Description : With all the environmental concerns and constraints today and stricter future regulations, there is a patent need to replace materials noxious to the environment by environmentally-friendly alternatives. Electrically conductive adhesives (ECAs) are one such example. ECAs offer an excellent alternative to lead-solder interconnects for microelectronic packaging applications. ECAs are used in electronics for laptop computers, camcorders, watch electronics, hard-drive suspensions and a myriad of electronic equipments. Environmentally-friendly ECAs offer many advantages vis-à-vis solder, such as simple and low-temperature processing conditions, better thermo mechanical performance and finer pitch. This book is based on the two Special Issues of the Journal of Adhesion Science and Technology (JAST vol. 22, no. 8-9 and vol. 22, no. 14) dedicated to this topic. The book contains a total of 21 papers (reflecting overviews and original research) and is divided into three parts as follows: Part 1: Introduction and Recent Developments, Part 2: Mechanical, Durability and Reliability Aspects and Part 3: Characterization and Properties.
Description : “Electrical Conductive Adhesives with Nanotechnologies” begins with an overview of electronic packaging and discusses the various adhesives options currently available, including lead-free solder and ECAs (Electrically Conductive Adhesives). The material presented focuses on the three ECA categories specifically, Isotropically Conductive Adhesives (ICAs) Anisotropically Conductive Adhesives/Films (ACA/ACF) and Nonconductive Adhesives/Films (NCA/NCF). Discussing the advantages and limitations of each technique, and how each technique is currently applied. Lastly, a detailed presentation of how nano techniques can be applied to conductive adhesives is discussed, including recent research and development of nano component adhesives/nano component films, their electrical properties, thermal performance, bonding pressure and assembly and reliability.
Description : This reference provides a complete discussion of the conversion from standard lead-tin to lead-free solder microelectronic assemblies for low-end and high-end applications. Written by more than 45 world-class researchers and practitioners, the book discusses general reliability issues concerning microelectronic assemblies, as well as factors specif
Description : Covering a wide range of industrial applications across sectors including medical applications, automotive/aerospace, packaging, electronics, and consumer goods, this book provides a complete guide to the selection of adhesives, methods of use, industrial applications, and the fundamentals of adhesion. Dr Ebnesajjad examines the selection of adhesives and adhesion methods and challenges for all major groups of substrate including plastics (thermosets and thermoplastics), elastomers, metals, ceramics and composite materials. His practical guidance covers joint design and durability, application methods, test methods and troubleshooting techniques. The science and technology of adhesion, and the principles of adhesive bonding are explained in a way that enhances the reader's understanding of the fundamentals that underpin the successful use and design of adhesives. The third edition has been updated throughout to include recent developments in the industry, with new sections covering technological advances such as nanotechnology, micro adhesion systems, and the replacement of toxic chromate technology. Provides practitioners of adhesion technology with a complete guide to bonding materials successfully Covers the whole range of commonly used substrates including plastics, metals, elastomers and ceramics, explaining basic principles and describing common materials and application techniques Introduces the range of commercially available adhesives and the selection process alongside the science and technology of adhesion
Description : This Festschrift documents the Proceedings of the First International Congress on Adhesion Science and Technology, held in honor of Dr. Kash Mittal on the occasion of his 50 birthday, in Amsterdam, The Netherlands, October 16-20, 1995. It contains the full accounts of the plenary and invited lectures, which are divided into the following seven parts: Part 1: Fundamental aspects of adhesion and general topics; Part 2: Contact angle, wettability and surface energetics; Part 3: Surface modification: Relevance to adhesion; Part 4: Adhesives and adhesive joints; Part 5: Adhesion aspects of polymeric coatings, and polymer-polymer interphase; Part 6: Metal-polymer and metal-ceramic adhesion; and Part 7: General papers. The topics covered include many different aspects of adhesion science and technology, and both fundamental and applied issues are addressed. The final section of this volume gives a listing of titles, authors and affiliations of the other 185 papers which were included in the technical program of the conference.
Description : Adhesives have been used for thousands of years, but until 100 years ago, the vast majority was from natural products such as bones, skins, fish, milk, and plants. Since about 1900, adhesives based on synthetic polymers have been introduced, and today, there are many industrial uses of adhesives and sealants. It is difficult to imagine a product—in the home, in industry, in transportation, or anywhere else for that matter—that does not use adhesives or sealants in some manner. The Handbook of Adhesion Technology is intended to be the definitive reference in the field of adhesion. Essential information is provided for all those concerned with the adhesion phenomenon. Adhesion is a phenomenon of interest in diverse scientific disciplines and of importance in a wide range of technologies. Therefore, this handbook includes the background science (physics, chemistry and materials science), engineering aspects of adhesion and industry specific applications. It is arranged in a user-friendly format with ten main sections: theory of adhesion, surface treatments, adhesive and sealant materials, testing of adhesive properties, joint design, durability, manufacture, quality control, applications and emerging areas. Each section contains about five chapters written by internationally renowned authors who are authorities in their fields. This book is intended to be a reference for people needing a quick, but authoritative, description of topics in the field of adhesion and the practical use of adhesives and sealants. Scientists and engineers of many different backgrounds who need to have an understanding of various aspects of adhesion technology will find it highly valuable. These will include those working in research or design, as well as others involved with marketing services. Graduate students in materials, processes and manufacturing will also want to consult it.
Description : High performance polymers are extensively used in the fabrication, assembly and packaging of semiconductor components. The basic purpose of this book is to review the present status of the electrically conductive and thermally conductive adhesive technology, primarily for the well established die attach market, but also for the anisotropic adhesive films used to interconnect electronic drivers to liquid crystal display panels, and adhesives which are currently tested to replace soft solders in the surface mount technology. Contents: 1. Applications, market survey and standards. 2. Electrical and thermal conductivities. 3. Fillers and resins. 4. Properties of uncured adhesives. 5. Properties of cured adhesives. 6. Thermally-induced stresses. 7. Reliability concerns. 8. Current developments.
