R50/R54-Series Sheet Resistance Mapping

R50/R54-Series Sheet Resistance Mapping The 4PP contact four-point probe configuration is recommended for thin metal and ion implant layers, and the non-contact Eddy Current (EC) probe is recommended for thicker metal layers and soft or flexible conductive surfaces Measurement Range 1mΩ/sq - 200MΩ/sq/ 1mΩ/sq - 50Ω/sq
