1. Raw material preparation: Select high-purity tungsten material as the raw material to ensure the purity and performance of the electrode.

2. Material processing: Tungsten materials are processed into electrodes of the desired shape and size through processes such as hot processing, cold processing, and precision machining.

3. Surface treatment: Surface treatment of electrodes, such as polishing, sandblasting, or coating, to improve the smoothness and corrosion resistance of the electrodes.

4. Inspection and testing: Conduct quality inspection and performance testing on the produced tungsten electrode to ensure that it meets the requirements.

5. Packaging and delivery: Pack qualified tungsten electrodes and deliver them according to customer requirements.

Tungsten needles with pointed tips are mainly used for instrument probes. Like a digital four probe tester, this device is a multi-purpose comprehensive measurement device that utilizes the principle of four probe measurement.

This instrument follows the national standard for physical testing methods of monocrystalline silicon and refers to American A S. A specialized instrument designed according to the T.M standard for testing the electrical resistivity and block resistance (thin layer resistance) of semiconductor materials.

Suitable for testing the resistance performance of semiconductor materials in semiconductor material factories, semiconductor device factories, research institutions, and higher education institutions.
