2. Technological process of production.
CCS(copper clad steel wire)
pay off→cathode discharge oil→water rinsing→anode discharge oil→water rinsing → pickling→ water rinsing → pre-plating copper → water rinsing → acid copper plating → water rinsing → hot water rinsing → drying→take up
3. Main process introduction.
Degreasing: remove the oil on the surface of product to ensure the binding force of the coating .
Pickling: remove the oxide from the surface of the product.
Water rinsing: clean the product thoroughly after the tank to avoid mutual contamination of the tank.
Chemical zinc plating 1:pre-treatment before electroplating , forming a dense zinc alloy layer.
Dezinc: remove zinc layer and impurities from substrate surface.
Chemical zinc plating 2 : forming a dense zinc alloy layer and improve the binding force of subsequent electroplating.
Pre-copper plating : as a pre-coating, to ensure the subsequent coating and base binding force.
Acid copper plating : thickened copper coating to increase conductivity.
4.Solution preparation
| Pre-plating copper | Cu2+ | 10-17g/L |
| K2CO3 | 20-30g/L | |
| PH | 9.0-10.5 | |
| Temperature | 50~60ºC | |
| Acid copper plating | CuSO4·5H2O | 250-300g/L |
| H2SO4 | 60-100 g/L | |
| Cl- | 100-150mg/L | |
| Leveling agent | 3-15ml/L | |
| Temperature | 40~50ºC | |
5.Solution analysis method
Pre-plating solution: Copper ion concentration
1. Pipette 5 ml of electroplating solution into a 250 ml conical flask,
2. Add approximately 25 ml of deionized water and 2-3g of ammonium persulfate, shake the conical flask to completely dissolve it,
3. Heat to boiling, place, cool to room temperature, add 3-5 ml of concentrated ammonia water, and turn the color into a deep blue.
4. Add 50 ml of deionized water and 4-6 drops of indicator
5. Titrate with 0.1mol/L EDTA until the color turns grayish green.
Calculation: Cu (g/L)=12.71 * C * V
C - Concentration of EDTA standard solution (mol/L)
V - Volume of EDTA standard solution consumed (mL)
Acid copper plating solution: Copper ion concentration
1. Pipette 2 milliliters of plating solution and add 100 milliliters of pure water
2. Heat to 40-50 ºC and add 10 milliliters of 1:1 ammonia water
3. Add 5 drops of PAN indicator
4. Titrate with 0.05mol/L EDTA solution, turning from dark blue to green as the endpoint.
Calculation: CuSO4 · 5H2O (g/L)=C * V * 249.7/n
C - Concentration of standard EDTA solution
V - Volume of solution consumed for titration of EDTA (ml)
249.7- Molecular weight of copper sulfate
n - Number of milliliters taken from the plating solution
6.Product application
