Abstract:
A liquid deposition system comprises a liquid delivery assembly including a dispensing probe having a sidewall including a first end having a liquid port and a second end having a tip, and a flow path opening at the tip and fluidly connected with the liquid port. The system includes a gas injection assembly with a manifold having a gas nozzle, a nozzle opening, and a gas port, the gas nozzle configured to eject a substantially laminar gas stream so that the gas stream travels through a travel path, the tip of the dispensing probe extending into the travel path. The liquid port is fluidly connectable with a liquid source and the gas port is fluidly connectable with a pressurized gas source, so that a liquid micro droplet is formed at the tip. The laminar gas stream separates the micro droplet from the tip and carries it through the travel path.
