The salt spray test can be used to evaluate the ability of the pogo pin coating to resist salt spray corrosion. And the electrochemical corrosion that may occur on the surface treatment layer of the metal structural parts and contact parts of the pogo pin when working in an environment containing moisture and salt.

The pogo pin salt spray test is generally 24H, 48H, 72H, 96H and higher standards. The results of the salt spray test are affected by two factors: raw materials and coating. Therefore, the following measures can be taken to improve the results of the salt spray test for these two factors:

  1. Raw materials: Stainless steel or alloys with strong corrosion resistance can be used as raw materials. These materials show good corrosion resistance in salt spray tests.
  2. Coating: Thickening the coating or multi-layer composite coating can be used to improve the results of the salt spray test. These measures can enhance the corrosion resistance of the product and increase the service life of the product.

In summary, the use of appropriate raw materials and coating design is the key to improving the results of the salt zero test. Through the above measures, the salt spray test resistance performance of the pogopin connector can be effectively improved to ensure its reliability and stability in harsh environments. It is recommended to screen and design materials and coatings before conducting salt spray tests to ensure the reliability of test results and improve their salt spray resistance.

In addition to the above two aspects, to improve the salt spray test resistance of pogo pins, you can also start from the following aspects:

  1. Control test conditions: The conditions of salt spray tests have an important influence on the results. According to the standard, the salt water concentration is usually 5%, the laboratory temperature is 35℃, the relative humidity is 85%RH, and the test time is 48 hours or longer. Ensuring strict control of these conditions helps to accurately evaluate the corrosion resistance of connectors.
  2. Improve design: Consider the structure and layout of the connector in the design stage to avoid excessive exposure of metal parts and reduce the corrosion area. For example, adopting a sealing design or adding a protective coating can further improve the connector’s tolerance in harsh environments
  3. Regular maintenance and cleaning: During use, regularly clean dust, oil and other pollutants on the surface of the connector to prevent these substances from accelerating the corrosion process. In addition, avoid excessive mechanical pressure and improper operation to reduce mechanical damage and surface contamination.

Through the above measures, the corrosion resistance of the pogo pin connector in the salt spray environment can be effectively improved, ensuring its stable operation in an environment containing moisture and salt.
