    摘要： 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.

    摘要： 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.

    摘要： Methods for applying an underfill with vacuum assistance. The method includes receiving a substrate with the surface at least partially covered by a glass-like film that has a top surface of reduced roughness relative to the surface of the substrate, providing the underfill on the top surface of the glass-like film along an exterior edge of the electronic device, evacuating the space to provide a vacuum condition in the open portion of the space, and heating the underfill to cause flow of the underfill toward the exterior edge and into the open portion of the space, wherein the glass-like film reduces trapping of gas under the underfill.

    摘要： 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.

    摘要： Methods for applying fluid materials to a substrate, such as circuit board, while continuously moving the fluid dispenser are disclosed. Initially, a dispenser is continuously moved through a constant motion trajectory connecting the plurality of dispense locations on the substrate. The electrical output signals generated by one or more of encoders of the dispenser are monitored as the dispenser is continuously moved through the constant motion trajectory. The dispenser is triggered at each of the plurality of dispense locations and droplets of the fluid material are jetted while continuously moving the dispenser. The spatial coordinates of each droplet of the fluid material on the substrate are measured and compared to expected landing coordinates for each droplet of the fluid material to generate a spatial error for each droplet of the fluid material. At least one dispense location is corrected and an updated constant motion trajectory is generated.
