The resistance of a thin film coating is directly proportional to the resistivity and is an important Quality Control component of a coating. Therefore, resistivity may be the largest single item to determine the repeatability and function of a coating. Sheet resistance has the units of ohms, but it is convenient to refer to it in ohms per square since the sheet resistance produces the resistance of the coating within any square area. This parameter is therefore measured using the 4-point technique. Pocket Size Protection for Production, and Quality Assurance personnel who must know their products are "coated" properly.
