Abstract: A calibration and part inspection method for the inspection of ball grid array, BGA, devices. Two cameras image a precision pattern mask with dot patterns deposited on a transparent reticle. The precision pattern mask is used for calibration of the system. A light source and overhead light reflective diffuser provide illumination. A first camera images the reticle precision pattern mask from directly below. An additional mirror or prism located below the bottom plane of the reticle reflects the reticle pattern mask from a side view, through prisms or reflective surfaces, into a second camera and a second additional mirror or prism located below the bottom plane of the reticle reflects the opposite side view of the reticle pattern mask through prisms or mirrors into a second camera. By imaging more than one dot pattern the missing state values of the system can be resolved using a trigonometric solution. The reticle with the pattern mask is removed after calibration and the BGA to be inspected is placed with the balls facing downward, in such a manner as to be imaged by the two cameras. The scene of the part can thus be triangulated and the dimensions of the BGA are determined.

Abstract: An apparatus for three dimensional inspection of an electronic part which has a camera and illuminator for imaging a first view of the electronic part. An optical element is positioned to reflect a different view of the electronic part into the camera, and the camera thus provides an image of the electronic part having differing views of the electronic part. An image processor applies calculations on the differing views to calculate a three dimensional position of at least one portion of the electronic part.

Abstract: An articulated work machine is steered via left and right hydraulic cylinders that swivel a front portion of a work machine relative to a back portion about a vertical articulation axis. When a low force turn is being performed, high pressure is supplied to only one of the left and right hydraulic cylinders. When a high force turn is performed, high pressure is supplied to one of the left and right hydraulic cylinders, and pressurized hydraulic fluid is also supplied to the other of the left and right hydraulic cylinders in proportion to the torque required for the turn. This strategy allows for excess pressurized fluid, which is not used for the steering purpose, to be utilized by hydraulic implements of the work machine to increase performance capabilities while the machine is being steered in low force mode under light steering load.
