mittent electroless nickel deposition was conducted by periodically removing the substrate from the deposition bath for a few seconds during deposition. The periodic nature of this operation results in a deposition behavior, shown in Fig. 1, analogous to that of pulse electroplating 8 and is thus termed "intermittent electroless nickel deposition."
