International Classification:

H05K 3/00

US Classification:

427 984, 118323

Abstract:

A material deposition system includes a frame, a support coupled to the frame to support an electronic substrate during a deposit operation, a gantry coupled to the frame, and a deposition head coupled to the gantry. The deposition head is movable over the support by movement of the gantry. The deposition head includes a chamber to hold material, an actuator to push a volume of material out of the chamber, a needle extending from the chamber and terminating in a needle orifice, and at least two air jets located on opposite sides of the needle orifice. A desired volume of material is formed at the needle orifice in response to the actuator, and each of the at least two air jets produce a timed pulse of air to create a micro-droplet from the desired volume and to accelerate the micro-droplet to high velocity.

International Classification:

B08B 9/032

US Classification:

134 2212

Abstract:

A method for cleaning a nozzle of a material deposition system configured to deposit material on an electronic substrate includes: performing a deposition operation with a material deposition system configured to position an electronic substrate under a deposition head movable by a gantry, to supply material to a chamber of the deposition head, to extend a piston of the deposition head from the chamber, the needle terminating in a needle orifice, and to push a volume of material out of the chamber by an actuator of the deposition head to form a desired volume of material at the needle orifice that is deposited on the electronic substrate; and cleaning the needle orifice with air directed to the needle orifice.
