The VK-9700 Color 3D Laser Scanning Confocal Microscope has the capabilities of SEMs and non-contact profilometry. Features are said to include 18,000x magnification and 0.001 µm precision. Performs surface profile, roughness, 3D and comparative measurements. 3D display works with the virtual trackball method and a computer mouse to control viewing angle, lighting angle, zoom level and Z-axis height. 3D images can be illuminated with pseudo-light. VK-Viewer, VK-Analyzer and VK-Assembler are available software programs. An optional adjustable stand permits measurement of objects up to 3.94". Larger stages for wafers up to 11.81", electric stages for automatic image assembly, and a separate measuring head are available.

Laser cut stencils are said to deliver aperture definition and superior dimensional tolerances for pitch apertures down to 0.016". On a 600 x 600 mm area, it reportedly is possible to cut features with an aperture of ±9 µm and a positional tolerance of ±12.5 µm. Permits cutting of circular pads with a diameter of 30 to 800 µm. The LPKF MultiCut is designed for the best possible metal stencil cutting quality; permits minimum apertures of 40 µm diameter.
