Abstract
A new type of electrical conductive adhesives (ECAs) with flaky and spherical silver powder as mixed conductive filler is investigated in this paper. And the mixed filler could achieve the dense packing structure after ultrasonic treatment. According to scanning electron microscope (SEM) images, it can be proved that flaky and spherical silver powder is well dispersed in the epoxy matrix without obvious agglomeration after ultrasonic treatment. The thermal, electrical and mechanical properties of ECAs were characterized. The thermal conductivity of ECAs increases with the raise of silver content. However, the bulk resistivity and tensile–shear strength decreases with the increase of silver content. In addition, small agglomeration and free dispersed spherical silver can improve thermal conductivity of ECAs. The thermal conductivity model is explored in this paper.
