Abstract
A micro-fluid jetting device and a method of ejecting fluid mixtures onto a substrate. The micro-fluid jetting device includes a housing containing a logic circuit and fluid reservoirs for at least two different fluids. A micro-fluid ejection head is attached to a first end of the housing. The ejection head is in electrical communication with the logic circuit and the fluid reservoirs. At least two channel members are provided for directing fluid from the reservoirs to a plurality of fluid ejection nozzles in a nozzle plate member. The ejection nozzles for each of the at least two different fluids are arranged in the nozzle plate member so that adjacent ejection nozzles are in flow communication with different fluids. A power source in electrical connection with the micro-fluid ejection head is provided in the housing for activating the micro-fluid ejection head for jetting the fluids therefrom.
