Why do test probes always burn out?

Test probes can burn out for a variety of reasons,probe test system here are some common ones:

1. overload: test probes may be subjected to excessive current or voltage during testing, which exceeds their capacity and burns out.

2. overheating: the test probes may get hot during the testing process, if there is no good heat dissipation system or the testing time is too long, the temperature may exceed its tolerance range and burn out.

3. poor contact: if the test probe and the equipment under test contact is poor, may lead to arc discharge,RF probes resulting in damage to the probe.

4. Corrosion: Test probes may be corroded due to contact with some chemicals, resulting in burnout.

5. mechanical damage: test probes may suffer mechanical damage during testing, such as being crushed or broken.

To solve the problem of burnt out test probes,probe card the following measures can be considered:

1. Ensure that suitable test probes are used and that test voltages and currents do not exceed their tolerance limits.

2. Ensure good contact between the test equipment and the test probe to avoid damage caused by poor contact.

3. ensure that the heat dissipation and protection system of the test probes are in good working condition to avoid damage caused by overheating.

4. avoid contact with chemical substances to avoid corrosion.

5. use appropriate mechanical protection measures to avoid mechanical damage.
