Available in PDF, EPUB and Kindle. Book excerpt: Solder defects in surface-mount technology (SMT) assembly have been an issue for decades. Further, the combined challenges of Pb-free soldering and ever-increasing miniaturization have resulted in new or exacerbated defects in electronics assembly, but there are proven ways to avoid defects. Indium Corporations' Christopher Nash and Dr. Ronald C. Lasky address six top defect topics, as well as how to avoid them, including (1) voiding in bottom-termination components, (2) graping, (3) head-in-pillow and non-wet opens, (4) tombstoning of passive components, (5) insufficients, and (6) solder balling and beading. This book will be especially beneficial to PCB assemblers in improving their assembly processes and the reliability of the end-product, eliminating field failures, and reducing costs.

Download or read book The Printed Circuit Assembler s Guide To SMT Inspection Today Tomorrow and Beyond written by Koh Young America and published by . This book was released on 2021-04-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brent Fischthal: Currently, surface mount technology lines are monitored by two key inspection processes. The first, SPI, reviews the printed circuit board after solder paste has been applied and before components are placed. The second, AOI, reviews the PCB assembly after the board has been assembled and reflowed (or soldered). Now technologists are also using AOI pre-reflow to ensure parts are placed correctly before they are soldered into place.Beyond their job of identifying errors and preventing incorrect boards from continuing along the line, these inspection processes provide the data needed to improve the performance of the entire line. SPI and AOI can both be used to make live line adjustments to improve quality without stopping the line, and to provide data that helps identify the root causes of failures or variances.For companies to succeed in the development of Industry 4.0-and perhaps even beyond as we drive toward manufacturing autonomy-they will need inspection solutions, and inspection partners, that can combine domain expertise in optical inspection (vision and software) with the ability to connect to larger systems and contribute to process improvement utilizing tools like artificial intelligence.

Download or read book Printed circuit board assembly written by P.J.W. Noble and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Assembly of 'difficult' components onto printed circuit boards is emerging as an important application area for small, fast industrial robots. For other robot tasks - for example paint spraying or arc welding - the applications engineer can rely on a body of published information representing decades of accumulated knowledge about the actual process being automated. But for the process of assembly relatively little systematically presented knowledge exists, mainly because so much manual assembly depends on extremely subtle co-ordination of hand, eye and brain which is hard to represent directly in engineering terms. As for the particular processes of electronic assembly, they have hardly been covered at all in the literature. Yet the design of a good PCB automation system depends crucially on the responsible engineer fully understanding every aspect of the process he or she is automating, whether working for the electronics manufacturer, an automation company, a research laboratory or a machine builder. The author of this book has had extensive practical experience in all these roles: as a source of great detail on most aspects of the electronic assembly process it will be of unique value not only to the robot specialist but well beyond that to anyone needing to understand how printed circuit boards are manufactured. P. G. Davey Acknowledgements The author is indebted to many companies and individuals from within the pcb assembly industry.

Download or read book Solder Joint Reliability written by John H. Lau and published by Springer Science & Business Media. This book was released on 2013-11-27 with total page 649 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Soldering Handbook for Printed Circuits and Surface Mounting written by Howard H. Manko and published by Springer. This book was released on 1986-11-30 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: The printed circuit industry has achieved maturity and universal accep tance. No known interconnection technology threatens to render it obso lete in the foreseeable future. It offers two unique advantages that are important for any assembly technology: quality (reliability) and economy. The mode of component attachment to printed circuit boards, however, is undergoing a radical change. Technical and economic pressures are forcing the industry to convert some or all of its assembly to surface mounting techniques. We are moving away from the traditional large through-the-hole connection with its mechanical security. It is being re placed by a small surface butt and/or lap joint, sometimes with no added mechanical support to the solder. This change requires a complete reas sessment of design, production, and inspection techniques. A major por tion of this book is devoted to the changes imposed by surface mounting. This recent development is an extension of the established hybrid (thick and thin-film) industry. Yet when it is applied to conventional printed circuits, there are major differences. One must view the printed circuit board as a planar surface designed to provide interconnections between electronic devices. The electronic in dustry is using them for mass-production techniques to join discrete, integrated, and special components (leaded and leadless). This book ap plies to all board variations including single-sided, double-sided, multi layer, and flexible circuits.
