The decisive factor affecting the performance of pogo pin

  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.

The decisive factor affecting the performance of pogo pin(图1)

  1. Selection of electroplating materials:

  The electroplating material has the effect 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 electrical conductivity. It is aimed at high current connectors and impedance requirements. Higher products usually choose electroplated gold.

  2. Pogo pin electroplating film:

  During work, a certain amount of friction will occur due to certain contact, 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 used to a certain extent. The resistance may be too large and the impedance may be unstable.

  3. Selection of work schedule:

  When choosing a pogo pin, it must be determined according to the space of the product used. If you choose a pogo pin within the range of the working stroke, too little space will cause the pogo pin’s spring to be over-compressed and affect the service life. When it is 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 impact 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.
