Test Pin Repelling Coating


When impurities attack semiconductor test pins, their performance is certain to suffer. Alfa Chemistry can assist you in preventing this issue in the first place. The use of test pin repellant coatings in test pin applications has a number of advantages in terms of performance.

We have a specific surface coating method that allows us to functionalize semiconductor spring test pins to prevent tin oxide build-up and other impurities. The test pin's life is considerably extended by slowing the formation of tin oxide semiconductors. Our ultrathin coatings have been proved to have no effect on electrical conductivity. In addition, semiconductor test pin handling technology can be used in a number of liquid phase applications.

Why Do You Need A Test Pin Repelling Coating?

Resistant coatings created for test pins can successfully repel tin oxide and other contaminants on semiconductor test pins. The use of a test pin to repel the coating can greatly improve product quality. The following are some situations in which you might need to use our test needle repellent coating.

  • For as long as possible, you want to maintain the test needle as clean as possible.
  • You want to avoid getting erroneous results from tainted test needles.
  • The contamination of your product's surface with tin oxide contaminants is continuously rising.

Suitable Test Pin Repelling Coating Solution

Often Semiconductor customers expect their test pins to remain functional for long periods of time without failure without frequent cleaning. Alfa Chemistry's test pin protective coatings can help effectively prevent contamination of test pins for electronic components such as PCBs, semiconductors, etc.

Our technology is a liquid phase that can be applied to any metal, including gold, copper, nickel, and stainless steel, using a variety of methods. The main cause of resisting test pin failure is tin oxide. Tin oxide levels on test probe pins are greatly reduced by our test pin repellant coating. The test needle's life is substantially extended by functionalizing its surface against water, oil, and other pollutants. Tin oxide on functionalized test pins is reduced by a factor of 5 compared to untreated test pins, according to experiments.

In addition, Alfa Chemistry's test pin repellent coatings help keep semiconductor-critical equipment performing well without extensive and expensive cleaning or replacement.
