The technology for preventing and mitigating contamination of electronic products is reviewed in four major ways: the types and sources of contaminants; typical contamination effects; contamination removal methods; and contamination prevention through design, process, product protection, and testing
Contamination problems have become a major factor in determining the manufacturability, quality, and reliability of electronic assemblies. Understanding the mechanics and chemistry of contamination has become necessary for improving quality and reliability and reducing costs of electronic assemblies. Designed as a practical guide, Contamination of
The papers included in this issue of ECS Transactions were originally presented in the symposium ¿Corrosion of Electronic and Magnetic Materials¿, held during the 216th meeting of The Electrochemical Society, in Vienna, Austria from October 4 to 9, 2009.
Electronic Waste Management and Treatment Technology applies the latest research for designing waste treatment and disposal strategies. Written for researchers who are exploring this emerging topic, the book begins with a short, but rigorous, discussion of electric waste management that outlines common hazardous materials. such as mercury, lead, silver and flame-retardants. The book also discusses the fate of metals contained in waste electrical and electronic equipment in municipal waste treatment. Materials and methods for the remediation, recycling and treatment of plastic waste collected from waste electrical and electronic equipment (WEEE) are also covered. Finally, the book covers the depollution benchmarks for capacitors, batteries and printed circuit boards from waste electrical and electronic equipment (WEEE) and the recovery of waste printed circuit boards through pyrometallurgy. - Describes depollution benchmarks for capacitors, batteries and printed wiring boards from waste electronics - Covers metals contained in waste electrical and electronic equipment in municipal waste - Provides tactics for the recycling of mixed plastic waste from electrical and electronic equipment
E-waste management is a serious challenge across developed, transition, and developing countries because of the consumer society and the globalization process. E-waste is a fast-growing waste stream which needs more attention of international organizations, governments, and local authorities in order to improve the current waste management practices. The book reveals the pollution side of this waste stream with critical implications on the environment and public health, and also it points out the resource side which must be further developed under the circular economy framework with respect to safety regulations. In this context, complicated patterns at the global scale emerge under legal and illegal e-waste trades. The linkages between developed and developing countries and key issues of e-waste management sector are further examined in the book.
"Electronic devices and circuits are employed by a range of industries in testing conditions from extremes of high- or low-temperature, in chemically corrosive environments, subject to shock and vibration or exposure to radiation. This book describes the diverse measures necessary to make electronics capable of coping with such situations as well as to gainfully exploit any new phenomena that take place only under these conditions."--Prové de l'editor.
Emerging Contaminants in the Environment: Challenges and Sustainable Practices covers all aspects of emerging contaminants in the environment, from basic understanding to different types of emerging contaminants and how these threaten organisms, their environmental fate studies, detection methods, and sustainable practices of dealing with contaminants. Emerging contaminant remediation is a pressing need due to the ever-increasing pollution in the environment, and it has gained a lot of scientific and public attention due to its high effectiveness and sustainability. The discussions in the book on the bioremediation of these contaminants are covered from the perspective of proven technologies and practices through case studies and real-world data. One of the main benefits of this book is that it summarizes future challenges and sustainable solutions. It can, therefore, become an effective guide to the elimination (through sustainable practices) of emerging contaminants. At the back of these explorations on sustainable bioremediation of emerging contaminants lies the set of 17 goals articulated by the United Nations in its 2030 Agenda for Sustainable Development, adopted by all its member states. This book provides academics, researchers, students, and practitioners interested in the detection and elimination of emerging contaminants from the environment, with the latest advances by leading experts in emerging contaminants the field of environmental sciences. - Covers most aspects of the most predominant emerging contaminants in the environment, including in soil, air, and water - Describes the occurrence of these contaminants, the problems they cause, and the sustainable practices to deal with the contaminants - Includes data from case studies to provide real-world examples of sustainable practices and emerging contaminant remediation
Examining numerous examples of highly sensitive products, this book reviews basic reliability mathematics, describes robust design practices, and discusses the process of selecting suppliers and components. He focuses on the specific issues of thermal management, electrostatic discharge, electromagnetic compatibility, printed wiring assembly, environmental stress testing, and failure analysis. The book presents methods for meeting the reliability goals established for the manufacture of electronic product hardware and addresses the development of reliable software. The appendix provides example guidelines for the derating of electrical and electromechanical components.
Unbridled urbanization and development of natural land resources has led to the degradation of our surrounding environment. The air that we breathe, the water we drink and the food we eat is at risk of being contaminated with a plethora of chemical pollutants, some of them being potentially carcinogenic. This presents a challenge to human health. This book attempts to address this challenge in two parts which represent two different approaches. The first part of the book summarizes the alarming effects of environmental contaminants. Various studies depicting the direct relationship of environmental contaminants with cancer incidence have been referenced. Scientific studies have established an inverse relation between cancer and ingestion of dietary phytoconstituents (phytochemicals) in the form of fruits, vegetables and botanical herbs. Plant products as dietary supplements can suppress contaminant toxicity by regulating the resulting reactive species and also by assisting their bodily excretion through Phase 1 and Phase 2 enzyme metabolism. The second part of the book, shifts focus to phytoconstituents which, if included in diet, can prevent the harmful effects of pollutants. The text references numerous studies showing the anti-mutagenic, anti-genotoxic and anti-carcinogenic potential of many plant products. The combination of information about contemporary issues of carcinogenic contaminants in the environment coupled with the references to relevant studies in this handbook will enlighten readers studying courses in environmental chemistry, toxicology, botany, and ecology about environmental toxins and help them understand specific dietary measures known to reduce the toxic impact. Researchers in the field of nutrition can also benefit from the information provided.
Applications, Processes, and Controls is the second volume in the Handbook for Critical Cleaning, Second Edition.Should you clean your product during manufacturing? If so, when and how? Cleaning is essential for proper performance, optimal quality, and increased sales. Inadequate cleaning of product elements can lead to catastrophic failure of the
