EUROPEAN UNION RoHS EXEMPTION REVIEW CASE STUDYAuthors: Marie Cole, et al.
Company: IBM Corporation
Date Published: 10/4/2009 Conference: SMTA International
During the exemption review, representatives of individual companies and those affiliated with industry associations presented the technical progress applicable to approximately 30 exemptions and submitted position statements for review by a consultant selected by the European Commission. This paper will share a case study of activities undertaken to develop and submit a position on the exemption allowing the use of lead in solders for servers, storage and storage array systems, network infrastructure and similar equipment, exemption 7b. It will also provide some brief highlights of the exemption reviews of the ‘lead used in compliant pin connector systems' and the ‘lead in solders for flip chip packages' exemptions, also critical to high reliability server systems.
In addition, the paper will present an exemption transition strategy that could be applied to the phase out of any exemption. With technical advances in many areas of materials development and the goal of the European Commission to reduce the scope and number of exemptions, it can be expected that the electronics industry will face several years of change management as RoHS materials allowed today by an exemption are replaced. Developing a transition roadmap throughout the supply chain and maintaining an accurate materials content database to document compliance are an essential but complex task given the scope of expected modifications. This complexity is multiplied by the many other worldwide regulatory initiatives affecting hardware and environmental compliance material tracking needs.
Learning from this exemption review should be applied now to assure adequate industry preparations for the next review, even while the industry transitions away from several exemptions slated for near-in expiration.
