Abstract
Methods for applying fluid materials to a substrate, such as circuit board, while continuously moving the fluid dispenser. Some methods generally involve correcting the dispense location for each of the dispensed amounts of fluid material by executing a statistical comparison of either the predicted and actual landing locations on the substrate, or the predicted and actual positions of the dispenser at each of the dispense locations. Other methods generally involve initiating the dispensing of amounts of the fluid material at dispense locations corrected by a correction factor specified in terms of the servo cycle for the movement of the dispenser or by a correction factor specified in terms of partial servo cycles courtesy of a timer.
