Code: EP32 Contents of this page:Description DescriptionThe current efforts to eliminate CFCs in the defluxing of electronic circuit boards have resulted in a need for effective alternatives. Aqueous cleaning systems has become a leading choice for this replacement. The use of water to clean, rather than solvents, can bring advantages in the areas of cleaning, worker safety and the environment. Circuit assembly manufacturers have generally been comfortable with solvent cleaning, because this method is effective and they have not had to be concerned with issues such as metal corrosion or waste water treatment. Although aqueous cleaning has many advantages over solvent cleaning, conversion to this technology results in new problems with which the industry is unfamiliar. even those who have been using water to clean may not be getting the most out of their current system or be aware of recent important advances. Because of a generally limited knowledge base, choice of aqueous cleaning systems, optimisation, problem solving, worker safety issues, environmental concerns and bewildering legal restrictions cause needless frustration and worry. This book explores all aspects of aqueous cleaning including the chemistry of aqueous saponifiers, performance, equipment used, measurement, waste treatment needed, safety and environmental issues relating to the selection and effective use of aqueous cleaning systems to deflux and clean electronic circuit board assemblies. Its emphasis is on the practical, while giving a clear presentation of the underlying principles. Readers will be able to gauge their understanding of the key chapters by working through challenging problems taken from real life situations and then referring to the solutions given. This book covers current aqueous cleaning technology but suggests ways to plan for future developments when installing and starting up an aqueous cleaning process now. Insight is given as to where the industry, cleaning requirements and regulations are headed. About the AuthorsAnthony Winston (Tony), who received his Bachelor’s degree in chemistry at the University of Nottingham in England in 1966, has been involved in various facets of Research and Development for almost 30 years. Much of his career was spent at Church & Dwight Co., Inc., of Princeton, New Jersey, most recently in the position of Director of New Technology. During his 25 years at Church & Dwight, Mr Winston was involved in all aspects of research, product and process development of several successful industrial and consumer products. In 1971, his efforts as a chemist resulted in the launch of the first successful non-phosphate laundry detergent produced in the United States. More recently, Mr Winston has led the development of new aqueous industrial metal cleaning technology designed to provide safe environmental alternatives to the use of hazardous solvents. Together with the co-author, Dr Frank Cala, they developed the first inorganic aqueous saponifiers for cleaning and defluxing electronic circuit assemblies. These products are highly effective in removing fluxes, are much safer to work with than other alternative products and are environmentally benign. Mr Winston recently accepted a new position as Vice President of Technology and Clinical Research at Enamelon, Inc., of East Brunswick, New Jersey, where he is leading the development of promising new technology in the oral health care area. He is the author and co-author of about fifty United States Patents, the majority of which cover various novel cleaning compositions or related technology. He has authored and co-authored a number of technical papers and has also taught day courses on aqueous cleaning technology.
Frank Cala holds a PhD in physical chemistry, which he received from Rutgers University in the United States. His university based research was in the fields of thermodynamics, kinetics and photochemistry. He holds the position of Senior R&D Manager at Church & Dwight and is responsible for the technical development of industrial cleaners. He has been with Church & Dwight for 18 years and had previously been with Colgate Palmolive for 7 years. Dr Cala’s corporate experience includes 25 years of formulating both consumer products and industrial cleaners and in bringing these to market. For the past several years he has focused on cleaning agents for electronic assemblies and has been very active in this area. He is the author or co-author of many papers and patents on the subject of cleaning electronic assemblies. Dr Cala has chaired numerous technical sessions on cleaning electronic assemblies and has presented many papers in this area. He has taught full-day courses on cleaning at major electronics conferences in the USA. He is a member of the Board of Directors of the Alliance for Cleaning Technologies. Additionally, he is a member of the Test Method Validation Team (TMVT) for Phase 2 testing of electronic cleaning agents in the USA. Table of Contents
