Effects of nanofiber materials of nanofiber anisotropic conductive adhesives (nanofiber ACAs) for ultra-fine pitch electronic assemblies

We investigate the effects of material properties of nanofiber on fine pitch ACA interconnection stability in terms of thermal and mechanical properties. Three kinds of nanofiber materials, polyvinylidene fluoride (PVDF), ethylene vinyl alcohol (EVOH), and Nylon 6, which have different tensile properties and melting temperatures, are coupled with conductive particles to form PVDF-CPIN, EVOH-CPIN, and Nylon 6-CPIN, respectively, and the three nanofiber ACAs are fabricated and characterized.
