Download or read book Integrated Automotive High Power LED Lighting Systems in 3D MID Technology written by Werner Thomas and published by Cuvillier Verlag. This book was released on 2014-02-18 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growing energy consumption of lighting as well as rising luminous efficacies and -fluxes of high-power Light Emitting Diodes (LEDs) have contributed to the widespread use of LEDs in modern lighting systems. One of the most prominent users of the LED-technology is automotive (exterior) lighting. It benefits from LEDs’ high efficiencies and long lifetimes, but furthermore uses their small size as key feature to obtain new degrees of freedom in placing light elements. Although automotive LED-lighting is at the leading edge regarding 3D LED-lighting systems, their current construction is not optimised towards complex design requirements. This thesis deals with decreasing the complexity and improving the degrees of freedom in the design of three-dimensional high-power LED-lighting systems with power electronic LED-driver by enhancing the level of function integration. Three main challenges are identified for the proposed concept and are investigated throughout the thesis. These are the integration of the power electronic LED-driver, of spatial - and electrical-functions as well as of thermal management functions into the three-dimensional multifunctional component.

Download or read book Modeling and Simulation for Microelectronic Packaging Assembly written by Shen Liu and published by John Wiley & Sons. This book was released on 2011-08-24 with total page 586 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although there is increasing need for modeling and simulation in the IC package design phase, most assembly processes and various reliability tests are still based on the time consuming "test and try out" method to obtain the best solution. Modeling and simulation can easily ensure virtual Design of Experiments (DoE) to achieve the optimal solution. This has greatly reduced the cost and production time, especially for new product development. Using modeling and simulation will become increasingly necessary for future advances in 3D package development. In this book, Liu and Liu allow people in the area to learn the basic and advanced modeling and simulation skills to help solve problems they encounter. Models and simulates numerous processes in manufacturing, reliability and testing for the first time Provides the skills necessary for virtual prototyping and virtual reliability qualification and testing Demonstrates concurrent engineering and co-design approaches for advanced engineering design of microelectronic products Covers packaging and assembly for typical ICs, optoelectronics, MEMS, 2D/3D SiP, and nano interconnects Appendix and color images available for download from the book's companion website Liu and Liu have optimized the book for practicing engineers, researchers, and post-graduates in microelectronic packaging and interconnection design, assembly manufacturing, electronic reliability/quality, and semiconductor materials.
