摘要： 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.

摘要： A novel inspection system for inspecting an article of manufacture, such as a printed circuit board, is disclosed, where the system includes a strobed illuminator adapted to project light through a reticle so as to project a pattern of light onto an area of the printed circuit board. A board transport responsively positions the board to at least two distinct positions, where each position corresponding to a different phase of the projected light. Also included is a detector adapted to acquire at least two images of the area, each image corresponding to one of the at least two different phases. An encoder monitors the movement of the board and outputs a position output, and a processor connected to the encoder, the board transport, the illuminator and the detector controlledly energizes the illuminator to expose the area as a function of the position output, the processor co-siting the at least two images and constructing a height map image with the co-sited images.

摘要： A method of calibrating a pick and place machine having an on-head linescan sensor is disclosed. The calibration includes obtaining z-axis height information of one or more nozzle tips via focus metric methods, including a Fourier transform method and a normalized correlation method. Additionally, other physical characteristics such as linear detector tilt, horizontal scale factor, and vertical scale factor are measured and compensated for in the process of placing the component. Nozzle runout, another physical characteristic, is also measured by a sinusoidal curve fit method, and the resulting Z-height calibration data is used to later place the component.
