How to use test probes correctly?

A test probe is an important tool used to test electronic equipment,wafer testing which is capable of detecting parameters such as current, voltage and impedance in a circuit. However, if the test probe is not used correctly, it may affect the accuracy of the test results or even damage the equipment. Therefore, you need to pay attention to the following points when using test probes:

1. The main factors affecting the life of the probe

-Whether the test probe travel is overpressurized: If the probe travel exceeds its rated range, it may result in bending or damage to the probe.

- Whether there can be lateral force intervention: During the test work, lateral force on the probe should be avoided, which may result in affecting the accuracy of the analytical test study results.

- Whether the test current passed is greater than the rated value: If the test current exceeds the rated value of the probe,wafer probe it may lead to overheating or damage of the probe.

2. How can I use it to maximize the life of the probe?

- Use the recommended travel: Select the appropriate travel for testing according to the probe's specifications and instructions to avoid overuse.

-Ensure that the probe telescopes vertically on the device: Keep the probe perpendicular to the surface of the device when inserting and withdrawing it to avoid tilted insertion or twisting.

- Do not pass the rated current: According to the rated current of the teaching equipment and the technical requirements of the test, choose an appropriate current can be analyzed and tested to avoid exceeding the rated value.

- Ensure the instrument is clean and dry: Before using the instrument, the surface of the instrument should be clean and dust-free, and should maintain appropriate humidity to avoid contamination of the probe.

3. What happens when the service life exceeds 1 million times? In what way?

Currently, there are only three conventional probes (GKS-050/075/100) in the ICT series that have a mechanical life of 1,000,000 times, but this is only the mechanical life of the spring. In fact, we recommend replacing the probes after 300,000 times as long term use may cause the gold plating to peel off and affect the stability of the test results.

Second, contaminants enter the needle when the test probe moves and can attach to the spring. Some contaminants will corrode the spring, some contaminants will stick to the spring, and some contaminants will build up between the turns of the spring and prevent it from contracting.probe holder The accumulation of these contaminants over time can cause irreparable damage to the spring. Therefore, in order to improve the service life of the probe, improvements can be made in the following areas.

1. Regularly carry out cleaning as well as the probe through the head of the contaminants: use different dry electrostatic brushes to clean the head of the probe to keep it clean. At the same time, when cleaning to keep the tip of the needle and the ground using parallel, to avoid scratching or damage to the electronic probe.

2. Ensure that the test point is clean: During testing, make sure that there is no excessive residue of rosin, flux, etc. These residues can affect the test results. These residues can affect the accuracy of the test results.

3. Use the correct stroke: According to the specifications and instructions of the probe, select the appropriate stroke for testing. Avoid overuse or underutilization.

Four. Control the temperature of the test environment: When using the test probe, ensure that the ambient temperature does not exceed the probe's set point. Excessive temperature may cause deformation or damage to the probe.

5. Avoid Lateral Force Involvement:Avoid applying lateral force to the probe during testing. Lateral force will affect the accuracy of the test results.

6. Control system test working current does not exceed the rated value: according to the rated current of the teaching equipment and test technical requirements, choose a suitable current can be analyzed test. Avoid exceeding the rated value resulting in overheating or damage to the probe.

Seven. Use professional tools for maintenance: When maintaining the test probes, try to use professional tools. This ensures the safety and accuracy of the maintenance process.
