Abstract:
A dispenser, which is capable of dispensing viscous material on a substrate having a top surface and a bottom surface, includes a frame, a gantry system, and a dispensing unit. The gantry system is configured to move the dispensing unit in x-axis, y-axis, and z-axis directions. The dispenser further includes a substrate support assembly configured to support the substrate in a dispense position to dispense material on the top surface of the substrate and on the bottom surface of the substrate. The substrate support assembly includes a clamping system and an inverter system. The inverter system is configured to rotate the clamping system about an axis that is parallel to the y-axis direction between a first position in which the top surface of the substrate is in the dispense position and a second position in which the bottom surface of the substrate is in the dispense position.
Abstract:
A dispenser, configured to dispense material on a substrate, includes a dispensing unit having a housing with a chamber, a piston disposed in the chamber and axially movable within the chamber, and a nozzle coupled to the housing. The nozzle has an orifice co-axial with the chamber of the housing. The dispenser further includes an actuator coupled to the dispensing unit and configured to drive the up- and down movement of the piston, and a compliant assembly coupled to the actuator and the piston. The compliant assembly is configured to permit limited relative travel between the actuator and the piston. A method of dispensing is further disclosed.
Abstract:
A stencil printer for printing viscous material on an electronic substrate includes a stencil having apertures formed therein, and a print head positioned over the stencil and configured to deposit viscous material within the apertures of the stencil. The print head includes a housing defining an elongate chamber, a source port defining a passage having an inlet positioned to allow viscous material to flow into the elongate chamber, a pair of blades defining a slot that provides an outlet from which viscous material can flow out of the elongate chamber, an elongate plunger movable in the elongate chamber to reduce a volume of viscous material within the elongate chamber, and at least one sensor to detect pressure of the viscous material within the elongate chamber.

Abstract:
A combination stencil printer and dispenser includes a frame, a stencil coupled to the frame, a substrate support coupled to the frame to support a substrate in a print position, and a print head coupled to the frame to deposit and print viscous material over the stencil. In one embodiment, the combination stencil printer and dispenser further includes a cleaning assembly coupled to the frame to wipe excess viscous material from a bottom surface of the stencil. The combination stencil printer and dispenser further includes a dispenser mounted on the cleaning assembly to dispense viscous material on the substrate when the substrate is in the print position. In other embodiments, the dispenser can be mounted on a movable stencil or on an independent gantry provided within the combination stencil printer and dispenser.

Abstract:
A dispenser includes a frame, a gantry system, a dispensing unit, a substrate support assembly, a transport system, and an inverter system coupled to the frame and in communication with the transport system. The inverter system is positioned outside the substrate support assembly and configured to rotate a substrate orientation between a first position in which a top surface of the substrate is in a dispense position and a second position in which a bottom surface of the substrate is in a dispense position. The inverter system includes a first driven assembly configured to engage one edge of the substrate and a second driven assembly configured to engage an opposite edge of the substrate. The first driven assembly and the second driven assembly are configured to drive a linear movement of the substrate.
