    Abstract: A method of calibrating a dispenser of the type having a material dispensing unit that is configured to dispense material on a substrate includes providing a weigh scale having a plate configured to receive material dispensed on the plate, dispensing one or more patterns of material on the plate; weighing the amount of material dispensed on the plate, and comparing the weighed amount of material to a designated amount of material. The act of dispensing one or more patterns of material replicates at least a portion of patterns of material dispensed on the substrate during a dispensing operation. A controller for performing the method is further disclosed.

    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.

    Abstract: A dispensing system for depositing material on an electronic substrate includes a frame, a dispensing unit gantry movably coupled to the frame, a dispensing unit coupled to the dispensing unit gantry, a vision system gantry coupled to the frame, and a vision system coupled to the vision system gantry. A controller is configured to manipulate the vision system with the vision gantry system to move to the position defined by a feature, to acquire an image of at least a portion of a feature, to search for an edge of interest along a center of the image, and to return a value indicating an offset of zero (0), which is interpreted as the location that is exactly as expected, and an offset that reflects where the edge of interest intersected that axis location.
