The Electroless Nickel does not need a any brightener add back, it only requires Hypophosphite and Nickel soln add backs. There are three kinds of add backs A , B and C, the names may vary depending on you supplier. We use Nichem Ax, and Nichem C. When making new bath we add 30 liters of Nichem Ax and 57 liters of B, the Nichem C contains the hypophosphite and stabilizer which is added along with Nickel add back in a ratio of 1:1. The Nickel add backs are made depending on your titration result. Please consult your supplier for an add back table.
