SEPTEMBER 2019 I PCB007 MAGAZINE 87 scanned to characterize the width, height, cross-sectional area, and surface roughness of conductor traces (Figures 6 through 16). The scan was performed with a table-top scanner. A line confocal sensor mounted on the pro - duction line can capture similar 3D profiles from a moving surface for automated real- time analysis. Figure 5: Scanned area with fine lines. Figure 6: 2D pseudo-color view of the scanned area. Figure 7: 3D view of the surface. Figure 8: Zoomed-in 3D view of the surface. Figure 9: Extracting a cross-sectional profile. Figure 10: Trace width measurement at the top from the extracted profile.
