All connector terminals should have a surface treatment, generally referred to as plating. There are two main reasons for plating connector terminals: one is to protect the substrate of the terminal reeds from corrosion; the other is to optimize the performance of the terminal surfaces and to establish and maintain contact interfaces between the terminals, especially film control. In other words, to make metal-to-metal contact easier. First, connector terminals have three types of tinning: pre-tinned, pre-laminated and electroplated. Tin is relatively soft, corrosion-resistant, relatively inexpensive, easy to solder, and has a coating thickness of 2-12 μ m. Brass or bronze can be tinned at 110 degrees Fahrenheit, and steel can be tinned at 190 degrees. Electroplated gold on the connector terminals is a better plating method for existing electrical contacts. Soft, corrosion-resistant, insoluble in pure acid, with good electrical conductivity. The thickness of gold plating is usually 0.4-3.5 μm.
Second, the basic performance of the connector terminals are as follows: the basic performance of the connector terminals can be divided into three main categories: that is, mechanical performance, electrical performance and environmental performance. 1. The mechanical performance of the connector terminals refers to the insertion force (insertion force, pull-out force and retention force) (if the retention force is too small, it will affect the reliability of the connection) and durability (life expectancy). 2. The electrical performance of connector terminals refers to the connector's main electrical performance, including rated voltage, rated current, contact resistance, insulation resistance and resistance (withstand voltage). 3. Electrical performance of connector terminals refers to the main electrical properties of the connector, including rated voltage, rated current, contact resistance, insulation resistance and resistance (withstand voltage).3. The environmental performance of connector terminals refers to the resistance to temperature, humidity, salt spray, vibration and shock resistance, tin resistance and so on.-3、About BBC Electronic Products Network platform related to the introduction and sales of products briefly: BBC Electronic Products Network - a professional agent / production / sales of a variety of {connectors | wiring harness | wire and cable products}; if you have a related [connectors | wiring harness | wire and cable products] purchasing / sourcing needs or would like to buy / to understand which connectors | wiring harness | wire and cable products we can provide solutions, please contact the following Division Division I business personnel!
