    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 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.

    摘要: 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.

    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.
