Abstract
In this work, a novel CNT-filled solderable anisotropic conductive adhesive (SACA) containing a low melting-point alloy (LMPA) and multi-walled carbon nanotubes (MWNTs) was proposed. To evaluate the influence of MWNT concentration on the interconnection properties of SACA joints, six types of CNT-filled SACAs with different chemically functionalized MWNT content (from 0 to 2 wt%) were formulated. At a low MWNT concentration, a stable conduction path was formed due to the excellent coalescence and wetting behavior of the molten LMPA filler, and the electrical and mechanical properties of the CNT-filled SACA joints were also enhanced due to the reinforcing effect of MWNTs. However, the conduction path area decreased with increasing MWNT content due to increased polymer viscosity and diminished molten LMPA mobility, which attenuated the bonding properties.
