Abstract:One of the main cost factors in the wire bonding process are consumables such as bonding tools. The technological transition to copper as wire material causes significant wear on the millimeter size effective contact area of the bonding tool. This wear leads to a reduction of the number of reliable interconnections which can be produced using a single tool by a factor of 30 replacing the wire material from aluminum to copper. To reduce setup time in the production and minimize costs, an increase in bonding too… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
