The rapid growth of the use of optoelectronic technology in Information and Communications Technology (ICT) has seen a complementary increase in the performance of such technologies. As a result, optoelectronic technologies have replaced the technology of electronic interconnections. However, the control of manufacturing techniques for optoelectronic systems is more delicate than that of microelectronic technologies.This practical resource, divided into four chapters, examines several methods for determining the reliability of infrared LED devices. The primary interest of this book focuses on methods of extracting fundamental parameters from the electrical and optical characterization of specific zones in components. Failure mechanisms are identified based on measured performance before and after aging tests. Knowledge of failure mechanisms allows formulation of degradation laws, which in turn allow an accurate lifetime distribution for specific devices to be proposed. - Deals exclusively with reliability, based on the physics of failure for infrared LEDs - Identifies failure mechanisms, lifetime distribution, and selection of the best component for dedicated applications - Uses a complete methodology to reduce the number of samples needed to estimate lifetime distribution - Focuses on the method to extract fundamental parameters from electrical and optical characterizations

Reliability and Failure Analysis of High-Power LED Packaging provides fundamental understanding of the reliability and failure analysis of materials for high-power LED packaging, with the ultimate goal of enabling new packaging materials. This book describes the limitations of the present reliability standards in determining the lifetime of high-power LEDs due to the lack of deep understanding of the packaging materials and their interaction with each other. Many new failure mechanisms are investigated and presented with consideration of the different stresses imposed by varying environmental conditions. The detailed failure mechanisms are unique to this book and will provide insights for readers regarding the possible failure mechanisms in high-power LEDs. The authors also show the importance of simulation in understanding the hidden failure mechanisms in LEDs. Along with simulation, the use of various destructive and non-destructive tools such as C-SAM, SEM, FTIR, Optical Microscopy, etc. in investigation of the causes of LED failures are reviewed. The advancement of LEDs in the last two decades has opened vast new applications for LEDs which also has led to harsher stress conditions for high-power LEDs. Thus, existing standards and reliability tests need to be revised to meet the new demands for high-power LEDs. - Introduces the failure mechanisms of high-power LEDs under varying environmental conditions and methods of how to test, simulate, and predict them - Describes the chemistry underlying the material degradation and its impact on LEDs - Discusses future directions of new packaging materials for improved performance and reliability of high-power LEDs

Since the first light-emitting diode (LED) was invented by Holonyak and Bevacqua in 1962, LEDs have made remarkable progress in the past few decades with the rapid development of epitaxy growth, chip design and manufacture, packaging structure, processes, and packaging materials. LEDs have superior characteristics such as high efficiency, small size, long life, low power consumption, and high reliability. The market for white LED is growing rapidly in various applications. It has been widely accepted that white LEDs will be the fourth illumination source to substitute the incandescent, fluorescent, and high-pressure sodium lamps. With the development of LED chip and packaging technologies, the efficiency of high power white LED will broaden the application markets of LEDs while changing the lighting concepts of our lives. In LED Packaging for Lighting Applications, Professors Liu and Luo cover the full spectrum of design, manufacturing, and testing. Many concepts are proposed for the first time, and readers will benefit from the concurrent engineering and co-design approaches to advanced engineering design of LED products. One of the only books to cover LEDs from package design to manufacturing to testing Focuses on the design of LED packaging and its applications such as road lights Includes design methods and experiences necessary for LED engineers, especially optical and thermal design Introduces novel LED packaging structures and manufacturing processes, such as ASLP Covers reliability considerations, the most challenging problem for the LED industry Provides measurement and testing standards, which are critical for LED development, for both LED and LED fixtures Codes and demonstrations available from the book’s Companion Website This book is ideal for practicing engineers working in design or packaging at LED companies and graduate students preparing for work in industry. This book also provides a helpful introduction for advanced undergraduates, graduates, researchers, lighting designers, and product managers interested in the fundamentals of LED design and production.

In the past four years we have witnessed rapid development in technology and significant market penetration in many applications for LED systems. New processes and new materials have been introduced; new standards and new testing methods have been developed; new driver, control and sensing technologies have been integrated; and new and unknown failure modes have also been presented. In this book, Solid State Lighting Reliability Part 2, we invited the experts from industry and academia to present the latest developments and findings in the LED system reliability arena. Topics in this book cover the early failures and critical steps in LED manufacturing; advances in reliability testing and standards; quality of colour and colour stability; degradation of optical materials and the associated chromaticity maintenance; characterization of thermal interfaces; LED solder joint testing and prediction; common failure modes in LED drivers; root causes for lumen depreciation; corrosion sensitivity of LED packages; reliability management for automotive LEDs, and lightning effects on LEDs. This book is a continuation of Solid State Lighting Reliability: Components to Systems (published in 2013), which covers reliability aspects ranging from the LED to the total luminaire or system of luminaires. Together, these two books are a full set of reference books for Solid State Lighting reliability from the performance of the (sub-) components to the total system, regardless its complexity.

Based on deep theoretical as well as practical experience in Reliability and Quality Sciences, Robust Design Methodology for Reliability constructively addresses practical reliability problems. It offers a comprehensive design theory for reliability, utilizing robust design methodology and six sigma frameworks. In particular, the relation between un-reliability and variation and uncertainty is explored and reliability improvement measures in early product development stages are suggested. Many companies today utilise design for Six Sigma (DfSS) for strategic improvement of the design process, but often without explicitly describing the reliability perspective; this book explains how reliability design can relate to and work with DfSS and illustrates this with real–world problems. The contributors advocate designing for robustness, i.e. insensitivity to variation in the early stages of product design development. Methods for rational treatment of uncertainties in model assumptions are also presented. This book promotes a new approach to reliability thinking that addresses the design process and proneness to failure in the design phase via sensitivity to variation and uncertainty; includes contributions from both academics and industry practitioners with a broad scope of expertise, including quality science, mathematical statistics and reliability engineering; takes the innovative approach of promoting the study of variation and uncertainty as a basis for reliability work; includes case studies and illustrative examples that translate the theory into practice. Robust Design Methodology for Reliability provides a starting point for new thinking in practical reliability improvement work that will appeal to advanced designers and reliability specialists in academia and industry including fatigue engineers, product development and process/ quality professionals, especially those interested in and/ or using the DfSS framework.
