Description

[0002] PCB (Printed Circuit Board) test probes are devices used to test connections, components, and circuits on circuit boards. These tests are usually performed at different stages of the manufacturing process or during maintenance to ensure the functionality and quality of the circuit boards. The performance of the test probes is critical to the accuracy of the test results. Over time, the tips of the probes may be affected by contamination, oxidation, or other contaminants, which may cause a decrease in test accuracy. Using a cleaning device can remove these contaminants and ensure that the test probes maintain good performance. The cleaning device helps maintain the consistency of the test probes. If there are uneven contaminants on the probe surface, contact at different test points may cause differences in test results. By using a cleaning device, it can be ensured that the probes have a similar cleaning state at different test points to maintain test consistency.
