Patent ID: 8624612

Claim:
A measurement system for testing a resistive film, the system comprising: a stationary first micro-waveguide; a stationary second micro-waveguide with respect to the stationary first micro-waveguide and gaped away from the first micro-waveguide, the film being disposable between the first and second micro-waveguides wherein the first and second micro-waveguides are spaced away about 0.030 inches to about 1 inch away from each other; a first spool rotating to unwind a roll of the film between the first and second micro-waveguides; a second spool rotating in sync with the first spool to rewind the roll of the film received from between the first and second micro-waveguides, one of the first and second micro-waveguides, one of the first and second spools rotating under power of a motor; a network analyzer in electrical communication with the first and second micro-waveguides for measuring S parameters of the film wherein the measured S parameters of the film are converted to a sheet resistance value to determine whether the sheet resistance of the film is within tolerance.
