A Guide to Lead free Solders

The book is important because it reflects a trend, especially in microelectronics manufacture toward recyclability. Europe and Asia are moving towards legislation to ban the use of lead in solders and public demand in the US will likely have the same result. Producers of solders and manufacturers who use them will have to invent and employ suitable substitutes and A Guide to Lead-free Solders will show them how to do so.

Investigations on Microstructure and Mechanical Properties of the Cu Pb free Solder Joint Interfaces

This thesis presents a series of mechanical test methods and comprehensively investigates the deformation and damage behavior of Cu/Pb-free solder joints under different loading conditions. The fracture behavior of Pb-free joint interfaces induced by stress, deformation of solder and substrate are shown, the shear fracture strength of the Cu6Sn5 IMC is measured experimentally for the first time, and the dynamic damage process and microstructure evolution behavior of Pb-free solder joints are revealed intuitively. The thesis puts forward the argument that the local cumulative damage is the major cause of failure in solder joints. The research results provide the experimental and theoretical basis for improving the reliability of solder joints.

Bogatin s Practical Guide to Prototype Breadboard and PCB Design

Printed circuit boards (PCB) are at the heart of every electronic product manufactured today. Yet, engineers rarely learn to design PCBs from a class or course. They learn it by doing, by reading app notes, watching YouTube videos and sitting by the side of an experienced engineer. This book is the foundation building book for all engineers starting out to design PCBs. It teaches good habits designing a PCB, first for connectivity, and secondly, introduces the four most important principles to reduce noise. A seven-step process is presented: developing a plan of record, creating a Bill of Materials, completing the schematic, completing the layout, completing the assembly, conducting bring up and troubleshooting and documenting the project. Each step is developed in detail. In particular, the emphasis in this book is on risk management: what can be done at each step of the process to reduce the risk of a hard-error which requires a complete re-spin, or a soft error, which requires some sort of on-the-fly repair. After connectivity is designed, it’s important to develop good habits to minimize the potential noise from ground bounce, power rail stitching noise, stack up design and reducing switching noise in signal paths. These techniques apply to all designs from 2-layer to 8-layer and more, for bandwidths below 200 MHz. The best practices for manual lead-free soldering are presented so that everyone can become a soldering expert. The best measurement practices using common lab instruments such as the DMM, the constant current/constant voltage power supply, and oscilloscopes are presented so that common artifacts are minimized. Features in the design that help you find design or assembly errors quickly and the troubleshooting techniques to find and fix problems are introduced. Applying the habits presented in this book will help every engineer design their next circuit board faster, with less chance of an unexpected problem, with the lowest noise. This textbook will also have embedded videos to visually demonstrate many of the hands-on processes introduced in this book.

Modelling  Simulation and Control of Thermal Energy Systems

Faced with an ever-growing resource scarcity and environmental regulations, the last 30 years have witnessed the rapid development of various renewable power sources, such as wind, tidal, and solar power generation. The variable and uncertain nature of these resources is well-known, while the utilization of power electronic converters presents new challenges for the stability of the power grid. Consequently, various control and operational strategies have been proposed and implemented by the industry and research community, with a growing requirement for flexibility and load regulation placed on conventional thermal power generation. Against this background, the modelling and control of conventional thermal engines, such as those based on diesel and gasoline, are experiencing serious obstacles when facing increasing environmental concerns. Efficient control that can fulfill the requirements of high efficiency, low pollution, and long durability is an emerging requirement. The modelling, simulation, and control of thermal energy systems are key to providing innovative and effective solutions. Through applying detailed dynamic modelling, a thorough understanding of the thermal conversion mechanism(s) can be achieved, based on which advanced control strategies can be designed to improve the performance of the thermal energy system, both in economic and environmental terms. Simulation studies and test beds are also of great significance for these research activities prior to proceeding to field tests. This Special Issue will contribute a practical and comprehensive forum for exchanging novel research ideas or empirical practices that bridge the modelling, simulation, and control of thermal energy systems. Papers that analyze particular aspects of thermal energy systems, involving, for example, conventional power plants, innovative thermal power generation, various thermal engines, thermal energy storage, and fundamental heat transfer management, on the basis of one or more of the following topics, are invited in this Special Issue: • Power plant modelling, simulation, and control; • Thermal engines; • Thermal energy control in building energy systems; • Combined heat and power (CHP) generation; • Thermal energy storage systems; • Improving thermal comfort technologies; • Optimization of complex thermal systems; • Modelling and control of thermal networks; • Thermal management of fuel cell systems; • Thermal control of solar utilization; • Heat pump control; • Heat exchanger control.

Parents often feel overwhelmed and defenseless against a never-ending recall list of toys and baby products. Deciphering unpronounceable chemicals they encounter every day can be daunting if not impossible. With environmental exposures being closely linked to 70 percent of birth defects, new parents faced with the overwhelming responsibility for their babies' health frequently turn to organic products. But they quickly find they don't have the time to practice a completely green or natural lifestyle. The Smart Mama's Green Guide delivers the information busy parents want and the tools to make informed, individual choices without the demand to go all-out green. Packed with practical tips on eliminating or reducing the hidden dangers of toxic chemicals that lurk everywhere, this book will empower readers to control what comes into their homes and make informed decisions instead of relying on government regulation of harmful chemicals.
