1. Surface roughness of the substrate before plating: the smaller the surface roughness value of the substrate, the smaller the surface roughness value after plating;
2. The temperature of the plating solution: the higher the temperature, the larger the surface roughness value after plating;
3. The size of the current density: the greater the current density, the greater the surface roughness value after plating;
4. The concentration of the plating solution: the larger the concentration of the plating solution, the larger the surface roughness value after plating;
5. Electroplating time: The longer the electroplating time, the greater the surface roughness value after plating.
