ABSTRACT:
A paste dispensing system for dispensing paste to a substrate such as a ceramic greensheet or other electronic component substrate comprises a reservoir for holding the paste and a nozzle housing in fluid communication with the reservoir and having an opening therein through which the paste is dispensed. The nozzle housing has disposed therein a rotatable slotted shutter which is in fluid communication with the reservoir and which has an auger disposed in the shutter. The auger when actuated, draws paste from the reservoir into the shutter, advances the liquid material through the shutter and circulates the paste back to the reservoir. When it is desired to dispense the paste, the shutter is rotated so that the slot in the shutter communicates with a slot in a nozzle plate connected to the nozzle housing through which slot the paste is dispensed. The paste is continually circulated through the paste dispensing system by the auger whether or not paste is being dispensed. A paste cartridge is also provided for use with the paste dispensing system and is easily attached or removed from the system reservoir avoiding downtime in the paste dispensing operation. A method is also provided for applying a layer of paste to a substrate using the paste dispensing system of the invention.
