Abstract
A fluidic dispensing device includes a first fluid supply containing a primary fluid and a second fluid supply containing a humidification fluid. A plurality of primary nozzles in fluid communication with the first fluid supply eject the primary fluid and a plurality of humidification nozzles in fluid communication with the second fluid supply eject the humidification fluid for controlling a humidity of an environment adjacent the plurality of primary nozzles.
Claims18
A fluidic dispensing device comprising:
- a first fluid supply containing a primary fluid;
- a second fluid supply containing a humidification fluid;
- a plurality of primary nozzles in fluid communication with the first fluid supply for ejecting the primary fluid onto a target substrate;
- a plurality of humidification nozzles in fluid communication with the second fluid supply for ejecting the humidification fluid and controlling a humidity of an environment adjacent the plurality of primary nozzles;
- and
- a humidification substrate positioned between the plurality of humidification nozzles and the target substrate for absorbing the humidification fluid ejected from the plurality of humidification nozzles while allowing the primary fluid to be ejected from the plurality of primary nozzles onto the target substrate.
