Overview
This critical volume provides an in-depth presentation of copper wire bonding technologies, processes and equipment, along with the economic benefits and risks. \xa0Due to the increasing cost of materials used to make electronic components, the electronics industry has been rapidly moving from high cost gold to significantly lower cost copper as a wire bonding material. \xa0However, copper wire bonding has several process and reliability concerns due to its material properties. \xa0Copper Wire Bonding book lays out the challenges involved in replacing gold with copper as a wire bond material, and includes the bonding process changes-bond force, electric flame off, current and ultrasonic energy optimization, and bonding tools and equipment changes for first and second bond formation. \xa0In addition, the bond-pad metallurgies and the use of bare and palladium-coated copper wires on aluminum are presented, and gold, nickel and palladium surface finishes are discussed. \xa0The book also discusses best practices and recommendations on the bond process, bond-pad metallurgies, and appropriate reliability tests for copper wire-bonded electronic components.In summary, this book:Introduces copper wire bonding technologiesPresents copper wire bonding processesDiscusses copper wire bonding metallurgiesCovers recent advancements in copper wire bonding including the bonding process, equipment changes, bond-pad materials and surface finishesCovers the reliability tests and concernsCovers the current implementation of copper wire bonding in the electronics industry\xa0Features 120 figures and tablesCopper Wire Bonding is an essential reference for industry professionals seeking detailed information on all facets of copper wire bonding technology.
