The first domestic innovative product Bailibo high-temperature four-probe measurement system is suitable for scientific research departments of manufacturing enterprises, colleges and universities to more conveniently study the electrical properties of semiconductors under variable temperature vacuum and atmosphere conditions.
Measurement range: Resistivity of silicon germanium single crystal ingot wafer, measurement of sheet resistance of silicon epitaxial layer diffusion layer and ion implantation layer, and measurement of sheet resistance of conductive glass and other conductive films.
Block resistance allows measurement conditions such as high temperature, vacuum atmosphere and other conditions.
Measurements can be made under normal temperature, variable temperature and constant temperature conditions.
Enabling analysis software design, input the sample area and thickness to automatically calculate the resistivity of the sample.
Analyze the change curve between resistivity and temperature, and can be matched with or digital multimeter.

Temperature test
During the design and finalization of electronic products, in order to prevent the surface temperature from being too high to harm the user or the temperature exceeding the limit of the material. To avoid the risk of fire, insulation failure and electric shock caused by the withstand limit value, the temperature of each part of the equipment needs to be tested under normal operating conditions and simulated fault conditions. Currently, thermocouple measurement or additional infrared temperature measurement monitoring is generally used.
