Managers, engineers and technicians will use this book during industrial construction of electronics assemblies, whilst students can use the book to get a grasp of the variety of methods available, together with a discussion of technical concerns. It includes over 200 illustrations, including a photographic guide to defects, and contains many line drawings, tables and flow charts to illustrate the subject of electronics assembly. Soldering in Electronics Assembly looks theoretically at everything needed in a detailed study, but in a practical manner. It examines the soldering processes in the light of electronic assembly type; solder; flux; and cleaning requirements. It has information on every available process, from the most basic hand soldering through to latest innovatory ones such as inert atmosphere wave soldering and zoned forced convection infra-red machines. The book provides a detailed analysis of solder and soldering action; purpose of flux and relevant flux types for any application; classification of assembly variants; assessment and maintenance of solderability. There is also a detailed analysis of soldering process defects and causes. In addition, Soldering in Electronics Assembly contains a new chapter on Ball Grid Array (BGA) technology. - A practical guide for the industry covering all the main soldering processes currently in use - Cleaning, faults, troubleshooting and standards are all major topics - Considers safety and solder process quality assessment

One of the strongest trends in the design and manufacture of modern electronics packages and assemblies is the utilization of surface mount technology as a replacement for through-hole tech nology. The mounting of electronic devices and components onto the surface of a printed wiring board or other substrate offers many advantages over inserting the leads of devices or components into holes. From the engineering viewpoint, much higher lead counts with shorter wire and interconnection lengths can be accommo dated. This is critical in high performance modern electronics packaging. From the manufacturing viewpoint, the application of automated assembly and robotics is much more adaptable to high lead count surface mounted devices and components. Indeed, the insertion of high lead count parts into fine holes on a substrate might often be nearly impossible. Yet, in spite of these surface mounting advantages, the utilization of surface mount technology is often a problem, primarily due to soldering problems. The most practical soldering methods use solder pastes, whose intricacies are frequently not understood by most of those involved in the engineering and manufacture of electronics assemblies. This publication is the first book devoted exclusively to explanations of the broad combination of the chemical, metallurgical, and rheological principles that are critical to the successful use of solder pastes. The critical relation ships between these characteristics are clearly explained and pre sented. In this excellent presentation, Dr. Hwang highlights three impor tant areas of solder paste technology.

Originally conceived as a supplement to the SMTA Certification Program, this book is a must-have reference manual for all process engineers working in the electronics industry as well as anyone just entering the industry. The book provides an in-depth understanding of the entire electronic assembly process. Chapter topics include soldering and materials, printed wiring boards, components, paste-print stencil, component placement, assembly line design and optimization, solder reflow, wave soldering, dispensing, and inspection and test.

Getting Started with Soldering not only teaches new makers and experimenters the core principles of soldering, it also functions as an excellent reference and resource for beginners and more advanced makers alike. The book guides readers through the fundamentals of soldering, explains the tools and materials, demonstrates proper techniques, and shows how to fix mistakes or broken connections. It even includes guidance on more advanced techniques such as surface-mount soldering for electronics. From choosing the right soldering iron to making perfect connections, readers will acquire the knowledge and skills needed to form a strong foundation for a lifetime of making. Soldering is a core concept in making, electronics prototyping, and home repairs The many different types of soldering -- requiring different materials and tools -- are explained with easy-to-follow instructions Full-color photographs and illustrations throughout create a visually engaging format for learning Pricing and technical considerations help readers select the best tools for their budgets and needs Troubleshooting guidelines show how to repair solder connections that have failed from improper technique or from age

Covers various soldering methods and techniques as well as the latest on solder alloys, solder films, surface preparation, fluxes and cleaning methods, heating methods, inspection techniques, and quality control and reliability. Geared to scientists, material engineers, designers, manufacturing engineers, and technologists who need immediate practical guidance rather than theoretical instruction.
