Pogo pin probes are widely used because of their own characteristics. There are many factors that affect the performance of the pogo pin. Let's take a look at it with Wanchang's editor.
1. Selection of electroplating materials:
The electroplating material has the effects of increasing conductivity in the pogo pin, preventing oxidation, anti-wear and other effects. Different materials have different effects. Just like gold, it has good conductivity. It is aimed at high current connectors and impedance requirements. Higher products usually choose electroplated gold.
2. Pogo pin electroplating film:
A certain amount of friction will occur due to certain contact during work, and wear will occur over time. The thickness of the electroplating film will have a particularly large impact on the service life of the product. The electroplating layer will be worn away when it is used to a certain extent. It may happen that the resistance is too large and the impedance is unstable.
3. Selection of work schedule:
When choosing a pogo pin, it must be determined according to the space of the product used. If the pogo pin is selected within the range of the working stroke, too little space will make the spring of the pogo pin excessively compressed, affecting the service life, and too much space may cause contact failure When in place, the impedance is unstable, instantaneous and so on.
4. The influence of pogo pin elasticity:
The contact force of the pogo pin comes from the internal spring. The elastic force of the spring has a direct effect on the impedance of the pogo pin. What is the stability and too much elastic force will increase the friction coefficient and have a certain impact on the service life of the pogo pin.
