Scope
This document describes the method of measuring the thickness of gold coatings in various gold products using a scanning electron microscope (SEM).
This document is applicable to the measurement of gold coatings with thicknesses ranging from 25 nm to 50 μm. For gold coatings with other thicknesses, refer to the corresponding measurement procedures.
Note: The minimum thickness that can actually be measured is affected by factors such as the image resolution and magnification of the SEM, the performance of the equipment, the sample preparation techniques, and the conductivity of the sample.
