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.

The book focuses on the design, materials, process, fabrication, failure mechanism, reliability, modeling, and thermal management of chiplets and heterogeneous integration. Both principles and engineering practice have been addressed, with more weight placed on engineering practice. This is achieved by providing in-depth study on a number of major topics such as hybrid bonding, advanced substrates, failure mechanisms, and modeling due to thermal stresses, moisture absorption, impact loading such as drop as well as electric current driven electromigration, and the fundamentals of thermal management. Each topic is treated with in-depth analysis to bridge foundational principles with real-world engineering challenges. This book is an essential resource for researchers, engineers, and students in electrical engineering, mechanical engineering, materials science, and industrial engineering, equipping them with the knowledge to advance innovation in semiconductor packaging and integration.
