Abstract: The present invention discloses a substrate within a Ni/Au structure electroplated on electrical contact pads and a method for fabricating the same. The method comprises: providing a substrate with a circuit layout pattern and forming a conducting film on the surface of the substrate; depositing a first photoresist layer within an opening on said electrical conducting film surface to expose a portion of said circuit layout pattern to be electrical contact pads; removing the exposed conducting film uncovered by the first photoresist layer; depositing a second photoresist layer, covering the conducting film exposed in the openings of the first photoresist layer; electroplating Ni/Au covering the surface of the electrical contact pads; removing the first and second photoresists, and the conducting film covered by the photoresists; depositing solder mask on the substrate within an opening to expose said electrical contact pads.
