Manual sheet resistivity measurement systems for laboratory, for research and small productions. The stand includes several features to ensure accurate resistivity measurements. The system is used to characterize materials made by semiconductor doping, metal deposition, resistive paste printing, glass coating…
A manual lever is used to make the Z movement to be in contact with the sample, with a repeatability in the order of one micron. In addition, a control wheel allows a fine” Z movement. The sample is mounted on a movable support, which makes it possible to be places under the four point probe head easily between each measuring point
The software manages the tests, displays results and allows printouts or export of the data. The user inputs the size and shape of the sample, edge exclusion and number of points to be tested. The user may also define pass/fail criteria and which parameter (Sheet Resistance, Resistivity, or V/I) to display. A graphic picture of the target probe points is displayed. Prompts tell user to move to the next position. Upon completion of testing all points, the average, standard deviation, minimum and maximum are prominently displayed. Upon completion, a summary report may be printed showing the data and pass/fail status.
