1. Selection of working stroke of pogopin connector:
When choosing a POGOPIN connector, it must be determined according to the space of the product used, and the selection is within the working stroke range; if the space is too small, the spring of the POGOPIN connector will be over-compressed, which will affect the service life, and if the space is too large, it may cause contact If it is not in place, the impedance is unstable and the transient is broken.
2. Selection of electroplating materials for pogopin connectors:
Electroplating materials have the functions of increasing conductivity, preventing oxidation, and anti-wear in pogopin connectors. 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.
3. The influence of the plating film thickness of the pogopin connector:
The pogopin connector will have a certain amount of friction due to the contact during operation. It will wear for a long time. The thickness of the plating film will have a great influence on the service life of the product. When the use reaches a certain limit, the plating layer will be worn away. , there may be phenomena such as excessive resistance and unstable impedance. The electroplating layer of 100,000 times pogopin is definitely thicker than that of 10,000 times, so please be sure to choose the electroplating requirements according to your needs when selecting products.
4. The influence of the elasticity of the pogopin connector:
The contact force of the pogopin connector comes from the internal spring. The size of the spring elastic force can directly affect the impedance of the pogopin, how stable it is, and if the elastic force is too large, it will increase the friction coefficient and affect the service life of the pogopin.
