ICT test probe plays a very important role in the ICT test process. Although the probe is a consumable material, if it is well maintained, the life growth of the probe has a certain effect on the cost control. How to maintain the test probe and make it last longer, here are the five key points of probe maintenance:

1. Test environment The test environment is the main reason for the probe to be contaminated with sundry objects. For example, if the test environment has a lot of flux or there is a lot of dust in the air, the probe will be contaminated, causing the contact problem of the probe. Therefore, a high standard dust-free workshop is one of the prerequisites to ensure the life of the probe.

2. Dust jacket Many fixture factories provide dust jacket to prevent dirt from falling on the test probe and probe tube. Especially empty or unused fixtures. In a vacuum fixture, dust will settle around the test plate and when using a vacuum gauge will be sucked directly into the test probe.

3. Process control When testing PCB with a lot of rosin, the probe will be contaminated with a lot of rosin, so it is very important to control the amount of rosin well.

4. Wipe the use of anti-static brush is a safer and faster method, metal brush or hard brush may damage the probe or coating, causing adverse effects on the test results.

5. Probe head Probe head is easy to be contaminated by flux or rosin, it is recommended to use a soft brush to clean. First, pull out the test probe from the fixture and tie it together. Then, only partially soak the probe in detergent for about five minutes, wipe with a soft brush, remove the residue to dry, and install to continue the test. Keeping the test probe in a clean state is a more effective way to reduce the test failure rate.
