Abstract: A microelectronic assembly and method for fabricating the same are described. In an example, a microelectronic assembly includes a microelectronic device having a surface with one or more areas to receive one or more solder balls, the one or more areas having a surface finish comprising Ni. A solder material comprising Cu, such as flux or paste, is applied to the Ni surface finish and one or more solder balls are coupled to the microelectronic device by a reflow process that forms a solder joint between the one or more solder balls, the solder material comprising Cu, and the one or more areas having a surface finish comprising Ni.
