Reflow Soldering: Apparatus and Heat Transfer Processes investigates the technology of reflow soldering from the aspect of the soldering ovens and apparatus. The authors begin by introducing the concept of surface mount technology. This is followed by three chapters exploring: Infrared ovens, convection ovens, Vapor Phase Soldering (VPS), and special reflow ovens. Each of these chapters includes a discussion of the physical background, structure and working principle, and characterization of the heating, flow and vapor parameters; and concludes with a review of the application of the techniques and typical solder failures. The book concludes with a discussion of the various numerical simulations of the different ovens. This book will be useful for researchers and process and quality and research and design engineers within the electronics and manufacturing industries. - Provides an overview and comparison of the existing reflow apparatus, heating methods, and working principles - Analyses and compares the different reflow ovens - Discusses useful tools such as characterization and measurement methods and includes numerical case studies to assist in solving soldering problems and improve soldering quality - Introduces Vapor Phase Soldering (VPS) technology

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

Surface Mount Technology has had a profound influence on the electronics industry, and has led to the use of new materials, techniques and manufacturing processes. Since the first edition of this book was written, electronic assemblies have continued to become still smaller and more complex, while soldering still remains the dominant connecting technique. This is a comprehensive guide to current methods of soldering components to their substrates, written by one of the founding fathers of the technology. It also covers component placement, the post-CFC technology of cleaning after soldering, and the principles and methods of quality control and rework. New sections deal with Ball-Grid-Array (BGA) technology, lead-free solders, no-clean fluxes, and the current standard specifications for solders and fluxes. Dr Rudolf Strauss has spent most of his working life with a leading manufacturer of solders and fluxes. He was responsible for a number of innovations including the concept of wave soldering, and for many years has been active as lecturer, consultant, and technical author. His book explains the principles of soldering and surface mount technology in practical terms and plain language, free from jargon. It is addressed to the man, or woman, who has to do the job, but it will also be of help in planning manufacturing strategy and in making purchasing decisions relating to consumables and equipment. - Written by founding father of SMT technology - Standard specifications have been fully updated - New chapter covering Ball Grid Array (BGA) technology

Solders have given the designer of modern consumer, commercial, and military electronic systems a remarkable flexibility to interconnect electronic components. The properties of solder have facilitated broad assembly choices that have fueled creative applications to advance technology. Solder is the electrical and me chanical "glue" of electronic assemblies. This pervasive dependency on solder has stimulated new interest in applica tions as well as a more concerted effort to better understand materials properties. We need not look far to see solder being used to interconnect ever finer geo metries. Assembly of micropassive discrete devices that are hardly visible to the unaided eye, of silicon chips directly to ceramic and plastic substrates, and of very fine peripheral leaded packages constitute a few of solder's uses. There has been a marked increase in university research related to solder. New electronic packaging centers stimulate applications, and materials engineering and science departments have demonstrated a new vigor to improve both the materials and our understanding of them. Industrial research and development continues to stimulate new application, and refreshing new packaging ideas are emerging. New handbooks have been published to help both the neophyte and seasoned packaging engineer.

A foreword is usually prepared by someone who knows the author or who knows enough to provide additional insight on the purpose of the work. When asked to write this foreword, I had no problem with what I wanted to say about the work or the author. I did, however, wonder why people read a foreword. It is probably of value to know the background of the writer of a book; it is probably also of value to know the background of the individual who is commenting on the work. I consider myself a good friend of the author, and when I was asked to write a few words I felt honored to provide my view of Ray Prasad, his expertise, and the contribution that he has made to our industry. This book is about the industry, its technology, and its struggle to learn and compete in a global market bursting with new ideas to satisfy a voracious appetite for new and innovative electronic products. I had the good fortune to be there at the beginning (or almost) and have witnessed the growth and excitement in the opportunities and challenges afforded the electronic industries' engineering and manufacturing talents. In a few years my involve ment will span half a century.
