Abstract:
1. A material applicator comprising: a frame: a substrate support coupled to the frame, the substrate support configured to support an electronic substrate; a material application device coupled to the frame, the material application device being configured to deposit assembly material onto the electronic substrate; an imaging system configured to capture three-dimensional image data of the electronic substrate, the imaging system comprising a controller coupled to at least the imaging system, the controller configured to control movement of the imaging system and configured to communicate with the image sensor assembly to produce a three-dimensional image of the topology of the electronic substrate, wherein the imagining system is configured to capture three-dimensional image data of solder paste deposited on the electronic substrate within the viewing plane, wherein the three-dimensional image data includes a specific hue that incident upon surfaces and features along the viewing plane, wherein the specific hue corresponds to an elevation, wherein the one or more illumination assembly projects one or more linear patterns, wherein the one or more linear patterns are projected at opposing angles to strengthen measurable light where the linear patterns intersect along the viewing plane to reduce shadowing effects on the electronic substrate due to adjacent topologies, and wherein the one or more linear patterns are aligned such that similar colors overlap over a range of elevations along the viewing plane.
