Abstract:
1. A method for depositing material on an electronic substrate, the method comprising: positioning an electronic substrate under a deposition head movable by a gantry; supplying material to a chamber of the deposition head; extending a needle of the deposition head from the chamber, the needle terminating in a needle orifice; pushing a volume of material out of the chamber with an actuator of the deposition head to form a desired volume of material at the needle orifice; locating at least two air jets on opposite sides of the needle orifice; and producing a timed pulse of air to create a micro-droplet from the desired volume and to accelerate the micro-droplet to high velocity to deposit the micro droplet, the timed pulse of air being directed perpendicular to a direction of the micro-droplet.
