The working principle of the gold-plated tungsten-rhenium probe is to realize the transmission and control of electrical signals through the contact between the probe needle and the circuit under test. The gold-plated layer on the surface of the gold-plated tungsten-rhenium probe has good conductivity and corrosion resistance, which can ensure stable performance during long-term testing. At the same time, the gold-plated tungsten-rhenium probe is precisely ground and polished during the manufacturing process to ensure that the contact area and contact resistance with the circuit under test meet the test requirements.
When the gold-plated tungsten-rhenium probe contacts the circuit under test, the contact resistance will change with the change of the contact area and pressure between the probe needle and the circuit under test. These changes will affect the transmission speed and stability of the electrical signal, thereby affecting the test results. Therefore, the gold-plated tungsten-rhenium probe needs to have the characteristics of high precision and high stability to ensure the accuracy and reliability of the test results.
