Sheet Resistance (in ohms/square) via Eddy Current method

Overview

Sheet Resistance (in ohms/square) via Eddy Current method.  For over 40 years.  American Made.


  Products

  • RD200
    RD200 is our best-selling benchtop sensor for characterizing wafers. Measure sheet resistance, thickness, resistivity, emissivity, and much more....

  • FEATURE SUMMARY

    • Sensor with a 26 mm spot size,100 mm reach, and 200 mm x 200 mm stage
    • Noncontact measurement of sheet resistance, thickness, resistivity, and emissivity
    • Measures nearly all thin conductive materials or coatings (e.g. wafer, glass, roll to roll, etc.)
    • Small swappable sensor for benchtop or inline use
    • Add additional sensors, ranges, and stages any time
    • Simple one button operation with LCD
    • Intuitive software for benchtop, mapping, and inline monitoring applications
    • Interface via LCD, Modbus over Ethernet, or use our Python library

    APPLICATIONS—Designed for use on glass, wafers, film and more, including:

    • Touch screens, flat screens, ITO, TCOs, etc.
    • Carbon nanotube, graphene, silver nanowire, etc.
    • Semiconductor materials
    • Photovoltaic materials
    • Architectural glass (Low-E), smart glass
    • OLED and LED applications
    • Packaging, decorative films/paper, metalized labels, microwave susceptors, reflective materials
    • Flex circuitry and flexible circuit boards
    • Metalized capacitor foil
    • Low observables
    • Batteries and fuel cells
    • De-icing and heating products
    • Antennas
    • Anti-static films

    TYPES OF MEASUREMENTS THAT ARE POSSIBLE

    • Sheet Resistance in ohms/square
    • Sheet Conductance in siemens/square
    • Resistivity in ohms-cm
    • Thickness in microns
    • Emissivity between 0 & 1 as defined by user

    ADVANTAGES OF NONCONTACT EDDY CURRENT

    • Nondestructive
    • Reads through insulating layers
    • Measures moving material
    • Nearly instantaneous readings
    • Provides real-time process inspection

    REDUCE PRODUCT AND LABOR COSTS

    • Automate testing—no more manual probing
    • Test 100% of material without damage
    • Address coating issues as they happen
    • Avoid further processing of out-of-spec material
