Surface-mount Technology for PC Boards


Book Description

Learn to generate high manufacturing yields, low testing costs, and reproducible designs using the latest components of surface mount technology (SMT)! Manufacturers, managers, engineers, students, and others who work with printed-circuit boards will find a wealth of cutting-edge information about SMT and fine pitch technology (FPT) in this new edition. Practical data and clear illustrations combine to clearly and accurately present the details of design-for-manufacturability, environmental compliance, design-for-test, and quality/reliability for today's miniaturized electronics packaging.




Surface Mount Technology


Book Description

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.







Solder Paste in Electronics Packaging


Book Description

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.

Soldering in Electronics Assembly


Book Description

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
