Applications

1. Electrolyte For Tin And Lead Free Plating In Electronics: Methanesulfonic acid tin plating has become the standard acid system for modern electroplating, so this stannous source is used in tin baths for connectors, terminals, PCB surface finishes and other lead free electronic coatings.

2. Solder Bump Plating For Wafer Level Packaging: Tin silver alloy solder bumps for flip chip interconnections are commonly prepared from methanesulfonic acid based baths, where the electrolyte offers high salt solubility and conductivity and dissolves the metals needed for co electrodeposition.
