Warpage, Bow, and Flatness Measurement Selection Guide

This document provides a selection guide and measurement principles for warpage, bow, and flatness measurement using laser-based sensors. It covers methods such as moving a workpiece or sensor head, using 2D sensors, and employing multiple sensors, along with specific applications like measuring liquid crystal surfaces, chassis flatness, roller bow, board warpage, glass plate flatness, TAB tape warpage, vehicle body panels, wafer warpage, mirror-surfaced plates, and thin plates.
