Alkyl sulfonic acid system adopted, environment friendly, with stable system;

Simple composition, easy operation, easy for site production and management;

Special additive used, contributing to dense and uniform crystals of the coating, with good welding performance, wetting balances T2/3Fmax＜0.5S;

Uniform coating, small thickness difference between coatings in areas with high and low current density.

3461D is a pure tin electroplating potion exclusively designed in accordance with the barrel plating characteristics of such electronic products as passive components. It can ensure uniform and dense tin coating while ensuring the electroplating efficiency, thus ensuring excellent weldability of the plating workpiece. It is applicable to barrel tin plating of chip capacitors, resistors, electric induction products and other electronic.
