    Abstract: A device configured to jet one or more droplets of a viscous medium includes a housing at least partially defining a jetting chamber, a supply conduit that supplies the viscous medium into the jetting chamber, a jetting nozzle, an impacting device configured to force the one or more droplets of the viscous medium through the conduit of the jetting nozzle to be jetted as the one or more droplets, and a supply conduit actuator configured to adjust a hydrodynamic resistance of at least a portion of the supply conduit to viscous medium flow from the jetting chamber via the supply conduit, based on moving through the portion of the supply conduit, independently of the impacting device, to adjust a cross-sectional flow area of the portion of the supply conduit.

    Abstract: A method for mounting a component (100) on a workpiece (106), the method comprising obtaining information regarding a surface topography of at least one of a mounting surface (102) of the component and a local surface (108) of the workpiece onto which the component is to be mounted. The method further comprises forming a plurality of deposits (110) of a viscous medium on at least one of the mounting and local surfaces, wherein each of the plurality of deposits has a height (/½, /½, h3) based on the obtained information, and is formed by individually applying at least one droplet (234) of the viscous medium (232) using non-contact dispensing. The method further comprises placing the component on the substrate, such that the plurality of deposits of viscous medium forms a connection between the component and the workpiece.

    Abstract: A device configured to jet one or more droplets of a viscous medium may include a housing having an inner surface at least partially defining a jetting chamber configured to hold the viscous medium, and a flexible jetting nozzle. The flexible jetting nozzle may include a flexible conduit extending between an inlet orifice in an inner surface to an outlet orifice in an outer surface. The device may cause an increase of internal pressure of viscous medium in the jetting chamber to force one or more droplets of viscous medium through the flexible conduit and through the outlet orifice. The flexible jetting nozzle may include a flexible material. The flexible jetting nozzle may deform, to cause a cross-sectional area of the flexible conduit to dilate, in response to the increase of the internal pressure of the viscous medium in the jetting chamber.

    Abstract: A jetting device configured to jet one or more droplets of a viscous medium through a nozzle may include an acoustic transducer configured to emit an acoustic signal that transfers acoustic waves into at least a portion of the viscous medium located in a viscous medium conduit a viscous medium conduit configured to direct a flow of the viscous medium to an outlet of the nozzle. The acoustic signal may be an ultrasonic signal. The acoustic signal may adjust one or more rheological properties of the viscous medium, based on acoustic actuation. The acoustic transducer may be implemented by an actuator of the device that is configured to move through an eject chamber to cause viscous medium to be jetted through the outlet of the nozzle as one or more droplets.

    Abstract: A jetting device configured to jet one or more droplets of a viscous medium through the outlet of a nozzle includes an energy output device. The energy output device is configured to direct a quantum of energy into at least a portion of the volume of the viscous medium jetted through the outlet to control a breaking of the droplet from the nozzle. The energy output device may include an acoustic transducer or a piezoelectric material or a laser emitter or a heater.
