3461D Additive for Matte Tin Barrel Plating

Tin plating

Information

Characteristic：

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.

Application：

♕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.

Advantage introduction：

3461D1: Commonly known as make-up. It is used for complexing tin ion to control deposition rate of electroplating and make the plating crystal fine and tight;
3461D2: Supplement. It is used to improve plating current distribution, produce secondary current distribution to make plating uniform, thickness difference between high and low current zone smaller as well as to increase leveling of plating;
Tin Concentrate: to provide the tin ion needed for electroplating deposition.
