Abstract:
A method of calibrating a dispensing system that dispenses material onto a substrate according to a predetermined pattern, the dispensing system having a dispensing pump that dispenses material and a gantry system that controls movement of the pump over the substrate and over a calibration system, the method comprising steps of:(a) moving the pump over the calibration system; (b) dispensing a quantity of material from the pump while the pump is moved by the gantry system according to a calibration pattern that is representative of the predetermined pattern; (c) determining the quantity of material dispensed; (d) comparing the quantity of material dispensed with a target quantity; and (e) adjusting characteristics of the dispensing system when a difference between the quantity of material dispensed and the target quantity is greater than a predetermined tolerance.
