What is Palladium Plating?
Palladium Plating is an electroplating process that deposits a thin layer of palladium onto a component surface to improve electrical performance, corrosion resistance, wear resistance, and contact reliability.
Palladium belongs to the platinum group metals (PGMs) and offers many of the benefits of gold plating while providing improved hardness and lower material cost in certain applications.
Palladium plating provides:
- Excellent corrosion resistance
- Low contact resistance
- High wear resistance
- Superior oxidation resistance
- Long contact life
- Good solderability
- Cost-effective precious metal protection
Palladium is often used as an alternative to gold plating for connector and contact applications.
Benefits of Palladium Plating
