Advanced packaging applications are demanding increasingly more innovative materials sets in order to ensure overall package reliability. In addition, as we migrate towards higher-density inter-connects, the assembly operation will require new processes and process materials to guarantee both performance and manufacturability. This book explores the questions of materials, processes and reliability for high-density package solutions. The book is strengthened by invited and contributed papers from a host of national and international experts. Topics include: interfacial adhesion behavior; flip-chip interconnections; high-density substrates; thermomechanical behavior and packaging reliability issues.
