The impact of accuracy on the performance of the Pogo pin connector

　　Due to the development of smart phones and smart wearables, electronic products are being developed in the direction of lightness, thinness and compactness, making the originally limited space smaller. In order to meet the needs of the market, the Pogo pin connector is now getting smaller and smaller, and its accuracy requirements are getting higher and higher.

　　The accuracy of 5G RF pogopin connectors processed by different processing equipment will definitely be different. So, what impact will the processing accuracy have on the performance of the Pogo pin connector?

　　1. The surface of the high-precision Pogo pin connector has a very high finish. In fact, the finish has no great effect on the outer surface of the needle tube. The inner wall has a greater impact. If the surface is very rough, it will cause the Pogo pin to expand and contract. At the time, the friction coefficient will be increased, which will cause the phenomenon of lag. Not only that, when the friction coefficient is too large during work, it will seriously affect the wear of the outer wall of the Pogo pin needle and the inner wall of the needle tube, thereby greatly reducing the service life of the Pogo pin connector.

　　Second, the size error of Pogo pin products is affected, and the products processed by low-precision equipment will have large size deviations, which will bring great troubles to the later assembly and application.
