On the Properties of Conductive Adhesive Filled with Electroless Silver Plated Flake Graphite

Abstract

The properties of the conductive adhesive such as resistivity, shear strength and water -absorb ratio of the adhesive filled with the filler of Ag-coated graphite from electroless silver plating procedure were studied using the universal meter, the diagrams of scanning electron microscopy (SEM) and the shear strength testing. The results from the experiment showed that the resistivity of the Ag-coated flake graphite was relative lower when the addition was less than 50 % (wt) to that of the conductive adhesives filled with pure flake graphite. The shear strength of the conductivity adhesive filled with Ag-coated flake graphite was usually higher than that one filled with un-treated graphite and the peak values occurred when the filler addition was equal to 30%.
