Patent ID: 6955946

Claim:
A method of dispensing a viscous material on an electronic component with a dispensing system including a dispensing element, the method comprising: pressurizing a reservoir for holding the viscous material; metering a variable amount of the viscous material from the pressurized reservoir using a positive displacement pump coupled with the dispensing element and positioned outside the pressurized reservoir; dispensing a test amount of the viscous material from the dispensing element onto a calibrating device using the positive displacement pump; measuring the test amount with the calibrating device; producing at least one signal representative of the measured test amount; selecting the speed of movement of a positioner for moving the dispensing element relative to the electronic component based on the at least one signal to cause the dispensing element to dispense a desired amount of the viscous material; and dispensing the viscous material on the electronic component with the dispensing element using the positive displacement pump.
