  • Method for compressing viscous material through openings
    Patent number: 6761926
    Abstract: A novel apparatus for compressing viscous material through openings in a stencil is disclosed. The novel apparatus has a compression head cap which provides a contained environment to direct and to aid the flow of pressurized viscous material through the openings in the stencil.
    Type: Grant
    Filed: September 19, 1996
    Date of Patent: July 13, 2004
    Assignee: Visteon Global Technologies, Inc.
    Inventors: Vinh Van Ha, Jeff J. Lin
  • Method and apparatus for dispensing viscous material
    Patent number: 6423141
    Abstract: A novel apparatus for compressing viscous material through openings in a stencil is disclosed. The novel apparatus has a compression head cap which provides a contained environment to direct and to aid the flow of pressurized viscous material through the openings in the stencil. The compression head cap further includes a plurality of members which are selectively and movably disposed within the contained environment and which selectively remove an amount of the material from the environment, effective to prevent the material from being undesirably dispensed by the head cap.
    Type: Grant

  • Method and apparatus for dispensing viscous material
    Patent number: 6395087
    Abstract: A novel apparatus for compressing viscous material through openings in a stencil is disclosed. The novel apparatus has a compress on head cap which provides a contained environment to direct and to aid the flow of pressurized viscous material through the openings in the stencil. In another embodiment of the invention, the compression head includes a viscous material reception chamber which has a certain shape which is effective to cause said received viscous material to be selectively dispensed while having a substantially uniform velocity profile and which further provides for the creation of a substantially uniform pressure profile.

  • METHOD AND APPARATUS FOR DISPENSING VISCOUS MATERIAL
    Publication number: 20010054627
    Abstract: A novel apparatus for compressing viscous material through openings in a stencil is disclosed. The novel apparatus has a compression head cap which provides a contained environment to direct and to aid the flow of pressurized viscous material through the openings in the stencil. The apparatus further includes a selectively expandable diaphragm which selectively and expandably allows the viscous material to be dispensed into the compression head cap.
    Type: Application

  • Method and apparatus for dispensing viscous material
    Patent number: 5824155
    Abstract: A novel apparatus for compressing viscous material through openings in a stencil is disclosed. The novel apparatus has a compression headcap which provides a contained environment to direct and to aid the flow of pressurized viscous material through the openings in the stencil. The compression headcap includes two generally parallel wiper blades that are biased into sliding communication with the stencil. Longitudinal diffuser plates guide and equalize the flow of the viscous material into the volume between two generally parallel wiper blades.
