Vacuum Deposition onto Webs, Films and FoilsBy
- Charles Bishop, CAB Consulting, Ltd.
Roll-to-roll vacuum deposition is the technology that applies an even coating to a flexible material that can be held on a roll and provides a much faster and cheaper method of bulk coating than deposition onto single pieces or non-flexible surfaces, such as glass. This technology has been used in industrial-scale applications for some time, including a wide range of metalized packaging (e.g. snack packets). Its potential as a high-speed, scalable process has seen an increasing range of new products emerging that employ this cost-effective technology:
solar energy products are moving from rigid panels onto flexible substrates, which are cheaper and more versatile
in a similar way, electronic circuit boards can be produced on a flexible polymer, creating a new range of flexible electronics products
flexible displays are another area of new technology in vacuum coating, with flexible display panels and light sources emergingCharles Bishop has written this book to meet the need he identified, as a trainer and consultant to the vacuum coatings industry, for a non-mathematical guide to the technologies, equipment, processes and applications of vacuum deposition. His book is aimed at a wide audience of engineers, technicians and production management. It also provides a guide to the subject for sectors in which vacuum deposition is a novel technology, such as solar energy and flexible electronics. By taking a holistic end-to-end approach to vacuum deposition, from materials through processes to end-use, Bishop provides his readers with an invaluable set of analytical tools and rules-of-thumb that will enable them to
develop processes and products that reduce failure rates, increase system efficiency and improve end products improve the specification of system requirements
have more worthwhile discussions with engineering specialists and machinery suppliers.
