The decisive factor affecting the performance of pogo pin

　　1. Selection of electroplating materials:

　　Electroplating materials have the functions of increasing conductivity, preventing oxidation, and anti-wear in pogo pins. Different materials have different functions. For example, gold has good conductivity. For high-current connectors, products with high impedance requirements Gold plating is generally chosen.

　　2. Pogo pin plating film:

　　When working, there will be a certain amount of friction due to the contact. After a long time, there will be wear. The thickness of the plating film will have a great impact on the service life of the product. There will be phenomena such as excessive resistance and unstable impedance.

　　3. Selection of working itinerary:

　　When choosing a pogo pin, it must be determined according to the space of the product used. Select the one within the working stroke range. If the space is too small, the spring of the pogo pin will be over-compressed, which will affect the service life. If the space is too large, it may cause inappropriate contact , the impedance is unstable, and the transient phenomenon occurs.

　　4. The influence of pogo pin elasticity:

　　The contact force of the pogo pin comes from the internal spring. The size of the spring elastic force can directly affect the impedance of the pogo pin and how stable it is. If the elastic force is too large, it will increase the friction coefficient and affect the service life of the pogo pin. The above is an introduction to the decisive factors of pogo pin (spring thimble) affecting the performance of pogo pin, I hope it can help you
