  • Print head for stencil printer
    Patent number: 9126280
    Abstract: A stencil printer for printing viscous material on an electronic substrate includes a stencil having apertures formed therein, and a print head positioned over the stencil and configured to deposit viscous material within the apertures of the stencil. The print head includes a housing defining an elongate chamber, a source port defining a passage having an inlet positioned to allow viscous material to flow into the elongate chamber, a pair of blades defining a slot that provides an outlet from which viscous material can flow out of the elongate chamber, an elongate plunger movable in the elongate chamber to reduce a volume of viscous material within the elongate chamber, and at least one sensor to detect pressure of the viscous material within the elongate chamber.

  • METHOD AND APPARATUS FOR PRINTING SMALL ASPECT FEATURES
    Publication number: 20150090134
    Abstract: A method of stencil printing small aspect features includes performing a stencil print stroke across a stencil having at least one small aspect opening with a stencil printer having a squeegee blade, and venting an area below the at least one small aspect opening. Another method includes performing a stencil print stroke across a stencil having at least one small aspect opening with a stencil printer having a multi-blade squeegee, and venting an area below the at least one small aspect opening. A stencil printer includes a stencil having apertures formed therein, and a print head positioned over the stencil and configured to deposit viscous material within the apertures of the stencil. The print head includes a support, a first pair of blades secured to the support, and a second pair of blades secured to the support.
