摘要： Methods and arrangements are provided to efficiently use 3-D vision systems to measure selected features of objects that are semi-constrained in compartmented trays having a uniform geometric arrangement. The methods are particularly well suited for optimizing the 3-D measurement of leads on integrated circuit devices which are packaged in trays.

摘要： A method and apparatus is provided for calibrating distance measuring instruments, in particular, optical three dimensional measurement sensors. The method is not restricted to aligning the motion of the calibrating surface to be parallel to the sensor centerline. Accordingly more than one sensor can be present during the calibration procedure. This leads to the practicality of aligning multiple sensor systems using a common translation stage for all sensors or using translation stages that are a part of the system. The joint calibration of sensors embedded in a system guarantees proper registration without additional steps. A method for calibrating optical sensors to accuracies approaching the wavelength of light is given.

摘要： A system and method of determining a height and/or position of at least one element on an area array device. A laser beam scans the area array device using at least two different laser light intensities. Reflected light is sampled, and the height and/or position of the element is determined using, e.g., optical triangulation.

摘要： Methods and arrangements are provided to efficiently use 3-D vision systems to measure selected features of objects that are semi-constrained in compartmented trays having a uniform geometric arrangement. The methods are particularly well suited for optimizing the 3-D measurement of leads on integrated circuit devices which are packaged in trays. For obtaining the three-dimensional data, a multi-pocketed tray is provided with tray pockets arranged in rows and columns. Corresponding sides of the multiple parts or devices in a row or column are scanned sequentially with at least one three-dimensional sensor. This scanning procedure is repeated for all rows and columns containing sides of the devices from which data is to be obtained. The devices can be first aligned by applying directional vibration to the tray to drive all the parts or devices to the same corner or side of the respective pockets.
