Electrically Conductive Adhesives

By Rajesh Gomatam, Kash L. Mittal Copyright 2008

    With all the environmental concerns and constraints today and stricter future regulations, there is a patent need to replace materials noxious to the environment by environmentally-friendly alternatives. Electrically conductive adhesives (ECAs) are one such example. ECAs offer an excellent alternative to lead-solder interconnects for microelectronic packaging applications. ECAs are used in electronics for laptop computers, camcorders, watch electronics, hard-drive suspensions and a myriad of electronic equipments. Environmentally-friendly ECAs offer many advantages vis-à-vis solder, such as simple and low-temperature processing conditions, better thermo mechanical performance and finer pitch. This book is based on the two Special Issues of the Journal of Adhesion Science and Technology (JAST vol. 22, no. 8-9 and vol. 22, no. 14) dedicated to this topic. The book contains a total of 21 papers (reflecting overviews and original research) and is divided into three parts as follows: Part 1: Introduction and Recent Developments, Part 2: Mechanical, Durability and Reliability Aspects and Part 3: Characterization and Properties.
