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
| Electrolytic degreasing solution | Electrolytic degreasing powder | 50~70g/L |
| Temperature | 55~65℃ | |
| Pickling solution | HCl | 130~160g/L |
| Temperature | room temperature | |
| Tin plating solution | Sn2+ | 70~180g/L |
| CH4O3S | 55~65g/L | |
| Wake up agent | 30~50mL/L | |
| Temperature | 40~50℃ |
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)=V0.1N 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)=V1N sodium hydroxide (ml) * 19.2
