Usage
This primary brightener for acidic copper plating baths utilizes a disulfide structure to precisely refine copper crystallization. It significantly enhances surface leveling and deposit brightness while eliminating depressions caused by height differentials. When formulated with polyethers, dyes, and DPS, it ensures uniform copper plating in high-aspect-ratio through-holes and blind vias, making it a standard additive for high-end circuit board plating.
