Tin Plating Plant Tin Plating Equipment

1.Technological process of production

pay off→electrolytic degreasing→water rinsing→pickling→water rinsing→tin plating→water rinsing→neutralization→water rinsing→drying→take up

2.Main process introduction

Electrolytic degreasing: remove the oil on the surface of copper wire to ensure the binding force of the coating .

Pickling: remove the oxide from the surface of the copper wire.

Water rinsing: clean the wire thoroughly after the tank to avoid mutual contamination of the tank.

Tin plating: the copper wire is coated with a uniform coating.

Neutralization:neutralize the acid on the surface of copper wire to prevent discoloration on the surface of the product.

3.Solution preparation

4.Solution analysis

(1) Analysis of divalent tin content
1.1 Pipette 2ml of plating solution into a 250ml conical flask;
1.2 Add 100ml of deionized water and 20ml of 1:1 HCl;
1.3 Add 8 drops of starch indicator;
Titrate with 0.1N iodine standard solution to blue as the endpoint;
1.5 Calculate the concentration of divalent tin ions:

Sn²⁺(g/l)=V_{0.1N iodine solution} (ml)* 2.97
(2) Analysis of Methanesulfonic acid content
2.1 Pipet 5ml of plating solution into a 250ml conical flask;
2.2 Add pure water to 100ml;
2.3 Add 8 drops of PAN indicator;
2.4 Titrate with 1N sodium hydroxide standard solution until it turns red, and record the milliliters of titration;
2.5 Calculation of free acid content:

ACID (g/l)=V_{1N sodium hydroxide} (ml) * 19.2
