Abstract: Automated systems and methods for priming a fluid chamber of a fluid dispensing valve with fluid from a fluid material source that includes a vacuum source, a valve priming station, a vacuum switch, and a controller. The valve priming station has a boot, a vacuum chamber, and a vacuum channel in the boot. The vacuum channel connects with the vacuum source via the vacuum chamber. The boot sealingly engages a valve nozzle of the fluid dispensing valve so that the vacuum chamber connects the vacuum source with the fluid chamber. The vacuum switch couples with the vacuum channel via the vacuum chamber and has an opened and closed position based upon a vacuum level in the vacuum chamber. The controller is electrically connected with the vacuum source and vacuum switch and controls priming of the fluid dispensing valve based upon whether the vacuum switch is opened or closed.

Abstract: A non-contact jetting dispenser, viscous fluid dispensing system and method. The system includes a viscous fluid dispenser for dispensing the viscous fluid. The system further includes a viscous fluid supply container adapted to hold the viscous fluid. A flow path is provided for the viscous fluid between the viscous fluid supply container and an outlet of the viscous fluid dispenser. An electronic flow meter device is used to produce electrical output signals proportional to the flow rate of the fluid flowing through the flow path. A control is operatively coupled to the electronic flow meter for continuously receiving and processing the electrical output signals and performing a responsive control function in a closed loop manner.

Abstract: A jetting device and/or fluid module include a module body defining a passageway extending through the module body and also partially defining a fluid chamber, a nozzle supported by the module body, a valve element at least partially within the fluid chamber, a biasing element contacting the valve element and also contacting the module body, and a sealing member contacting the periphery of the valve element and configured to partially define the fluid chamber. The nozzle defines a fluid outlet that is in fluid communication with the fluid chamber. The valve element has an upper portion outside of the fluid chamber that is adapted for contact with the drive pin, and the biasing element is configured to apply a spring force to the valve element. The valve element is configured to cause a droplet of the fluid to be jetted from the fluid outlet when the valve element is moved in the direction toward the nozzle.

Abstract: Methods and systems of accurately dispensing a viscous fluid onto a substrate. In an embodiment, a method includes using an electronic flow meter device to produce electrical flow meter output signals and performing a responsive control function in a closed loop manner by adjusting at least one dispensing parameter to correct for a difference between an output data set and a reference data set. In another embodiment, a system includes a control operatively coupled to a gas flow meter device and to a weigh scale allowing for a density of an amount of viscous material to be determined. In another embodiment, a method includes using a control coupled to both a gas flow meter device and a weigh scale and performing a responsive control function in a closed loop manner by adjusting at least one dispensing parameter using gas flow meter output signals and weigh scale output signals.

Abstract: Methods for applying fluid materials to a substrate, such as circuit board, while continuously moving the fluid dispenser. Some methods generally involve correcting the dispense location for each of the dispensed amounts of fluid material by executing a statistical comparison of either the predicted and actual landing locations on the substrate, or the predicted and actual positions of the dispenser at each of the dispense locations. Other methods generally involve initiating the dispensing of amounts of the fluid material at dispense locations corrected by a correction factor specified in terms of the servo cycle for the movement of the dispenser or by a correction factor specified in terms of partial servo cycles courtesy of a timer.

Abstract: Methods for applying an underfill with vacuum assistance. The method may include dispensing the underfill onto a substrate proximate to at least one exterior edge of an electronic device attached to the substrate. A space between the electronic device and the substrate is evacuated through at least one gap in the underfill. The method further includes heating the underfill to cause the underfill to flow into the space. Because a vacuum condition is supplied in the open portion of the space before flow is initiated, the incidence of underfill voiding is lowered.
