Abstract
A digital dispense device and method for ejecting one or more fluids into a target area of a substrate. The digital dispense device includes (A) a fluid ejection head for the digital dispense device having one or more arrays of fluid ejectors thereon; (B) a fluid ejection head translation device for moving the ejection head over the target area of the substrate in a first direction, wherein the one or more arrays of fluid ejectors on the fluid ejection head are oriented parallel to the first direction; and (C) a control device for activating one or more fluid ejectors in the one or more arrays of fluid ejectors as the one or more fluid ejectors intersect the target area of the substrate.
Claims20
A digital dispense device for ejecting one or more fluids into a target area of a substrate, the digital dispense device comprising;
- :
- A) a fluid ejection head for the digital dispense device having a comprising four linear array arrays of fluid ejectors thereon, wherein each linear array of fluid ejectors comprises two columns of fluid ejection nozzles disposed on opposing sides of a fluid supply via, and wherein the fluid ejectors are grouped by primitives from a first end of the each linear array to a second end of the said linear array;
- B) a fluid ejection head translation device for moving the ejection head over the target area of the substrate in a first direction, wherein the each linear array of fluid ejectors on the fluid ejection head are oriented parallel to the first direction;
- and
- C) a control device for sequentially activating all of the primitives of fluid ejectors in the each linear array of fluid ejectors as the linear array of fluid ejectors intersects the target area of the substrate.
A method for dispensing a predetermined amount of fluid into a target area of a substrate, comprising:
- providing a digital dispense device, the digital dispense device comprising;
- :
- A) a fluid ejection head for the digital dispense device having a comprising four linear array arrays of fluid ejectors thereon, wherein each linear array of fluid ejectors comprises two columns of fluid ejection nozzles disposed on opposing sides of a fluid supply via, and wherein the fluid ejectors are grouped by primitives from a first end of the each linear array to a second end of the said linear array;
- B) a fluid ejection head translation device for moving the ejection head over the target area of the substrate in a first direction, wherein the each linear array of fluid ejectors on the fluid ejection head are oriented parallel to the first direction;
- and
- C) a control device for sequentially activating all of the primitives of fluid ejectors in the each linear array of fluid ejectors as the linear array of fluid ejectors intersects the target area of the substrate;
- moving the fluid ejection head over the target area of the substrate while activating one or more primitives of fluid ejectors to eject fluid into the target area until a predetermined amount of fluid is deposited in the target area.
A fluid ejection head for a digital dispense device, the fluid ejection head comprising a four linear array arrays of fluid ejectors thereon, wherein each linear array of fluid ejectors comprises two columns of fluid ejection nozzles disposed on opposing sides of a fluid supply via, and wherein the fluid ejectors are grouped by primitives from a first end of the each linear array to a second end of the said linear array and wherein the each linear array of fluid ejectors on the fluid ejection head is oriented parallel to a direction of travel of the fluid ejection head in the digital dispense device, for sequential activation of the primitives of fluid ejectors over a target area.
