Google Patents US20020074640A1 - Semiconductor test socket having pogo-pin contacts Beryllium copper wire has the highest life under the same specifications, but the elasticity is the smallest.US20020074640A1 - Semiconductor test socket having pogo-pin contacts Carbon steel wire (piano wire) have the highest elasticity under the same specifications, but the life is short. ![]() All above materials can be CNC, cam machine turning.Ĭommon materials for Pogo Pin spring, SUS304 is the most comprehensive cost-effective, and under the same specifications, the comprehensive performance of elasticity and life is the highest. ![]() Selective quenching is an option, but it will affect the cost of the whole product.Ĭommon materials for Pogo Pin plunger,the basic material selection is similar to that of the barrel. The only difference is that the plunger can be made of materials with ultra-high hardness, such as SK4, we choose it as the plunger because it has better hardness and is also conducive to turning processing, it is a good option for plunger head protection, it requires heat treatment to achieve a hard structure and maintain the integrity of the tip. ![]() Usually the barrel is not heat treated because the barrel needs to be bent during the assembly. Phosphor bronze is selected for the use of some high-frequency signal transmission products. The structure of pogo pin includes plunger, barrel and spring,the materials chosen for the three parts are different.Ĭommon materials for Pogo Pin barrel, the cost of brass is relatively low, beryllium copper has excellent electronic properties and low impedance. ![]()
