Handbook Of Fine Pitch Surface Mount Technology

Surface mount technology (SMT) is a mature technology. SMT allows placement of more surface mount components (SMC) into smaller and tighter printed circuit board (PCB) areas. This increased density means increased performance and power in smaller packaging systems, and allows manufacturing of smaller and higher performance products at lower cost. The advance of integrated circuit (IC) technology and the requirements of high density for high-speed circuity is driving the design of SM C to higher pin count and smaller package size. In general, the higher pin count and smaller package size are accomplished by reducing the bond pad size and spacing (pitch) on the chip level and the lead/pin/solder dimensions and pitch on the chip carrier (module) level. The last few years have witnessed an explosive growth in the research and development efforts devoted to FPT as a direct result of the rapid growth of SMT and miniaturization. Some examples are: hand held lightweight video recorders that can take sharp pictures, hand held lightweight devices that can track the worldwide package movements, and portable computers with tiny yet powerful microprocessors and large memory capability that can fit into a briefcase or into the palm of your hand.

Fine pitch high lead count integrated circuit packages represent a dramatic change from the conventional methods of assembling electronic components to a printed interconnect circuit board. To some, these FPTpackages appear to bean extension of the assembly technology called surface mount or SMT. Many of us who have spent a significant amount of time developing the process and design techniques for these fine pitchpackages haveconcluded that these techniquesgobeyondthose commonly useed for SMT. In 1987 the presentauthor, convincedofthe uniqueness ofthe assembly and design demands ofthese packages, chaired ajoint committee where the members agreed to use fine pitch technology (FPT) as the defining term for these demands. The committee was unique in several ways, one being that it was the first time three U. S. standards organizations, the IPC (Lincolnwood, IL), theEIA(Washington, D. C. ),and theASTM (Philadelphia),cametogether tocreate standards before a technology was in high demand. The term fine pitch technology and its acronym FPT have since become widely accepted in the electronics industry. The knowledge of the terms and demands of FPT currently exceed the usage of FPT packaged components, but this is changing rapidly because of the size, performance, and cost savings of FPT. I have resisted several past invitations to write other technical texts. However, I feel there are important advantages and significant difficulties to be encountered with FPT.

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.

This is a state-of-the-art guide to SMT with fine pitch components intended for professionals in electronics manufacturing. The overriding objective is to equip manufacturing people in the electronics industry with a better understanding of the manufacturing processes involved.

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.

This thoroughly revised and updated three volume set continues to be the standard reference in the field, providing the latest in microelectronics design methods, modeling tools, simulation techniques, and manufacturing procedures. Unlike reference books that focus only on a few aspects of microelectronics packaging, these outstanding volumes discuss state-of-the-art packages that meet the power, cooling, protection, and interconnection requirements of increasingly dense and fast microcircuitry. Providing an excellent balance of theory and practical applications, this dynamic compilation features step-by-step examples and vital technical data, simplifying each phase of package design and production. In addition, the volumes contain over 2000 references, 900 figures, and 250 tables. Part I: Technology Drivers covers the driving force of microelectronics packaging - electrical, thermal, and reliability. It introduces the technology developer to aspects of manufacturing that must be considered during product development. Part II: Semiconductor Packaging discusses the interconnection of the IC chip to the first level of packaging and all first level packages. Electrical test, sealing, and encapsulation technologies are also covered in detail. Part III: Subsystem Packaging explores board level packaging as well as connectors, cables, and optical packaging.

Ceramics were among the first materials used as substrates for mass-produced electronics, and they remain an important class of packaging and interconnect material today. Most available information about ceramic electronics is either outdated or focused on their materials science characteristics. The Ceramic Interconnect Technology Handbook goes beyond the traditional approach by first surveying the unique properties of ceramics and then discussing design, processing, fabrication, and integration, as well as packaging and interconnect technologies. Collecting contributions from an outstanding panel of experts, this book offers an up-to-date overview of modern ceramic electronics, from design and material selection to manufacturing and implementation. Beginning with an overview of the development, properties, advantages, and applications of ceramics, coverage spans electrical design, testing, simulation, thermomechanical design, screen printing, multilayer ceramics, photo-defined and photo-imaged films, copper interconnects for ceramic substrates, and integrated passive devices in ceramic substrates. It also offers a detailed review of the surface, thermal, mechanical, and electrical properties of various ceramics as well as the processing of high- and low-temperature cofired ceramic (HTCC and LTCC) substrates. Opening new vistas and avenues of advancement, the Ceramic Interconnect Technology Handbook is the only source for comprehensive discussion and analysis of nearly every facet of ceramic interconnect technology and applications.
