EddyCus® TF map 2525 Series – Non-contact Sheet Resistance, Metal Layer Thickness, Resistivity and Electrical Anisotropy Mapping Device
The EddyCus® TF map 2525 Series automatically images characteristics on samples up to 250 x 250 mm² (10 x 10 inches) in non-contact mode. Upon manual sample positioning the device automatically measures and displays the distribution of properties across the entire sample area. The measurement settings allow easily and flexibly to choose between fast measurement times of below 1 minute or high spatial measurement resolution of more than 50,000 measurement points per sample. The resulting mapping provides a true insight to homogeneity and quality of transparent and non-transparent layers or wafer and metal sheets. The bench-top device allows depending of its setup the precise imaging of sheet resistance, metal thickness or optical transparency.

EddyCus® TF map 2525RM – Conductivity Mapping and Defect Identification in Thin Films
A variety of materials characteristics determine the conductivity of materials. Next to its composition also its structure and its purity affect the conductivity. The EddyCus® TF map 2525RM is an eddy current mapping system dedicated to high-resolution imaging of conductivity and correlated characteristics exposing material properties, effects and defects. The system can be equipped with various EddyCus sensors for conductivity imaging in high resolution or high penetration and defect detection by use of differential probes.

EddyCus® TF map 2525A – Non-Contact Electrical Anisotropy and Sheet Resistance Imaging Device
The EddyCus® TF map 2525A (Anisotropy) is a unique anisotropy imaging system providing spatially resolved anisotropy images for profound understanding of the dominant orientation in wire structures. It utilized eddy current sensors that induce currents into defined directions. The resulting image shows the dominating wire direction, the anisotropy strength and the resulting sheet resistance. This unique tool is valuable for the characterization of wire structures such as Silver Nano Wires (Ag-NW), CNT, metal grids or nano-rod structures. Intentional anisotropic nanowires provide a better sheet resistance to optical transparency performance compared to isotropic nano-wire electrodes with opposite contact structure. This non-destructive testing method saves time and ensures that the wire deposition process provides the required orientation and resistance. This tool can be applied for quick quality checks or systematic quality assurance.
Terms and concept
- “Sheet resistance anisotropy” refers to a difference in electrical resistivity measured parallel and perpendicular (traverse) to the machine direction
- Many wire and mesh structures can have an anisotropic sheet resistance
Electrical anisotropy…
- …can be optimized according to the layout of the contact pattern
- …can save material and improve optical transparency to sheet resistance ratio
