Whether the material of the Pogo Pin is correct plays a key role in intelligent equipment. Here are some things to consider when choosing a Pogo Pin model.

  1. Planning the route for Pogo Pin work

When choosing a Pogo Pin, it should be based on the indoor space of the product that will be used and fit within the work schedule. If the indoor space is too small, the spring of the Pogo Pin will shrink too much, which will shorten its life. If the indoor space is too large, the spring of the Pogo Pin will shrink too little, which will shorten its life. The touch will be delayed if it’s too big, leading to unbalanced characteristic impedance and a sudden stop.

  1. Materials for plating

Electroplating materials make Pogo Pins more conductive, stop air from oxidizing them, and make them less likely to wear out. However, the effects of different raw materials are different. For example, gold is a good conductor, so it is usually chosen for the electroplating process for high-current RF connectors and its products with high characteristic impedance.

  1. What harm does the layer made by the electroplating process do?

You often have to touch the Pogo Pin during work, which will cause damage after a certain amount of friction time. The thickness of the electroplating film will also greatly affect how long the product will last. For example, the electroplating process layer will be damaged after a certain amount of use. It will wear away, making the resistor too big and unstable with the characteristic impedance. For example, the electroplating process layer on the 100,000-time Pogo Pin is thicker than on the 10,000-time Pogo Pin. Therefore, when choosing the product model, it is best to choose the electroplating process regulations based on the needs.

  1. The Risks of Flexibility

The internal elastic force gives the Pogo Pin its contact force. The size of the elastic spring force can immediately damage the Pogo Pin’s characteristic impedance. If the elasticity is too big, it will increase the frictional resistance and shorten the Pogo Pin’s life.
