Abstract
This study investigated changes in electrical and mechanical properties, as well as the high humidity reliability of 18 μm-diameter silver alloy wires with palladium contents of 1.1, 2.5, 3.0, and 4.0 wt%, for semiconductor packaging. We also compared the formation of Free Air Ball (FAB) and the high humidity reliability..... More

Korean J. Met. Mater. 2023;61(10):793-799.   Published online 2023 Sep 25
DOI: https://doi.org/10.3365/KJMM.2023.61.10.793

Abstract
Polymer composites enriched with conductive fillers hold immense potential for flexible pressure sensors, because of the remarkable piezoresistive effect they possess. Research on polymer composite pressure sensors has been actively ongoing because of their flexibility and high electrical resistance performance. This paper presents a comprehensive comparison of the piezoresistive characteristics..... More
