Customized picoamp level current test probe hot and cold bench for on-site testing
Wuhan Congtical Technology Co., Ltd. specializes in the field of thermal analysis. It has a variety of patented technology products such as probe hot and cold stages, spectrometer hot and cold stages, microscope hot and cold stages, in-situ stretching/compression hot and cold stages, heating plates, and variable temperature Test systems for resistance, dielectric temperature spectrum, Hall effect, etc.
Recently, according to customer needs, Wuhan Congtical customized picoamp level current testing hot and cold benches for on-site testing. Wuhan Chongguang picoamp level current probe hot and cold bench is a product designed to test the electrical properties of electronic components under changing temperature conditions. It can characterize the characteristics of the electrical properties of electronic components as they change with temperature during the heating and cooling processes. .
Congtical customized picoamp level current probe hot and cold stage has two types of probes, a bottom spring round probe that can be used to test the current through the sample, and a pointed probe with an adjustable probe arm It can test the picoamp level leakage current when the sample is energized. This custom-made picoamp level current probe hot and cold stage uses liquid nitrogen refrigeration, resistance heating, and vacuum insulation to achieve precise control within the range of -190~300°C. It can be integrated with electrical instruments (such as source meters) to perform temperature changes. Electrical performance testing.
