Abstract: A method of dispensing material includes delivering an electronic substrate to a dispense position. The electronic substrate has at least two identical patterns and at least two fiducial marks. The method further includes capturing at least one image of the at least two fiducial marks provided on the electronic substrate, analyzing the at least one image to determine a position of the electronic substrate in X axis, Y axis and theta directions, calculating a rotational angle of the electronic substrate, and rotating a dispensing pump array to match an angle of the electronic substrate. Alternatively, the electronic substrate can be rotated to match an angle of the dispensing pump array.

Abstract: A conveyor system for a stencil printer includes a pair of rail members extending through a frame and configured to transport the substrate through the stencil printer. A lift tool assembly is configured to support the substrate at a transport height and a print height. The lift tool assembly includes a lifter portion configured to be engaged by a support of the lift table assembly. A foot of the lifter portion has at least two permanent magnets configured to secure the foot of the lifter portion to the support when engaging the support to the lifter portion, and at least one vacuum pocket formed in a bottom surface of the foot of the lifter portion. The vacuum pocket is configured to selectively secure the lifter portion in place on the support.

Abstract: A method is used to identify and compensate for errors created by changes in the relative positions of a deposition unit and a vision system of a dispenser. The method includes calibrating the vision system, dispensing a pattern of features over a working area, moving the vision system over a deposition location to locate a deposition, obtaining an image of the deposition, tagging data associated with the image, calculating a relative distance between the deposition unit and the vision system, storing correction data with spatial location in a file for later use, and using the stored data to make small corrections prior to dispensing additional material.
