    摘要： The present invention includes a method of determining a location of a component on a workpiece. A before-placement standard image is acquired of an intended placement location on a standard workpiece. Then, a standard component is placed upon the standard workpiece and the placement is verified. An after-placement standard image is acquired and a standard difference image is created from the before and after standard images. Then, a before-placement test image is acquired of an intended placement location on the workpiece. A component is then placed upon the workpiece, and after-placement test image is acquired. A test difference image is created from the before and after test images. A first offset is calculated between the before standard difference image and the before test image. Then, the test difference is transformed based on the first offset to generate a difference test image (DTR) that is registered to the standard difference image. The standard difference image is correlated to the registered difference test image (DTR) to generate a registration offset indicative of placement efficacy.

    摘要： A sensor for sensing placement information of a component to be placed by a pick and place machine is disclosed. The sensor includes a plurality of light sources each of which is disposed to direct illumination at different angles of incidence upon the component. Each source is further adapted to generate light based upon an energization signal. Source control electronics are provided and coupled to the plurality of light sources to successively and/or provide energization signals to each source. A detector is disposed within the sensor relative to the plurality of sources to receive at least one shadow of the component, and provide data at a detector output indicative of the shadow imaged while the component is rotated.

    摘要： An inspection system for inspecting web printed electronic circuitry includes a strobed illuminator, a detector, a motion encoder, and a processor. The strobed illuminator is adapted to project light through a reticle to project a pattern of light onto an area of the web. The projected light occurs in a pulse sufficiently short to essentially freeze the web motion. The system projects the pattern of light onto the area of the web in at least two different positions of the web each position corresponding to a different phase of the projected light. A detector is adapted to acquire at least two images of the area, each image corresponding to one of the at least two different phases. The motion encoder provides a position output relative to a position of the web. The processor is coupled to the encoder, the illuminator and the detector. The processor is adapted to synchronize the illuminator with the web motion to expose the area of the web. The processor co-sites the at least two images and can construct a height map image with the co-sited images.

    摘要： A method and apparatus reduces two types of undesirable glints in an optical position alignment sensor designed to orient at least two components. In one aspect, a method includes using an aperture and a positive optic to block large angle glint generated by the components. In another aspect, a detector is positioned behind the image plane of the components to reduce the effect of small angle glint.
