WATTGATE AUDIO GRADE PLATING

Gold Three Layer Plating Process
1. Oxygen free copper plating
improves conductivity
2. Electroless nickel plating
necessary to prevent the leeching of the copper through the pure gold layer
3. 24k gold plating
improves conductivity
Rhodium Four Layer Plating Process
1. Oxygen free copper plating
improves conductivity
2. Electroless nickel plating
necessary to prevent the leeching of the copper through the pure gold layer
3. 24k gold plating
improves conductivity
4. Pure Rhodium plating
Silver Three Layer Plating Process
1. Oxygen free copper plating
improves conductivity
2. Electroless nickel plating
necessary as a diffusion barrier between the copper and pure silver
3. Pure silver plating
improves conductivity
