Cost and Manufacturing Differences Between Hard Gold and Immersion Gold

Gold plating is a costly process, and selecting the right type is essential for maintaining both performance and budget efficiency. Hard gold plating and immersion gold plating differ in manufacturing complexity and overall cost.

Manufacturing Process Comparison

• Hard Gold Plating: Uses electroplating to deposit gold with added nickel or cobalt, forming a durable coating. This process is precise but requires significant material use.
• Immersion Gold Plating: Uses a chemical reaction to deposit a thin layer of gold onto a nickel base. This method consumes less gold and creates a smooth, uniform finish.

Cost Considerations

Which Plating Method is More Cost-Effective?

Hard gold plating is more expensive due to its thickness and durability, making it ideal for high-wear applications. Immersion gold, on the other hand, is more affordable and is preferred for applications requiring a flat, solderable surface, such as printed circuit boards (PCBs).
