PSM-PM Series

PSM-PM series permanent magnet low temperature probe stage is a probe stage developed specifically for low-temperature vertical magnetic field electrical test environment, providing 0.5T vertical magnetic field, able to 2 inch, 4 inch, wafer for repeatable, standard electrical experiments, external different test equipment can be completed on the device's electrical characteristics of the measurement, parametric measurements, DC measurements, RF measurements and Hall measurements. Permanent magnet low temperature probe stage PSM-PM series, specific parameters, please consult customer service!

PSM-PM Series Overview

With the continuous development of electronic technology, for precision micro (nano-scale) microelectronic devices, to test its electrical properties (such as current, voltage, impedance, etc.) in a low-temperature environment or a variable temperature environment, a cryogenic probe stage with a microscope can provide a good low-temperature electrical test environment.

Permanent magnet cryogenic probe stations play a vital role in scientific research and technology development. It is capable of performing various non-destructive physical and electrical property tests on samples at low temperatures, helping researchers to gain a deeper understanding of the physical and electrical properties of materials or devices, thus providing important data support for the development and application of new materials.
