etching procedure; this is particularly true of closely spaced electrodes on the same surface when the property to be measured depends on the electrode geometry. Second, electrical conductance in the material, particularly surface conductance, may be affected by the chemicals used to etch the copper, the length of time of etching, and the manner in which the specimen is cleaned after etching.
This practice standardizes the etching procedure in order to provide a basis for comparison of electric
