Electroless nickel plating process sequence

A. Hi Yogesh. My personal opinion is that it is foolish for someone with no plating experience to try to design a plating line and establish a plating process on their own without a consultant ... or as a minimum hiring an experienced plater, taking a plating course, and reviewing a few books on the subject.

But if you're going to rely on internet advice, step 1 is to determine what health & safety and environmental guidelines you will need to comply with. Then you should have some sample parts plated by an independent shop and tested so you have some idea what sequence will be necessary for satisfactory parts.

As far as the process sequence itself, we need to start with what the parts are, what metal or plastic they are made of, and what environmental conditions they must withstand. Even the most basic question of a generalized pretreatment plating cycle and whether you need rectifiers & anodes will depend on what the substrate is made of -- if any metal other than aluminum, rectifiers and anodes are probably required for the electrocleaning step even if nowhere else. If the parts are copper or brass you also need a plating rectifier to jump start the electroless plating process. Good luck.
