1. The anti-corrosion function of connector coatings. The primary consideration in the production of connectors is corrosion resistance. The contact springs of electronic connectors are mostly made of copper alloys, which are prone to corrosion in typical working environments, such as oxidation and sulfuration. In fact, contact coatings are used to isolate the contact springs from the working environment to prevent copper corrosion. Optimizing the interface is an important factor in selecting suitable contact coating materials as a key function of corrosion protection. 2. Connector coatings help improve mechanical performance. The parameters related to mechanical performance mainly affect the durability or wear of the coating and the bonding strength. These factors represent two different perspectives under the same basic effect, namely the sharing of multi-point contact interfaces during relative motion, which can lead to cold welding. Important mechanical properties include the hardness, ductility, and friction coefficient of the coating material. All these properties depend on the inherent characteristics of the coating material and its processing methods. 3. Connector coatings help improve electrical performance. One of the main requirements for the electrical performance of connectors is to establish and maintain stable connector impedance. To achieve this, a metallic contact interface is needed to provide this inherent stability. The establishment of this contact interface requires that the surface film can avoid cracking during the contact and fitting process. 4. Connectors are characterized by being coated with precious metals. The essence of precious metal coatings (such as gold, palladium, and their alloys) is that they are to varying degrees free from the surface film. For these coatings, establishing metal contact at the interface is relatively simple, as it only requires the mating surface to move during fitting. To maintain the stability of the contact interface impedance, connector design requires that the precious metal on the contact surface remains unchanged to prevent the influence of external factors such as contaminants, substrate metal diffusion, and contact wear.

4. Connectors are characterized by being plated with precious metals. The essence of precious metal coatings (such as gold, palladium, and their alloys) is to be somewhat detached from the surface film. For these coatings, making metal contact at the interface is relatively simple, as it only requires the mating surface to move during fitting. To maintain the stability of the contact interface impedance, connector design requires that the precious metal on the contact surface remains unchanged to prevent the influence of external factors such as contaminants, substrate metal diffusion, and contact wear.
