    Abstract: An apparatus to dispense a droplet of liquid, such as solder flux, onto the surface of a substrate, such as a printed circuit board, and thereafter flatten the droplet with a burst of pressurized air directed onto the droplet. A dispenser has a dispenser body (12), which has a liquid supply passageway (56) adapted to connect to a source of liquid. A nozzle body(14) connects to the dispenser body (12) and includes a liquid discharge passageway (58a) in fluid communication with the liquid supply passageway (56). The nozzle body (14) also has an air discharge orifice (72) which is adapted to connect to a source of pressurized air for selectively discharging bursts of pressurized air. The air discharge orifice (72) is configured and aligned with the liquid discharge passageway (58a) so that the discharged bursts of pressurized air impinge upon one of the droplets of liquid dispensed from the liquid discharge passageway (58a) so as to flatten that droplet and thereby increase the contact area between the droplet and the substrate.

    Abstract: Apparatus and methods for dispensing droplets of liquid or viscous material are disclosed. A valve is opened to dispense a stream of the heated liquid or viscous material through an elongated orifice of a nozzle. The stream of material being dispensed from the elongated orifice is broken into droplets by rapidly closing the valve. The apparatus includes a seat assembly wherein the valve has three positions with respect to the valve seat and may have a nozzle assembly wherein the nozzle is constructed of a thin walled tube. Furthermore, a method for varying the height of a droplet of liquid or viscous material is disclosed by which two or more droplets combine to form a droplet of a desired height. A method for applying a plurality of droplets of material onto a substrate so that the droplets flow together to form a uniform film of desired thickness and shape is also disclosed. A second embodiment of the invention relates to dispensing apparatus with a heater assembly removably attached to the dispenser housing.

    Abstract: A method and apparatus for forming and dispensing a coating material formulation containing a liquid coating composition and a supercritical fluid as a diluent comprises a closed vessel having a hollow interior; a system for supplying fluid diluent into the vessel interior and for transforming the fluid diluent into supercritical fluid within the vessel; and, a system for introducing liquid coating composition into the vessel interior in such a way, that it is sufficiently exposed to the supercritical fluid to form a fluid diluent rich phase and a liquid coating composition or resin rich phase which is saturated with supercritical fluid up to or near its saturation point for the temperature and pressure conditions within the vessel. The resin rich phase has a higher density than the fluid diluent rich phase and therefore collects on the bottom of the vessel from where it is withdrawn and supplied to coating dispensers for deposition on a substrate. The coating material formulation which is not discharged from the dispensers is preferably recirculated back into the closed vessel in such a way that it is permitted to absorb sufficient supercritical fluid to return to the saturation point.

    Abstract: A method and apparatus for dispensing a foamable, pressurized solution of a gas and a high viscosity polymeric material in a manner which pro­duces a foamed bead (100) having a hollow core. Initial foaming (57) occurs in a nozzle (12) through which the solution is dispensed to atmosphere, at the core of the bead. Subsequent foaming of of the bead exteriorly of the core occurs outside the nozzle, and results in an extruded, foamed bead (60) of high viscosity polymeric material having a tubular shape and particularly suitable for form-in-place gasket applications.
