The service life of the radio frequency pogo pin has an impact

　　The service life of the radio frequency pogo pin has an impact

　　1. Pogo pin spring thimble working stroke selection

　　When choosing a pogo pin spring thimble, it must be based on the space of the product used. Choose the one within the working stroke range; too little space will over-compress the spring of the pogo pin spring thimble, which will affect the service life. If the space is too large, it may be The contact is not in place, the impedance is unstable, and the phenomenon of instantaneous interruption occurs.

　　2. Selection of plating materials

　　Electroplating materials can increase conductivity, prevent oxidation, and resist wear in radio frequency pogo pins. Different materials have different functions. For example, gold has good conductivity. For high-current connectors, it has high impedance requirements. Products generally choose electroplated gold.

　　3. What are the effects of electroplating film thickness

　　pogo pin spring thimble will produce a certain amount of friction when it is in contact when it is working, it will wear out after a long time, and the thickness of the electroplating film will have a great impact on the service life of the product. When used to a certain limit, the plating layer is worn away, and there may be phenomena such as excessive resistance and unstable impedance. The electroplating layer of the 100,000-time spring antenna thimble must be thicker than that of the 10,000-time spring antenna, so please be sure to select the plating requirements according to your needs when selecting the product;

　　Fourth, the influence of elasticity

　　The contact force of the pogo pin spring thimble comes from the internal spring. The size of the spring force can directly affect the impedance and stability of the spring antenna thimble; if the spring force is too large, the friction coefficient will increase, which will affect the service life of the spring antenna thimble. Influence.
