OEM Beryllium Copper Precision Springs For Probe

The spring probe needle material is generally selected as Becu or SK. Both have advantages and disadvantages. Becu has good conductivity, but lacks hardness, and SK has high hardness, but it is easy to rust. The choice of spring probe spring material is also more important. SUS SWP, especially now more and more PB free products, directly lead to the pins or BGA solder balls becoming soft or hard. During the test, it was found that the original The yield is very high. After changing the solder ball or lead material, the yield 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 work of the spring probe. life. Today, Spring Home Jinxi Spring takes us to understand what are the advantages of high-quality probe springs?

  1. Good contact reliability: The spring probe has a larger amount of compression than the shrapnel connector of the same size, and the contact is more stable. When it is strongly impacted by external force, the spring pressure change of the spring probe is relatively small.
  2. It can effectively save the space of the PCB board: under the same amount of compression, the spring probe takes up less space than the shrapnel connector.
  3. The contact point is more stable: the contact point of the spring probe does not move when it is compressed, while the shrapnel connector will move relatively. The stable contact point can make the product obtain stable electrical performance and better exert the performance of the product .
  4. Longer service life: The spring probe can be retracted at least 10,000 times, and the spring probe with better quality can be retracted more than 100,000 times, which also makes the service life of the product longer.
  5. The production speed is fast and the cost is low: the spring probe does not require mold opening and stamping, and the development sample and mass production time is short, so the spring probe is a more economical and faster connector selection method. With the continuous development of the industry, the products that precision springs are in contact with us are appearing more and more frequently. So what is the main function of precision springs?
  6. Control the movement of machinery, such as valve springs in internal combustion engines, control precision springs in clutches, etc.
  7. Absorb vibration and impact energy, such as buffering precision springs under automobiles and train carriages, vibration-absorbing precision springs in couplings, etc.
  8. Store and output energy as power, such as precision springs in precision springs of watches and clocks.
  9. Used as a force measuring element, such as a force measuring device, a precision spring in a precision spring balance, etc. The ratio of the load to the deformation of the precision spring is called the spring stiffness. The higher the stiffness, the harder the precision spring. Precision spring is an elastic element widely used in the mechanical and electronic industries. Precision spring can produce large elastic deformation when loaded, convert mechanical work or kinetic energy into deformation energy, and the deformation of the spring disappears and returns to its original state after unloading. , which converts deformation energy into mechanical work or kinetic energy.
