Convenient and rapid 4-wire method electrode pressing method

Abstract

The invention discloses a convenient and rapid 4-wire method electrode pressing method which comprises the following steps of preparing a platinum wire and a sample tray, sticking and taking Ag glue with a clean toothpick, dispensing the Ag glue on a sample and an electrode on the corresponding sample tray respectively, then gluing up one end of the platinum wire with the toothpick adhered with the Ag glue, putting one end of the platinum wire in the Ag glue on the electrode on the corresponding sample tray, then continuously putting the other end of the platinum wire in the Ag glue on the sample with the toothpick adhered with the Ag glue, and finally treating the two ends of the platinum wire with the toothpick adhered with the Ag glue to enable the two ends of the platinum wire to be completely covered with the Ag glue on the electrode and the Ag glue on the sample respectively. The convenient and rapid 4-wire method electrode pressing method provided by the invention is simple in required equipment and operation process, lowers the sample preparation difficulty, improves the sample preparation efficiency, reduces occurrence of damage condition of an expensive metal wire, savesthe cost, ensures the quality of a prepared test sample and provides guarantee for physical property measurement of the sample to obtain an accurate experimental result.

Description

technical field [0001] The invention belongs to the technical field of measurement methods for physical properties of materials, and in particular relates to a convenient 4-line piezoelectric method. Background technique [0002] The multifunctional physical property measurement system PPMS is widely used in many scientific research fields such as physics, chemistry, and material science. It is found in almost all first-class related laboratories and is playing an increasingly important role in physical property measurement. Now it has become a conventional physical property measurement tool. However, in the process of sample preparation piezoelectric electrodes for physical property measurement, very sharp tweezers are usually used as a carrier to remove the metal wire. The pinching or bending of the pinch will bring great inconvenience to the measurement of physical properties, and will waste a lot of manpower and material resources. Therefore, it is necessary to explore ...
