What are the classifications for RF connector plating?

Author: Date:10/16/2019 7:02:00 PM
   When you purchase the RF connector, you will first tell the manufacturer about the plating requirements. For example, what kind of material is plated, the plating thickness should be explained to the plating manufacturer, or else you will lose it. So understanding the plating classification is very important, The plating classification has the following:

   First, the bright nickel plating layer - it is a widely used and relatively inexpensive plating. It is mainly used for the outer conductor and the housing part of the universal connector. It is used more for general commercial connectors, and its corrosion resistance and salt spray resistance are good. It is not suitable for products with intermodulation requirements.

   Second, bright silver plating - this is the best conductivity plating. For some high-end military products, silver must be plated. However, the hard and hard silver plating is high in cost, and the disadvantage is that after the surface protective film is destroyed, it is easily vulcanized in the atmosphere, yellowing and blackening.


   Third, plated ternary alloy - this is a copper-tin-zinc alloy, the ratio is: copper 55%, tin 30%, zinc 15%. It is a substitute for silver plating and nickel, its chemical properties are relatively stable, and it has been widely used by products with intermodulation requirements.


   Fourth, the gold plating layer - the gold layer is relatively stable, not easy to corrode, and the electrical conductivity is inferior to the silver plating layer. Since the thickness of the gold plating layer directly affects the wear resistance, the thicker the price, the higher the price.
