An automated system includes improved height sensing. In one aspect, a on-head camera performs the dual functions of fiducial imaging and height sensing using an auxiliary off-axis light source and triangulation. In another aspect, an on-head height sensor is positioned to measure height at a location that is not beneath any nozzles. The sensor provides height information at a plurality of locations over the board, and a height map of the board is created. In yet another aspect of the invention, the above features are combined to provide an on-head camera that images fiducials and measures height at a plurality of locations such that a height map is created.

Improved component placement inspection and verification is performed by a pick and place machine. Improvements include stereovision imaging of the intended placement location; enhanced illumination to facilitate the provision of relatively high-power illumination in the restricted space near the placement nozzle(s); optics to allow image acquisition device to view the placement location from an angle relative to a plane of the placement location, thereby reducing the possibility of such images being obstructed by the component; techniques for rapidly acquiring images with commercially available CCD arrays such that acquisition of before and after images does not substantially impact system throughput; and image processing techniques to provide component inspection and verification information.

An optical inspection system and method are provided. A workpiece transport moves a workpiece in a nonstop manner. An illuminator includes a light pipe and is configured to provide a first and second strobed illumination field types. First and second arrays of cameras are arranged to provide stereoscopic imaging of the workpiece. The first array of cameras is configured to generate a first plurality of images of the workpiece with the first illumination field and a second plurality of images of the feature with the second illumination field. The second array of cameras is configured to generate a third plurality of images of the workpiece with the first illumination field and a fourth plurality of images of the feature with the second illumination field. A processing device stores at least some of the first, second, third, and fourth pluralities of images and provides the images to an other device.

Embodiments of the present invention improve upon component level inspection performed by pick and place machines. Such improvements include providing first article inspection in pick and place machines by collecting images of the placement event inside the machine and identifying errors as they happen. By displaying this information as it is generated on the machine, the operator can take prompt and effective corrective actions. In one embodiment, images are taken of the placement location before and after placement of the component. These images are then processed and displayed to the operator shortly after the placement has completed. In addition to the images, key measurements are displayed to the operator to assist in the diagnosis of problems as they occur. Key features that are presented to the operator include absence/presence detection, vibration detection and manual visual inspection.
