　　Which industry products need to use POGO PIN connectors?

　　Pogo pin is a precision connector used in electronic products such as mobile phones. It is widely used in the connection between mobile phone antennas, mobile phone batteries, etc. and mobile phone motherboards. There is a precision spring structure inside the pogo pin.

　　The surface of the product is generally gold-plated, and the unit price of the product is generally about 5 to 1 yuan.

　　There are roughly three parts to the pogo pin.

　　Needle, spring, needle tube

　　The needle and material are generally selected as Becu or SK. Both have advantages and disadvantages. Becu has good conductivity, but lacks hardness. SK has high hardness, but it is easy to rust.

　　Springs are also more important. SUS SWP, especially now that there are more and more PB free products, directly causes the pins or BGA solder balls to become soft or hard. During the test, it was found that the original yield rate was very high. After changing the solder ball or lead material, the yield rate is extremely poor. The choice of spring pressure is very important. The test environment has very strict requirements on the material of the spring. The high and low temperature test directly affects the working life of the probe.

　　There are many materials for needle tube and selection, and PB materials are generally used.

　　The main reason for the low yield may be due to the increase in impedance during the test of the probe.

　　The increase in impedance is mostly caused by the wear of the needle during the test, the damage of the coating, and the tin hanging of the needle.
