Veritas et Visus Display Standard February 2009 IPC Symposium on Electronics and the Environment July 16-17, 2008, Cambridge, Massachusetts In this third report of three, Phillip Hill covers presentations from Benchmark Electronics, University of Massachusetts, and Intel EMS Viewpoint – Green Initiatives Aimee Siegler, Benchmark Electronics, Angleton, Texas In a brief presentation, Siegler gave an overview of the company’s activities – electronics manufacturing services (EMS). These are in medical, high-end computing, industrial controls; test & measurement; telecommunications; and military/aerospace. Benchmark Electronics is in the business of manufacturing electronics and providing services to OEMs of telecommunication equipment, computers and related products for business enterprises, video/audio/entertainment products, industrial control equipment, testing and instrumentation products and medical devices. The company provides specialized engineering services including product design, printed circuit board layout, prototyping and test development. Specifically the company specializes in device monitors and programmers; pumps and infusion technologies; glucose monitoring systems; servers and server products; high reliability computers; thermostats and ignition controls; HVAC control systems; optical recognition systems; incircuit test platforms; telecom test equipment; routers and switches; wireless radio base stations; optical networking; guidance systems; communication & control; and ID systems. Each customer has a different definition of green, Siegler said. We must be flexible to meet customer needs. Some customers didn’t know that they needed to start (RoHS, now REACH), let alone where to start. Dealing with the technical issues sometimes means that you have to share information with your competitors, Siegler pointed out. There are many different drivers to new legislation and regulations, both political and NGO driven. Social responsibility is here to stay – ISO is drafting a social responsibility guideline, to be released in 2010. Focus will be on: the environment; human rights and labor practices; organizational governance and fair operating practices; consumer issues and community involvement/society development. Environmental sustainability is not optional – the electronics industry can make a difference, Siegler concluded. Barriers and Opportunities for Advancing Design for Environment and Green Chemistry in Industry Joel A. Tickner, University of Massachusetts, Lowell, Massachusetts In a preliminary overview, Tickner said that there was a strong interest in many sectors in advancing green chemistry and design for the environment (DfE). There are many drivers for change, yet many barriers to change need to be overcome. There are great opportunities to move forward towards safer, more sustainable chemistries and products. The cultural change of REACH implies that no data = no market. There is a responsibility on companies to develop safety data, define safe uses of chemicals, and communicate with supply chains. There is a responsibility on manufacturers/importers to ask for permission (authorization) to use chemicals of very high concern. This means greater sharing of information on substances in products (preparations and articles) and a greater supply chain dialogue and forced cooperation on testing. 86
Veritas et Visus Display Standard February 2009 Technical barriers exist that can compromise product performance with a risk of lower performance. Often alternatives just don’t exist or are difficult to implement or are too costly in a short-term perspective. Government programs supporting DfE and green chemistry are inadequately resourced. There are limited programs to distinguish safer products and preferable treatment (what is safer?). There is little economic incentive to switch. Firms lack tools, data, support to move towards safer materials (toxicity, materials tracking, design, etc.). Often there is a lack of good communication up and down supply chains. Consumers, purchasers, and manufacturers are often not informed about safer options. Most chemicals in commerce lack some basic toxicity information. The situation is improving for high production volume chemicals and the new EPA CHAMP Program. REACH will solve some of the data gap problems. Large quantity users can make demands from suppliers (harder for smaller quantity ones), but smaller quantity users can use a series of tools. We don’t need perfect data, just enough to make informed decisions and to understand hazards, exposures, and potential trade-offs, Tickner said. Green chemistry is the utilization of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green chemistry is a revolutionary philosophy that seeks to unite government, academic and industrial communities by focusing on environmental impacts at the earliest stage of innovation and invention. This approach requires an open and interdisciplinary view of materials design, applying the principle that it is better to not generate waste in the first place, rather than disposing or treating it afterwards. It is better to prevent waste than to treat or clean up waste after it is formed, Tickner pointed out. He concluded by saying that the innovators and leaders will be the companies that recognize the changing drivers and emerging patterns and embrace changes in product design and chemicals management that go beyond the next set of regulations. They will be those who do not only respond to legal demands but foresee market, scientific, and political signals and think long term. “These are great opportunities for the electronics sector to take leadership in this area.” iNEMI BFR-Free PCB Material Evaluation Project Stephen Tisdale, Intel Corporation, Chandler, Arizona Barriers to green chemistry and DfE innovations The overall project objectives are to build on industry knowledge and capability; consider unique market segment requirements; identify technology readiness and gaps; stimulate supply capability; and recommend standards development opportunities. The anticipated outcomes are: define electrical requirements based on market segment application; validate electrical and mechanical properties – loss tangent and Dk modeling over required range of signal speed, and mechanical performance validation for lead free assembly; validate material supplier and PCB manufacturer infrastructure capability; and estimate costs – volume market leader for new material may not achieve cost parity with best-in-class. Tisdale then outlined what the project is and what it is not (see table on the next page). 87
