摘要

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.
