The electrically conductive adhesives (ECA) are on the verge of a breakthrough as reliable interconnection materials for electronic components. As the ban of lead (Pb) in the electronics industry becomes a reality, the ECA's could be attractive overall alternatives to high melting point (HMP) Pb-based solder pastes. Environmental life cycle assessment (LCA)(More)
Conductive adhesives are getting growing attention in the electronics industry as they constitute an alternative to lead-free solders and conventional solders. The purpose of the present research is to compare the 10Sn90Pb solder paste to an epoxy based isotropically conductive adhesive (ICA) containing pure silver. The study is done from a life cycle(More)
The social impacts of products and service life cycles are increasingly of interest among policy makers and stakeholders. Workers’ issues are considered to be a source of key inventory data to assess social impacts, and are crucial in moving towards social sustainability. There is a need to develop a social inventory database for evaluating social impacts(More)
We quantify the potential impacts of global food production on freshwater availability (water scarcity footprint; WSF) by applying the water unavailability factor (fwua) as a characterization factor and a global water resource model based on life cycle impact assessment (LCIA). Each water source, including rainfall, surface water, and groundwater, has a(More)
To prevent global warming by supply chain, End-of-Life (EOL) assembly products should be disassembled environmentally and economically for material circulation (Wang and Gupta, 2011). This paper proposes a disassembly system design with an optimal environmental and economic parts selection which harmonizes collected CO2 volumes and recycling cost using a(More)
The social life cycle assessment (S-LCA) is a technique for assessing social impact and potential impact that aims to evaluate the social and socio-economic aspects of products and their potential for both positive and negative impacts along their life cycle. The lack of a quantitative inventory data for social issues is a weakness of the S-LCA methodology(More)
Interest in the impacts of water use in the life cycle of products and services are increasing among various stakeholders. The water footprint is a tool to identify critical and effective points for reducing the impact of water use through the entire life cycle of products, services, and organizations. The purpose of this study was to develop a water(More)
