How to choose the material of the probe connector?Bending needle series Vendor(图1)

  Probe type connector is a kind of precision connecting device used in electronic products. It is mainly composed of three basic parts: spring, needle and needle tube. They are formed by the riveting of precision equipment. Probe. It has the characteristics of high work efficiency, stable telecommunications transmission, low resistance and low manufacturing cost. It is widely used in semiconductor equipment to play a role in connection. Many friends do not know how to choose the material of the probe type connector. Today, Sunpak Technology will give you a specific introduction.

  Usually, the material of the needle of the probe type connector is SK or Becu. The two are somewhat different, each has its own advantages and disadvantages. Among them, SK has higher hardness, but it is very easy to rust, which is a bit more troublesome; while Becu has better conduction performance, but its hardness is not very good. Therefore, when you choose, you must measure it to see which material is more effective, or choose under the suggestion of the pogo pin manufacturer.

  The selection of the needle tube material of the probe connector is also very important. There are many materials to choose from, but everyone usually prefers to choose the PB material. In addition, when choosing spring materials, be careful not to choose randomly. Because the test environment has very strict requirements for spring materials, if high temperature or low temperature tests are performed, it will directly affect the service life of the probe connector. Now there are more and more products of PB free, which directly lead to the hardening or softening of the pins.

  During the test, if the yield rate is found to be low, it may be caused by the relatively large impedance of the probe connector. If the yield rate is very high, and the yield rate becomes very poor after replacing the pin material, it may be Caused by the pressure of the spring.
