摘要： Embodiments include measuring motion characteristics of the workpiece through the placement process. Since the component is placed on the workpiece with some force to ensure proper adhesion to the workpiece, some deflection of the workpiece is expected during the placement cycle. The placement force is adjusted to ensure that the component is safely placed into the solder paste or adhesive. Placement force is adjusted through a number of characteristics including: choice of spring tension in the nozzle; the length of the nozzle and the amount of over-travel into the board; the rigidity of the board and design; and the placement of the board support mechanisms. With proper adjustment of these characteristics and parameters, high quality placements onto the workpiece can be ensured.

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： 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 laser based, noncontacting measurement instrument is particularly adapted for the printed circuit board drilling industry to measure drill diameter, runout, and tip position under actual operating conditions. A laser beam is focused in space and the amount of light occluded by the drill bit as the bit is passed through the beam is sensed by a detector. Diameter, runout, and tip position are calculated by measuring the amount of occlusion, monitoring the position and angular orientation of the rotating drill, and correlating the amount of light occlusion to the position and angular orientation of the drill. The instrument automatically compensates for dust and debris in the optical path.

摘要： A laser based optically triggered sensor system is described which can function as a coordinate measuring machine (CMM) probe. With the sensor, a CMM can find the exact location of the surface of a test object without physically having to touch the object. The reflectivity of the laser beam is sensed by a detector pair. The ratio of light on the detector pair is sensed and used to indicate when the probe is in range for a measurement, out of range for the measurement, and when in range, whether the object being sensed is too far or too close from the trigger point of the probe. The system is a plug compatible replacement for existing contact trigger probes currently used on most CMM's.

摘要： A laser endoscope includes a micro-thin optic cable assembly which may be inserted into a body cavity by micro-surgical or non-surgical procedures. A coherent jacketed fiber optical bundle is provided in the center of the assembly having a diameter of no more than 3.5 mm. with an optical lens system at the distal end for reflecting an image of a portion of the interior of the cavity. A pair of single optical fibers are spirally wound around the cable, each of which has a total diameter including a jacket of approximately 140 microns. One of these fibers carries a laser light beam to the cavity and the other is for redundancy.The proximate end of the optical cable assembly connects to a remote unit wherein a laser diode light source is provided to direct a beam of light into the end of one of the single optical fibers. A TV camera is also provided in the remote unit together with suitable optics for transmitting the image from the optical cable to a viewing screen on the remote unit.
