The rise of smart wearables and the increasing demand for high current connectors due to the rapid charging of smartphones have led to more frequent applications of spring POGO PIN probe connectors. Currently, most smart digital products on the market use spring POGO PIN top pin connectors, with only some low-end products still using spring type connectors.
Today, Yongtan Electronics editor will take you to explore the precautions that should be taken when selecting and applying spring POGO PIN top probe connectors to products.
1、 Selection of working stroke for spring POGO PIN probe connector
When choosing a spring POGO PIN probe connector, it is important to consider the space of the product being used and select one within the working stroke range; Small space can cause excessive compression of the spring of the POGO PIN top pin connector, affecting its service life. Large space may result in inadequate contact, unstable impedance, and transient breakage.

2、 Selection of Electroplating Materials
Electroplating materials have the functions of increasing conductivity, preventing oxidation, and resisting wear in spring POGO PIN top pin connectors. Different materials have different effects, such as gold, which has good conductivity. For high current connectors and products with high impedance requirements, electroplated gold is generally chosen.
3、 The influence of electroplating film thickness
The spring POGO PIN top pin connector will experience certain friction during operation due to the need for contact. Over time, it will wear out, and the thickness of the electroplating film will have a significant impact on the product's service life. When used to a certain extent, the electroplating layer will be worn off, which may result in excessive resistance, unstable impedance, and other phenomena. The electroplating layer of Pogopin with 100000 cycles is definitely thicker than that with 10000 cycles, so please be sure to choose the electroplating film thickness according to your needs when selecting products.
4、 The influence of elasticity
The contact force of the spring POGO PIN top pin connector comes from the internal spring, and the magnitude of the spring force can directly affect the impedance and stability of the spring POGO PIN top pin; Excessive elasticity will increase the friction coefficient and affect the service life of the spring POGO PIN ejector pin.
