Patent number: 8257779Abstract: A viscous material noncontact jetting system has a jetting dispenser mounted for relative motion with respect to a surface. A control is operable to cause the jetting dispenser to jet a viscous material droplet that is applied to the surface as a viscous material dot. A device, such as a camera or weigh scale, is connected to the control and provides a feedback signal representing a size-related physical characteristic of the dot applied to the surface. The size-related physical characteristics of subsequently applied dots is controlled by heating and cooling, or adjusting a piston stroke in the jetting dispenser, in response to the size-related physical characteristic feedback. Dispensed material volume control and velocity offset compensation are also provided.Type: GrantFiled: April 4, 2011Date of Patent: September 4, 2012Assignee: Nordson CorporationInventors: Ron Abernathy, Alec J.

Publication number: 20120205392Abstract: Apparatus and methods for dispensing small amounts of a viscous material onto a workpiece. The narrow-profile dispensing apparatus includes a fluid chamber, a nozzle, and a valve seat disk representing individual components that are removable from a main body of the dispensing apparatus for cleaning and/or replacement. The nozzle is coupled with the fluid chamber by a heat transfer body that may be cooled by, for example, a cooling fluid routed through an air pathway defined in the heat transfer body. The main body of the dispensing apparatus may be cooled by air exhausted from an air cavity of a pneumatic actuator regulating the movement of a needle to control the flow of viscous material in the dispensing apparatus.Type: ApplicationFiled: April 24, 2012Publication date: August 16, 2012Applicant: NORDSON CORPORATIONInventors: Erik Fiske, Horatio Quinones, Phil Maiorca, Alec Babiarz, Robert Ciardella

Publication number: 20050082670Abstract: Apparatus and methods for preapplying discrete amounts of underfill material of a component on a component substrate before the solder bumps of the component are joined by reflow with a packaging substrate to create a microelectronics package. The underfill material is preferably applied by a noncontact dispensing technique as discrete amounts at interstitial areas on an active surface of the component substrate defined between nearest-neighbor solder bumps. The underfill material forms a continuous meniscus of underfill material across the interstitial areas not occupied by the solder bumps and forms a collar encircling each of the solder bumps. The cured underfill material strengthens and improves the reliability of the solder joints formed by the bump reflow.Type: ApplicationFiled: September 9, 2004Publication date: April 21, 2005Inventors: Horatio Quinones, Liang Fang, Dave Ellis, Erik Fiske, Thomas Ratledge, Alec Babiarz, Robert Ciardella

Publication number: 20040214370Abstract: Methods for underfilling a gap between a component and a component carrier, such as a die joined to a substrate by solder electrical interconnections, with an underfill material. One or more chambers or passageways are provided in either the component carrier at a location beneath the intended position of the component or in the component itself. The component and component carrier are heated and a volume of underfill material is introduced into each passageway. After introduction, the underfill material flows or moves to fill the gap between the component and the component carrier. A fillet may be optionally formed by adjusting the temperature during the underfilling operation.Type: ApplicationFiled: January 27, 2004Publication date: October 28, 2004Applicant: Nordson CorporationInventors: Horatio Quinones, Erik Fiske, Thomas Laferl Ratledge, Alec J.
