2. Some descriptions of mechanical structure, material, surface treatment
The mechanical structure, material, surface treatment on the connector performance and price has great influence. Mechanical structure determines the production efficiency and the use of materials, or materials.
The connectors commonly used are made of brass, bronze, copper, stainless steel, PTFE. Brass and bronze, the price is relatively low, low hardness, easy processing, and high production efficiency. Beryllium copper, stainless steel, high price, high hardness, good elasticity, but the process can.
RF connector for lower resistivity, excellent corrosion resistance oxidation resistance with precious metal plating, such as gold, silver, nickel, etc.. Especially small size effect on the performance of the center conductor requirements more stringent. As a result of these metal prices, the impact on prices is great, general manufacturer’s specifications in the book detailed description of plating thickness.
The user can according to the above factors combined with their own conditions of use, environment and reasonable cost performance good connector.
