How to properly use and clean the test probe correctly to maximize the life span?
1. The main factors affecting the service life of the probe
Whether the stroke of the test probe is overvoltage, whether it has lateral force intervention, whether the passing test current exceeds the rated value, etc.
2. How to use it to maximize the life of the probe
The test probe is used according to the recommended usage stroke, to ensure that the probe is vertically stretched on the device, and does not pass the amount of current, to ensure that the device is clean and dry, etc.;
3. If the service life exceeds 1 million times, what will be the impact?
At present, only three conventional probes (GKS-050/075/100) of the ICT series can have a mechanical service life of 100w times, but this is not the actual service life, but the mechanical service life of the spring. It is usually recommended that the probe must be replaced after 30W use. Since the inside of the probe is gold-plated, the gold-plated layer will fall off after long-term use. The most direct manifestation is that the probe impedance becomes higher, which is very important for the stability of the test results. Big impact.
Contaminants will enter the needle body when the test probe is moving and adhere to the spring. Some contaminants will corrode the spring, some contaminants will stick to the spring, and some contaminants will accumulate in the middle of the spring's turns and prevent the spring from contracting. After contaminants accumulate for a period of time, they will cause irreparable damage to the spring. Therefore, if you want to increase the service life of the probe, you can refer to the following points for improvement:
1. Clean the contaminants on the probe head regularly. Use a dry electrostatic brush when cleaning, with the needle tip parallel to the ground
2. Ensure that the measuring point is clean, and do not leave too much rosin, flux, etc.
3. The test probe should be used with the correct stroke and cannot be over-voltage
4. The temperature of the application environment of the test probe cannot exceed the set value of the probe
5. During the testing process, the test probe cannot have lateral force involved
6. The current tested by the test probe cannot exceed the rated value
7. When the test probe is maintained on the equipment, it is best to use professional tools
