Methods are disclosed for providing a dual layer of nickel on multilayer ceramic (MLC) hermetic seal bands. The dual layer comprises a layer of electroplated nickel and a layer of electroless nickel. This dual layer improves the seal band metallurgy by providing a void-free, non-porous nickel matrix suitable for hermetic cap sealing.
