WebFeb 1, 2024 · Decrease operating pH in the SN plating bath. For normal rack plating applications, the operating pH target is 4.0. For barrel plating, it is important to reduce the pH with a high-quality sulfamic acid or proprietary pH adjustment component to 3.0. This lower operating pH maintains the deposit and solution activity to minimize any potential ...
