Microstructure of a fractured MLCC die, Take #2

3D Model

This is a science/tech photo-based model showing what’s inside a multi-layer ceramic capacitor (MLCC). I physically broke open an MLCC so as to expose the alternating layers of metal conductor and ceramic insulation. Then I photographed the broken surface using a 20X NA 0.75 microscope objective and focus stacking, recovered the 3D structure using the “depth map” feature of Zerene Stacker, and used Blender to make this model. The near-vertical “cliffs” are actually overhangs that are not captured properly by any depth map. The smooth “talus slopes” below the cliffs are also unrealistic artifacts of the depth map process. The area covered is about 0.15 mm by 0.24 mm in real life. See https://www.photomacrography.net/forum/viewtopic.php?f=27&t=47136 for more discussion. Unlike Take #1, I believe that this model is geometrically correct to within measurement error.
