  • Patent number: 9359765
    Abstract: A high speed granule delivery system and method is disclosed for dispensing granules in intermittent patterns onto a moving asphalt coated strip in the manufacture of roofing shingles. The system includes a granule hopper and a rotationally indexable pocket wheel in the bottom of the hopper. A series of pockets are formed in the circumference of the wheel and the pockets are separated by raised lands. A seal on the bottom of the hopper seals against the raised lands as the wheel is indexed. In use, the pockets of the pocket wheel drive through and are filled with granules in the bottom of the hopper. As each pocket is indexed beyond the seal, it is exposed to the moving asphalt coated strip below and its granules fall onto the strip to be embedded in the hot tacky asphalt. Well defined patterns of granules are possible at high production rates.

    Abstract: An integrated circuit screen printing nozzle that has a nozzle body, a first inner layer on the nozzle body, a second outer layer on the first layer, and an opening through the nozzle body, the first layer, and the second layer. The first and second layers can be an insert held within the body. The opening allows paste material to flow through the screen printing nozzle to the stencil mask. Also, the second outer layer includes a contact surface adapted to contact the stencil mask. One feature of the invention is that the first layer is softer (has a lower durometer) than the second layer. This allows the second layer to be more durable than the first layer and for the first layer to provide additional flexibility to the second layer. Therefore, the invention provides a nozzle that has the high durability characteristics of a hard outer surface with the compliance of a soft nozzle.

  • Patent number: 6997107
    Abstract: A cream solder cartridge used in a screen printing apparatus which prints cream solder on a board through pattern holes by sliding, on a mask plate, a closed squeegee that is stored with cream solder inside is composed of a long and narrow concave portion made of a flexible film-like material, a brim portion projecting from the outer periphery of the concave portion, and a film-like cover sheet that is stuck to the brim portion and thereby closes the opening of the concave portion. This configuration makes it possible to supply paste at a low cost and to perform a viscosity adjustment easily by externally stirring the paste accommodated inside.

  • Patent number: 6981859
    Abstract: The object of the present invention is to reduce irregularity of the amount of applying of the conductive paste applied for forming the side face electrode so as to be extended from a part of the side face of the component body up to a part of the face adjoining the side face, wherein the conductive paste is filled into the slit provided on the slit plate, and the component body is disposed with its side face toward the first principal face side of the slit plate, followed by allowing the shutter member to undergo elastic deformation toward the inside of the slit by compressing the shutter member comprising an elastic material with a projection on the compression member, thereby the conductive paste is applied so as to extend the paste from a part of the side face of the component body up to a part of the faces adjoining the side face while supplying the conductive paste on in the slit so as to swell on the first principal face.

  • Patent number: 6890384
    Abstract: A method and apparatus for achieving a level exposed surface of a viscous material pool for applying viscous material to at least one semiconductor component by contacting at least a portion of the semiconductor component with viscous material within a reservoir. A level viscous material exposed surface is achieved by using at least one mechanism in association with the reservoir. The mechanism is configured to level the exposed surface of viscous material and maintain the exposed surface at a substantially constant level. The reservoir may be shaped such that the exposed surface of viscous material is supplied to a precise location.

  • Patent number: 6814804
    Abstract: A filling squeegee and a scraping squeegee are provided in a printing apparatus. The filling squeegee is moved without contacting a surface of a mask in order to fill a solder paste into openings of the mask. Unnecessary solder paste on the surface of the mask is scraped by the scraping squeegee. The solder paste is prevented from being improperly filled in or scraped from the openings even if a speed of the squeegee is increased, so that the solder paste can be printed stably on circuit board.

  • Patent number: 6730170
    Abstract: An encapsulant applicator comprising a flexor formed of a resilient material and a substantially rigid blade is described. The blade is attached to the flexor in a way that during a smoothing process, a force applied through the flexor is distributed across the second edge of the blade. Another aspect of the invention pertains to a system for forming a substantially uniform layer of material on a surface of a semiconductor wafer. The system of the present invention includes a stencil, an applicator and a conveyor device. The stencil is placed over the surface of the wafer so that an opening in the stencil exposes a portion of the surface of the wafer. The conveyor device is connected to the flexor so that during the smoothing process, the conveyor device moves the applicator across the opening of the stencil. Yet another aspect of the invention pertains to a method for applying a substantially uniform layer of flowable material to a surface of a semiconductor wafer using the applicator as described.
