Recently, according to customer needs, test engineers conducted microscope adaptation tests and temperature control tests on the picoamp current 4-probe displacement hot and cold stage.

1. Product introduction

Congtical picoamp current 4-probe displacement hot and cold stage is a product designed for temperature-changing electrical testing in the material research process. It can characterize the heating and cooling stages of materials, test temperature-changing resistance, and the characteristics of electrical properties changing with temperature.

This model can perform high-precision XYZ direction displacement by adjusting the external probe arm and moving the internal probe position. In addition, 24 electrode lines are designed internally to facilitate connection with a variety of source meters for different types of electrical tests (such as dielectric tests). constant, ferroelectric constant, IV curve, variable temperature resistance, etc.).

The vacuum picoamp current 4-probe displacement hot and cold stage uses liquid nitrogen refrigeration and resistance heating to achieve precise control within the range of -190~500°C. It can be integrated with electrical instruments (such as source meters, multimeters, etc.) to perform temperature changes. test.
