IEC TR 62899-402-4:2021

IEC TR 62899-402-4:2021(E), which is a Technical Report, is a preparatory work for the documents dealing with the measurement method of the vertical direction (surface forms) of printed patterns made by printed electronics technology.
The printed pattern of interest in this document is limited to straight lines on substrates with a flat surface. This document focuses on the classification and measurement methods for surface forms from the nanometer scale to the micrometer scale, and suggests the strategy for the subsequent documents.
