This book was released on 2017-09-19 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modeling and Design of Electromagnetic Compatibility for High-Speed Printed Circuit Boards and Packaging presents the electromagnetic modelling and design of three major electromagnetic compatibility (EMC) issues related to the high-speed printed circuit board (PCB) and electronic packages: signal integrity (SI), power integrity (PI), and electromagnetic interference (EMI). The emphasis is put on two essential passive components of PCBs and packages: the power distribution network and the signal distribution network. This book includes two parts. Part one talks about the field-circuit hybrid methods used for the EMC modeling, including the modal method, the integral equation method, the cylindrical wave expansion method and the de-embedding method. Part two illustrates EMC design methods and explores the applications of novel metamaterials and two-dimensional materials on traditional EMC problems. This book is designed to enhance worthwhile electromagnetic theory and mathematical methods for practical engineers and to train students with advanced EMC applications.

This book was released on 2013-06-29 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proper design of printed circuit boards can make the difference between a product passing emissions requirements during the first cycle or not. Traditional EMC design practices have been simply rule-based, that is, a list of rules-of-thumb are presented to the board designers to implement. When a particular rule-of-thumb is difficult to implement, it is often ignored. After the product is built, it will often fail emission requirements and various time consuming and costly add-ons are then required. Proper EMC design does not require advanced degrees from universities, nor does it require strenuous mathematics. It does require a basic understanding of the underlying principles of the potential causes of EMC emissions. With this basic understanding, circuit board designers can make trade-off decisions during the design phase to ensure optimum EMC design. Consideration of these potential sources will allow the design to pass the emissions requirements the first time in the test laboratory. A number of other books have been published on EMC. Most are general books on EMC and do not focus on printed circuit board is intended to help EMC engineers and design design. This book engineers understand the potential sources of emissions and how to reduce, control, or eliminate these sources. This book is intended to be a 'hands-on' book, that is, designers should be able to apply the concepts in this book directly to their designs in the real-world.

This book was released on 2015-04-16 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: The high reliability and operating speed (high clock frequencies) are essential elements for electronic equipment. With the increase in the speed of operation of the circuits on printed circuit boards (PCB), the wavelength becomes comparable to the length of interconnections. This implies in the circuit analysis being then made in terms of transmission line. From this fact, undesirable effects such as failure to signal integrity (SI) may occur, for example, the crosstalk noise. This problem of signal integrity can bring serious harm to the functioning of a printed circuit board. It is important that such failure is remediated in the initial phase of the project, since the correction becomes even simpler and less costly. In fact, some computational tricks were used to try to measure integrity issues of crosstalk-type signal, because without such tools, advanced calculations, which would cause delays in the process, would be needed.

Abstract: ABSTRACT The broad applications of power electronic equipment improve the power factor and efficiency of the power converters, but they also generate electromagnetic noise to pollute the environment and the power system network. The development of power filter technology provides an effective solution towards the power frequency harmonics. Through its research, this thesis contributes to the development of high frequency electromagnetic interference (EMI) in switch mode power supply (SMPS). Traditional EMI reduction technologies relies on filtering and shielding, which are generally applied to the product by simple design rules or integrated simulation software. The high voltage switching characteristics of the switch mode power supply and the near field electric coupling between the PCB traces have a significant impact on the final EMI emission of the product. A novel approach technique to reduce such the electric coupling is mandatory. This thesis describes the measurement method used to assess the electric field coupling and the level of significance. The measurement result confirms the contribution of the electric coupling in the overall EMI generated from the SMPS. Extensive experiments verify the effectiveness of EMI reduction techniques. A thorough analysis on the electric field models of the PCB traces concludes the capacitance effect determines a high portion of the EMI generated from the SMPS. Nevertheless, the calculation of capacitance is time consuming. Any alternation in the geometry of the circuit requires the whole system to be re-calculated the whole system. During the experimental stage, a de-coupled field calculation closely resembles the mythesis.doc - iii - capacitance. The index of the electric field coupling is then defined as the "Coupling Index." It comprises the benefits fast calculation and independence of the changes in the PCB geometry. Utilising the "Coupling Index," a computer simulation tool is developed to provide a quantitative comparison on the noise coupling as well as the EMI as a result of electric field coupling. On the whole, the simulation tool combined with artificial intelligence forms an integrated simulation software with automatic trace routing. The software optimises the effects of the electric field coupling between the PCB traces to reduce the EMI generation. In summary, this thesis demonstrates the EMI due to electric field coupling in SMPS and develops an automatic software package to reduce the coupling effect with the aid of artificial software. This contributes to the ultimate PCB auto-routing tools with all EMI parameters taken into consideration. mythesis.doc - iv - DOI: 10.5353/th_b2995770 Subjects: Electromagnetic interference Electronic circuits - Noise

This book was released on 2000-07-04 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Electromagnetic compatibility (EMC) is an engineering discipline often identified as "black magic." This belief exists because the fundamental mechanisms on how radio frequency (RF) energy is developed within a printed circuit board (PCB) is not well understood by practicing engineers. Rigorous mathematical analysis is not required to design a PCB. Using basic EMC theory and converting complex concepts into simple analogies helps engineers understand the mitigation process that deters EMC events from occurring. This user-friendly reference covers a broad spectrum of information never before published, and is as fluid and comprehensive as the first edition. The simplified approach to PCB design and layout is based on real-life experience, training, and knowledge. Printed Circuit Board Techniques for EMC Compliance, Second Edition will help prevent the emission or reception of unwanted RF energy generated by components and interconnects, thus achieving acceptable levels of EMC for electrical equipment. It prepares one for complying with stringent domestic and international regulatory requirements. Also, it teaches how to solve complex problems with a minimal amount of theory and math. Essential topics discussed include: * Introduction to EMC * Interconnects and I/O * PCB basics * Electrostatic discharge protection * Bypassing and decoupling * Backplanes-Ribbon Cables-Daughter Cards * Clock Circuits-Trace Routing-Terminations * Miscellaneous design techniques This rules-driven book-formatted for quick access and cross-reference-is ideal for electrical and EMC engineers, consultants, technicians, and PCB designers regardless of experience or educational background."

This book was released on 1990 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The finite element method is applied to compute the distributed capacitance and inductance matrices for multilayered dielectric, planar transmission media. The analysis involves the solution of the Laplace equation in two dimensions for multiconductor configurations in microstrip, triplate, or TEM Cell configurations of arbitrary cross section and utilizes a unique node allocation algorithm for automatic generation of the finite element mesh. The advantages, disadvantages, and difficulties encountered in application of the FEM for this problem are outlined and discussed. Several programs, based on multiconductor transmission line theory, are developed for application to Electromagnetic Interference and Compatibility (EMI/C) problems for crosstalk and radiated emission analysis. To verify the model experimentally, a simple printed circuit board consisting of five parallel conductors in microstrip configuration was constructed and measured in both time domain and frequency domains. Radiation model results are compared for a multiconductor configuration with numerical results obtained using the Numerical Electromagnetics Code (NEC) moment method program.
