (Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment) restricts 6 controlled materials starting on 2006.07.01. The ¡§lead-free¡¨ trend had unprecedented impact in the field of electronics.
In the global industrial supply chain, Taiwan plays an important role in the manufacturing (OEM/ODM) stage. The Taiwan electronic industry¡¦s supply chain, in dealing with buyer¡¦s demands for green products have to take appropriate strategies to maintain the production competitive superiority of the global marketing.
Facing the coming of the green electronic era, this research, with the aim on the solder industry and its future economic development, studies how the industry could effectively use the available resources, analyzes the internal operations and the external factors. Using the case study for A company, what are the feasible business model can apply? This research is hopping to elevate Taiwan¡¦s international competitiveness in light of the green revolution in the electronic industry.

Previous issue date: 2008 / Resumo: Esse trabalho representa uma inovação na área de química analítica, abordando novas potencialidades da técnica de fluorescência de raios-X e utilizando o espalhamento da radiação como medida analítica e a quimiometria para tratamento dos dados. As potencialidades dessa técnica para análise das substâncias restritas pela Diretiva Européia 2002/95/EC ¿ RoHS foram avaliadas a partir de estudos realizados com um equipamento de EDXRF, equipado com um tubo de ródio como fonte de raios-X. As amostras analisadas eram soluções contendo cinco diferentes elementos (cádmio, chumbo, mercúrio, bromo e cromo). Além de adequado, o método proposto mostrou-se bastante rápido, simples e eficaz, bem como não destrutivo e de baixo custo, com grande potencial de substituir de forma eficiente as três técnicas analíticas usadas tradicionalmente. Os modelos de calibração apresentaram bons coeficientes de regressão (> 0,99), baixos valores de erros de previsão para amostras externas (< 15%, exceto para especiação de cromo) e limites de detecção e quantificação abaixo dos limites de controle definidos pela norma. Com esse mesmo método também foi possível a especiação direta de cromo utilizando um aparelho de raios-X convencional, fato inédito na literatura científica. Nesse caso os modelos de calibração também apresentaram bons coeficientes de regressão (> 0,97) e baixos valores de erros de previsão para amostras externas (< 10%) / Abstract: This work represents an innovation in analytical chemistry, dealing with new potentialities of X-ray fluorescence technique and using X-ray scattering effects and chemometrics for processing the data. The potential of this technique to analyze the restricted substances by European Directive RoHS/2002/95/EC were evaluated from studies with an EDXRF equipment, fitted with a rhodium tube as an X-ray source. The samples evaluated were solutions containing five different elements (cadmium, lead, mercury, bromine and chromium). Besides appropriate, the proposed method proved to be very fast, simple and effective, as well as not destructive and of low cost, with great potential to efficiently replace the three analytical techniques used traditionally. The calibration models present high values of regression coefficients (> 0,99), low values of prediction errors for external samples (< 15%, except for speciation of chromium) and limits of detection and quantification below the RoHS control limits. With this same method, it was possible the direct speciation of chromium using a conventional X-ray apparatus, an unprecedented fact in the scientific literature. In this case, the calibration models also present high values of regression coefficients (> 0,97) and low values of prediction errors for external samples (< 10%) / Mestrado / Quimica Analitica / Mestre em Química

Villkor för förändringsarbete : En studie av tre företags arbete vid implementering av RoHS-direktivet / Conditions for change. : A study of three businesses in the implementation of the RoHS directiveBerglund, Kerstin January 2009 (has links)
<p>Företag kan behöva förändra sitt sätt att arbeta av flera olika skäl. Marknaden ställer krav på billigare lösningar med bibehållen kvalitet. Myndigheter ställer krav på större miljöhänsyn. Syftet med den här uppsatsen är att granska tre olika företags förändringsarbete i samband med att RoHS-direktivet föreskrev att bly inte skall användas vid lödning. Ett företag har helt ställt om sin produktion, ett företag kör blandad produktion och ett av företagen endast en liten produktion med blyfritt eftersom dess kunder omfattas av de undantag som finns i direktivet. Undersökningen har utförts som kvalitativa intervjuer med miljö- och processansvariga på de olika företagen och visar att företagen haft olika strategier för att lyckas med omställningsarbetet. Mina huvudsakliga slutsatser är att förändringsarbetet påverkas av kontakter med olika nätverk samt möjligheten att praktiskt prova en ny process och i betydligt mindre utsträckning av formellt ledningsarbete såsom miljöledningssystem.</p>

The European Union WEEE and RoHS directives : How are Atlas Copco and CP’s handheld industrial tools and assembly systems affected by the WEEE and RoHS directives?Relkman, Anna January 2005 (has links)
<p>The European Union Member States has a common environmental policy. The intention of the environmental policy and the WEEE and RoHS directives are to preserve, protect and improve the quality of the environment, protect human health and make use of natural resources. The WEEE is abbreviation for “Waste Electrical and Electronic Equipment”. The WEEE directive purpose is to improve the reuse, recycling and recovery in order to reduce the amount of disposal of equipment and the contents going to landfill. The RoHS directive is abbreviation for “Restriction of the use of certain Hazardous Substances in electrical and electronic equipment”. The six restricted substances are lead, cadmium, mercury, hexavalent chromium and two brominated flame-retardants; PPB and PBDE. The purpose of the RoHS directive is to approximate the laws of the European Member States on the restrictions of the use of hazardous substances in EEE, “Electrical and Electronic Equipment”. The common legislation is needed because the companies shall have the same terms of concerns.</p><p>The amount of EEE that the European Member States generate is growing rapidly and that is why a common waste management is needed. The content of hazardous components in EEE is a major concern during the waste management phase and recycling of WEEE. The landfills do not have the possibility to handle the upcoming volumes of waste and the rubbish incineration creates high levels of heavy-alloy metal in our surroundings. The WEEE and RoHS directives covers ten categories of EEE and the producer responsibility shall encourage the design and production of EEE, which take into full account and facilitate their repair, possible upgrading, disassembly, reuse and recycling.</p><p>The Commission has not drawn up distinct guidelines and boundaries for the EEE within some of the categories in the WEEE and RoHS directives. This makes it difficult for the producers of EEE to determine if their products are within the scope of the directives. The definition of “large-scale stationary industrial tools” is one of the most difficult definitions to interpret. This definition includes four points that the EEE shall comply with to be allowed as an exemption.</p><p>Atlas Copco and CP are two of the concerned companies that have products within the scope of the WEEE and RoHS directives. In the Atlas Copco group there are two divisions; Atlas Copco and CP. Atlas Copco and CP develop, manufacture and market industrial tools, compressed air equipment, construction and mining equipment and assembly systems. It is Atlas Copco and CP’s industrial tools and assembly systems, which are affected by the WEEE and RoHS directives. Due to this Atlas Copco and CP needs to decide which of their products that is within the scope of the directives. Some of their industrial tools and assembly systems are in the grey-area of the legislation. The purpose of this thesis is to interpret the WEEE and RoHS directives and review Atlas Copco and CP’s industrial tools and assembly systems. The author believes that the majority of Atlas Copco and CP’s industrial tools and assembly systems are not “large-scale stationary industrial tools” because they sells as single units which the customers combine as they wish, to get the accurate performance. The tools are furthermore handhold and driven by electricity through a cable or battery and the industrial tools and assembly systems are not permanently fixed. The author’s decision which industrial tools and assembly systems are within the scope of the directives differentiates from Atlas Copco and CP’s decision.</p>

Implementation of Lead-Free Soldering in Highly Reliable ApplicationsBerglund, Ove January 2007 (has links)
<p>The directive of the European parliament and of the council on the Restriction of the use of certain Hazardous Substances (RoHS) in Electrical and Electronic Equipment (EEE) took effect in the European Union on July 1, 2006. Japan, California, China and Korea are all closed markets for exporters of components containing lead from July 1, 2007. Taiwan and Australia are working with similar directives. The RoHS directive is the reason why this thesis about the implementation of lead-free soldering in highly reliable applications is necessary.</p><p>The European Lead Free soldering NETwork (ELFNET) status survey from 2005 shows that the majority of the companies are well informed, but 20% are still not active in lead-free soldering. The Swedish industry is for the most part prepared and 95% of the components are lead-free. The transition to lead-free soldering will have a major affect on logistics and administration, because the RoHS directive is 90% about administration and logistics problems. Only 10% is technical problems.</p><p>The higher melting point in lead-free soldering affects every stage of the lead-free manufacturing, from assembly to testing and repair.</p><p>The major concern for highly reliable applications are that there are not enough data to understand to what grade lead-free solders will perform differently from lead based solders. Five different types of reliability testing were studied in this thesis; vibration, mechanical shock, thermal shock, thermal cycling and combined environments. Whiskers, voids, brittle fractures and mixed assembly problems were also studied. Individual tests alone should not be used to make definite decisions on lead-free soldering reliability. The lower reliability for lead-free solders in some tests does not necessarily mean that lead-free solders not can be used in highly reliable applications like defence electronics.</p><p>The most important conclusions from this thesis are:</p><p>• Update or change the logistic system and mark/label according to available standards.</p><p>• Secure a good board layout.</p><p>• Secure a good process control.</p><p>• Alternative surface board should be used. Tin-silver-copper (SAC) is the most reliable solder and Electroless Nickel/Immersion Gold (ENIG) is the most reliable surface finish.</p><p>• Remember that the higher temperature affects every stage of the manufacturing.</p><p>• No increased problems with whiskers or risk of high voiding levels.</p><p>• Mixed assembly is a risk. Compatibility and contamination risks must be taken seriously.</p><p>• Which environment will the applications be in? If it is not a highly vibrating and thermal cycling environment, lead-free soldering should be safe to use.</p> / <p>Europaparlamentets och rådets direktiv om begränsning av användningen av vissa farliga ämnen i elektriska och elektroniska produkter började gälla i Europeiska unionen 1 juli, 2006. Japan, Kalifornien, Kina och Korea är alla stängda marknader för exportörer av komponenter som innehåller bly från och med 1 juli, 2007. Taiwan och Australien arbetar med liknande direktiv. RoHS-direktivet är anledningen till varför detta examensarbete om implementeringen av blyfri lödning i högtillförlitliga applikationer är nödvändigt.</p><p>En undersökning från 2005 av ELFNET visar att majoriteten av företagen är väl informerade, men 20% är fortfarande i aktiva med blyfri lödning. Den svenska industrin är till största delen väl förberedd och 95% av komponenterna är blyfria. Övergången till blyfri lödning kommer att ha stor effekt på logistik och administration, därför att 90% är administrations- och logistikproblem i RoHS-direktivet. Bara 10% är tekniska problem.</p><p>Den högre smälttemperaturen i blyfri lödning påverkar varje steg av den blyfria tillverkningen, från montering till testning och reparation.</p><p>Den stora oron för högtillförlitliga applikationer är att det inte finns tillräckligt med data för att förstå i vilken grad som blyfria lod kommer att bete sig annorlunda jämfört med blybaserade lod. Fem olika typer av tillförlitlighetstester har undersökts i detta examensarbete; vibration, mekanisk chock, termisk chock, termisk cykling och kombinerade tester. Whiskers, voids, sprödbrott och blandad montering studerades också. Individuella tester ska inte användas för att ta några definitiva beslut om blyfri lödnings tillförlitlighet. Den lägre tillförlitligheten för blyfria lod i en del tester behöver nödvändigtvis inte betyda att blyfria lod inte kan användas i högtillförlitliga applikationer som försvarselektronik.</p><p>De viktigaste slutsatserna från detta examensarbete är:</p><p>• Uppdatera eller byt logistiskt system och märk enligt tillgängliga standarder.</p><p>• Säkerställ en bra kretskortsdesign.</p><p>• Säkerställ en bra processkontroll.</p><p>• Alternativa mönsterkort bör användas. SAC är det tillförlitligaste lodet och ENIG är den tillförlitligaste ytbehandlingen.</p><p>• Kom ihåg att den ökade temperaturen påverkar varje steg i tillverkningen.</p><p>• Inga ökade problem med whiskers eller stort antal voids.</p><p>• Blandmontage är riskfyllt. Kompatibilitet och risker med kontaminering måste tas på allvar.</p><p>• Vilken miljö kommer applikationen att befinna sig i? Är det inte en starkt vibrerande eller temperaturcyklisk miljö bör blyfri lödning vara säkert att använda.</p>
