EMC at Component and PCB Level By Martin O 'Hara 

Synopsis: 
This book provides the knowledge and good design practice for the design or test engineer to take the necessary measures to improve EMC performance and therefore the chance of achieving compliance, early on in the design process. There are many advantages for both the component supplier and consumer, of looking at EMC at component and PCB level. For the suppliers, not only will their products have the competitive edge because they have known EMC performance, but they will be prepared should EMC compliance become mandatory in the future. For consumers, it is a distinct advantage to know how a component will behave within a system with regard to EMC. This book shows how to achieve EMC compliance early on in the design process; provides the knowledge to trace system EMC performance problems; and, follows best design practices. 

Printed Circuit Board Design Techniques for EMC Compliance: A Handbook for Designers (IEEE Press Series on Electronics Technology) By Mark I Montrose 

Synopsis: 
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 maths. 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.

Optimal Production Planning for PCB Assembly (Springer Series in Advanced Manufacturing)
By William Ho, Ping Ji 

Synopsis:
Printed circuit boards (PCBs) play a vital role in our daily lives. With increasing applications of PCBs, one way to increase a PCB manufacturer's competitiveness in terms of operation efficiency is to minimize production time. This is the first book to focus on the optimisation of the PCB assembly lines' efficiency. It integrates the component sequencing and the feeder arrangement problems together for the pick-and-place machine and the chip shooter machines; constructs mathematical models and develops an effective heuristic solution approach for the integrated problems of placement machines, the line assignment problem, and the component allocation problem; and develops a prototype of the PCB assembly planning system. The techniques proposed will enable process planners in the electronics industry to improve their assembly line's efficiency. Graduate students in operations research can use this to familiarise themselves with the techniques and applications of mathematical modelling.
