Nickel-based alloys are being studied a lot currently in an effort to develop stable barrier films between solder and copper substrate. In this paper, electroplated Ni-21.4%W(Au) coating on the surfaces of copper microcones applying in low temperature solid state bonding has been investigated. X-ray diffraction (XRD) and scanning electron microscopy (SEM) result show that there is no significant change of the surface morphology Cu microcones after plating Ni-W(Au) film. SEM analysis revealed that the Ni-W alloys coating can effectively reduce the interfacial reaction and improve high-temperature anticorrosion prominently in the bonding process. A thin film of Au on the top of Ni-W layer effectively reduces the oxide layer growth. The strength of bonding joint is measured and the result reveals that this method can be used in the industry.
