Available in PDF, EPUB and Kindle. Book excerpt: Abstract: During ultrasonic welding of sheet metal, normal and shear forces act on the parts to be welded and the weld interface. These forces are a result of the ultrasonic vibrations of the tool, pressed onto the parts to be welded. Furthermore they determine the weld quality and the power that is needed to produce the weld. The main goal in this study is to measure and calculate the tangential forces that act on the parts and the weld interface during ultrasonic metal welding and correlate them to weld quality. In this study a mechanics based model was developed which included a model for the temperature generation during welding and its effect on the mechanical material properties. This model was then used to calculate the interface forces during welding. The model results were in good agreement with the experimental results, which included the measured shear force during welding. With the knowledge of the forces that act at the interface it might be possible to control weld quality (strength) and avoid sonotrode welding (sticking of the sonotrode to the parts). Without a solution to these two problems USMW will never be applicable to large scale automated production use, despite its advantages. In the experiments the influence of part dimensions, friction coefficient, normal force and vibration amplitude on weld quality and sonotrode adhesion were examined. The presented model is capable of predicting and explaining unfavorable welding conditions, therefore making it possible to predetermine weld locations on larger parts or what surface preparation of the parts to be welded would lead to an improved welding result. Furthermore shear force at the anvil measured during welding could be correlated to changing welding conditions. This is a new approach of explaining the process of USMW, because it is based on mechanical considerations. The use of a shear force measuring anvil has the potential to be implemented into welding systems and the shear force would provide an additional means of process control.

Available in PDF, EPUB and Kindle. Book excerpt: The fundamental mechanisms of ultrasonic welding and the application of this process to the joining of various heat-resistant materials were investigated. Previous studies which had shown the effects of time, temperature, and clamping force on ultrasonic welds were expanded to include studies of the shear force during welding. Ultrasonic spot welds made in various combinations of heat-resistant alloys generally confirmed the results of previous work with these alloys. Cracks were found at the edges of the spot welds in most of the material combinations studied. The effects of these cracks on weldment properties varied with the material. The presence of a reaction zone, apparently consisting of intermetallic compounds, was apparent in ultrasonic welds made between Ti and stainless steel. These findings indicate that ultrasonic welding is not suitable for the production of aircraft-quality spot welds in heat- resistant and dissimilar metal combinations. It is apparent as a material's hardness increases, and the ratio of tensile strength to yield strength decreases, that weldability by the ultrasonic process decreases.

This book was released on 2019-08-27 with total page 1079 pages. Available in PDF, EPUB and Kindle. Book excerpt: Packaging materials, assembly processes, and the detailed understanding of multilayer mechanics have enabled much of the progress in miniaturization, reliability, and functional density achieved by modern electronic, microelectronic, and nanoelectronic products. The design and manufacture of miniaturized packages, providing low-loss electrical and/or optical communication, while protecting the semiconductor chips from environmental stresses and internal power cycling, require a carefully balanced selection of packaging materials and processes. Due to the relative fragility of these semiconductor chips, as well as the underlying laminated substrates and the bridging interconnect, selection of the packaging materials and processes is inextricably bound with the mechanical behavior of the intimately packaged multilayer structures, in all phases of development for traditional, as well as emerging, electronic product categories.The Encyclopedia of Packaging Materials, Processes, and Mechanics, compiled in 8, multi-volume sets, provides comprehensive coverage of the configurations and techniques, assembly materials and processes, modeling and simulation tools, and experimental characterization and validation techniques for electronic packaging. Each of the volumes presents the accumulated wisdom and shared perspectives of leading researchers and practitioners in the packaging of electronic components. The Encyclopedia of Packaging Materials, Processes, and Mechanics will provide the novice and student with a complete reference for a quick ascent on the packaging 'learning curve,' the practitioner with a validated set of techniques and tools to face every challenge in packaging design and development, and researchers with a clear definition of the state-of-the-art and emerging needs to guide their future efforts. This encyclopedia will, thus, be of great interest to packaging engineers, electronic product development engineers, and product managers, as well as to researchers in the assembly and mechanical behavior of electronic and photonic components and systems. It will be most beneficial to undergraduate and graduate students studying materials, mechanical, electrical, and electronic engineering, with a strong interest in electronic packaging applications.

This book was released on 2013-12-11 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the third work in a series of monographs* written by a col lective group of authors and is devoted to the physical mechanisms of specific ultrasonic technological processes that have already come into general use, as well as those which have just begun to enjoy practical applications. The problems covered in the book are exceedingly important insofar as the understanding of the phys ical mechanisms of ultrasonic processes forms the solitary basis of an intelligent approach to the design of industrial equipment and proper choice of optimum working conditions. The purely em pirical approach to the solution of these problems does not afford satisfactory results, because the state of affairs in a high-inten sity acoustic field is complex and diversified. Many papers in the Soviet Union and abroad have been con cerned with the practical utilization of ultrasound, but the over whelming majority is limited to the solution of highly individual ized practical problems, usually under conditions that are not amenable to comparison. Systematic studies have been initiated in the Ultrasonics Section of the Acoustics Institute of the Academy of Sciences of the USSR on the physics of high-intensity ultrasonic waves and their effects on matter; the results of these studies form the basis of the present book.
