REMOTE BULK FEED SYSTEM FOR A DISPENSING SYSTEM AND METHOD OF SUPPLYING VISCOUS MATERIAL TO A DISPENSING SYSTEM

摘要

A dispenser includes a frame, a substrate support assembly, and a gantry system to move a dispensing pump in x-axis, y-axis, and z-axis directions. The dispensing pump includes a local supply reservoir, a dispensing nozzle, a first line to provide fluid communication between the local supply reservoir and the dispensing nozzle. The dispenser further includes a remote bulk feed system coupled to the local supply reservoir of the dispensing pump. The bulk feed system includes a first remote supply container configured to contain viscous material, a second line to provide fluid communication between the remote bulk feed system and the local supply reservoir, and a first valve disposed in the second line and operable to deliver viscous material to and to cut off viscous material from the remote supply container.
