How should the test probe be maintained?

How to maintain the ICT test probes in the test fixture? Nowadays, the test probes are widely used by users, and various problems will inevitably occur. Then, Huaronghua Electronics will tell you how to maintain the test probes:

1. Clean test needle: Keeping the test needle clean is the most effective way to greatly reduce the failure rate.

2. The needle of the test needle: There are some situations where it is not only necessary to clean with a brush, so using other types of solvents or cleaning agents will be the last alternative. The recommended method is to simply clean the needle, remove the test needle from the jig, bundle it together and soak the needle in a shallow detergent for about five minutes, rub it with soft hair, remove the residue, and then dry it. , So you can install it back to continue testing.

3. Dust cover of the test probe: Many fixture factories will provide a dust cover to prevent empty dirt from falling on the test needle and needle tube. In a vacuum fixture, dust is easy to fall into the test. needle.

4. Dirt cleaning of the test needle: In order not to affect the contact surface of the test needle tube and the inner wall of the test needle, resulting in an excessive increase in impedance, it is best not to use solvent to clean the test needle or use solvent immersion to clean the dirt.

5. Environmental maintenance of the test probe: The test environment is the main factor that causes the test needle to be dirty. Airborne pollutants such as dust will fall on the needle and cause contact problems. Therefore, we need to maintain the environment of the test needle.

Let's talk about the benefits of gold-plated spring current charging pins

The electroplated layer on the surface of the spring current charging pin not only protects the connector, but also improves the performance of some aspects. The electroplated layer is the protector of the normal use of the connector.
