A test probe is a small tool used for testing and measurement, typicallyFormed by precise instrument riveting and pre pressing of three basic components: needle, needle tube, and spring.Plays a role in connecting and conducting signals in electronic testing.One end of the probe contacts the object under test, while the other end is used to conduct signals and transmit current.

Select the appropriate probe type and specifications based on the physical and chemical properties of the tested object, such as hardness, conductivity, size, etc.

Clarify the specific testing requirements, such as measurement accuracy and testing purpose (aging testing/functional testing), to determine the functionality and performance requirements of the probe.

Select the appropriate probe head type based on the shape, size, and spacing of the measured points. For example, when testing dirty surfaces, it is required that the needle tip has high penetrability, and a pointed probe can be chosen; For testing smaller planes, multiple points of contact with the tested object are required. For good contact, special shaped probes such as small four claw heads should be selected.

‌●Cleaning probeThoroughly clean the probe with appropriate cleaning agents and tools to ensure that there is no dust, dirt, or residue. This helps to avoid errors during the measurement process.

● Connect testing instruments/Insert the circuit to be testedConnect the probe to the testing instrument to ensure a stable and reliable connection between the probe and the testing instrument. Insert the other end of the probe into the circuit to be tested. During the insertion process, pay attention to whether the contact point of the probe is aligned with the measured point, and gently apply pressure to ensure good contact.

‌‌●Accurate contact‌：Accurately contact the probe with the designated position of the object being measured. For small measurement points, it may be necessary to use a microscope or magnifying glass to assist in positioning. Ensure good contact between the probe and the object being measured to avoid measurement errors caused by poor contact.‌

‌‌●Check the status of the probeCarefully inspect the probe for signs of wear, bending, or damage. Any physical damage may affect the performance of the probe and the accuracy of the measurement results.

‌●‌Record dataTimely record measurement data and ensure the accuracy and completeness of the data. Electronic recording devices or paper record forms can be used to record data for subsequent analysis and processing.

Test probes, as precision measuring tools, require proper maintenance and upkeep. Here are some suggestions:

●‌‌Regular cleaningRegularly use appropriate cleaning agents and tools to clean the probe, keeping its surface clean and smooth.

●‌‌Select probe recommended itinerary:Using probe recommended travel to test products can maintain design characteristics and testing performance under the recommended travel, resulting in good testing yield. However, many customers often resort to poor operation due to excessive travel pressure to enhance puncture performance, which can shorten the lifespan of the probe spring and even cause plate sticking.

●‌‌Create a good testing environment：Probes are used to test most circuit boards, and due to the precision of the tested object, testing probes are also manufactured into high-precision products. We need to create a clean and dry testing environment. similarChinaThe humid environment in many coastal areas can accelerate the oxidation of the probe. Xiandeli recommends customers to test the environment by controlling temperature and humidity.

As an important tool in the field of measurement, the correct use of test probes is crucial to ensure the accuracy and reliability of measurement results. Xiandeli will continue to explore and innovate, contributing its own strength to the application and development of testing probes.
