Abstract

The characteristics of conductive particles in anisotropically conductive adhesives (ACA) were studied using optical microscope and nano-indenter. The indentation measurements were performed at the particles in ACA joints using different bonding forces. The load-displacement curves and microhardness values are obtained, which indicate that the nano-indenter could be used for quantitative estimates of the electrical and mechanical characteristics of conductive particles in ACA's.
