  • Pressure control system for printing a viscous material
    Patent number: 6955120
    Abstract: A printer includes a print head for dispensing viscous material, such as solder paste. The print head defines a chamber and includes at least one source port and a dispensing slot. Within the chamber, a flexible membrane segregates the chamber into a dispensing region and an activation region. Viscous material flows from a supply mounted to the source port, into the dispensing region and out the slot. A displacement mechanism is positioned to displace the flexible membrane to reduce the volume of dispensing region and to thereby dispense viscous material through the slot. The print head also includes a removable envelope through which the viscous material flows and contacts as it passes through the envelope.
    Type: Grant
    Filed: March 28, 2003
    Date of Patent: October 18, 2005
    Assignee: Speedline Technologies, Inc.
    Inventors: Gerald C. Pham-Van-Diep, Patsy Anthony Mattero, Randy Leon Peckham, Gary Freeman, Joseph A. Perault, Richard Willshere

  • Cleaning apparatus in a stencil printer
    Patent number: 6626106
    Abstract: An apparatus and method for cleaning excess solder paste that is deposited on a stencil in a stencil printer. The apparatus includes a solvent bath containing a pool of solvent in which a bar is disposed in the solvent bath. The bar rotates in the solvent bath and surface tension between the bar and the solvent causes the solvent to uniformly adhere to the bar. The bar is used to apply solvent to a cleaning material that is used to wipe excess solder paste from the stencil.
