Abstract

Electrically Conductive Adhesives(ECAs) with solderable particles have been developed as an alternative to Pb-free solders. Our previous study proved that good wettability of solder particle is a prerequisite for the establishment of conduction paths. In this paper, two types of ECAs were formulated and the wetting characteristic low-melting-point Sn-In solder on Cu and Ni/Au pads was investigated. It was found that Sn-In solder in the developed resin material with reduction capability shows good wettability, especially on Cu pad.
