Metal Surface Condition Effect on Interfacial Property between Metal and Epoxy Resin

Abstract

Conductive adhesives are alternatives to solder joints and are of interest because of their high bonding strength, low thermal resistance, and low electrical resistance. In this paper, we focused on the dependence of the metal surface conditions on the surface processing and clarified the effect of different metal surface finishes on the bonding strength and thermal characteristics. The effects of air exposure and silane coupling agent processing on the adhesive strength between the metal and resin were investigated. The thermal resistance after repeated bending was measured to determine the effect of different metal surface finishes on the thermal resistance.
