  • Patent number: 9730333
    Abstract: A solution of metal ink is mixed and then printed or dispensed onto the substrate using the dispenser. The film then is dried to eliminate water or solvents. In some cases, a thermal curing step can be introduced subsequent to dispensing the film and prior to the photo-curing step. The substrate and deposited film can be cured using an oven or by placing the substrate on the surface of a heater, such as a hot plate. Following the drying and/or thermal curing step, a laser beam or focused light from the light source is directed onto the surface of the film in a process known as direct writing. The light serves to photo-cure the film such that it has low resistivity.

  • Publication number: 20150155127
    Abstract: A neutron generator includes carbon nanotubes that function as the anode and provide deuterium storage. The ionization source includes a layer of carbon nanotubes that provides a pulse of deuterium ions through field-induced desorption and ionization of deuterium atoms on the surface or retained in the bore of the nanotubes. A high-yield (>1010 n/s) neutron generation is achieved by employing a field desorption ion source and applying an electric field of 10-40 V/nm. Such high fields may be achieved with carbon nanotubes having high aspect ratios with field enhancement factors on the order of 1000. By operating the ion source in a background pressure of deuterium or hydrogen, the gas adsorption on the nanotubes may be regenerated after each pulse.

  • Publication number: 20150040388
    Abstract: A dielectric layer is directly applied onto the surface of a heat sink part. For example, the composition for making the dielectric layer may be made into a paste or ink and then printed as a paste or ink, or applied with some other equivalent method, such as a lamination technique. The electrical circuit traces are then printed in a similar fashion onto the dielectric layer in the required pattern for whatever circuitry is to be applied. That circuitry (e.g., circuit elements) is then attached to the electrical traces as needed for the particular application.

  • Publication number: 20140216799
    Abstract: An object is to provide a conductive film forming method which can form a conductive film having low electric resistance on a base material by utilizing photo sintering even when the base material has low heat resistance. A conductive film forming method is a method in which a conductive film is formed on a base material, and the method includes the steps of forming a film composed of copper particulates on a base material, subjecting the film to photo sintering, and applying plating to the photo-sintered film. Whereby, it is possible to form a conductive film on a base material by lowering irradiation energy of light in photo sintering even when the base material has low heat resistance. Since the conductive film includes a plated layer, electric resistance decreases.

  • Patent number: 8647979
    Abstract: Conductive lines are deposited on a substrate to produce traces for conducting electricity between electronic components. A patterned metal layer is formed on the substrate, and then a layer of material having a low thermal conductivity is coated over the patterned metal layer and the substrate. Vias are formed through the layer of material having the low thermal conductivity thereby exposing portions of the patterned metal layer. A film of conductive ink is then coated over the layer of material having the low thermal conductivity and into the vias to thereby coat the portions of the patterned metal layer, and then sintered. The film of conductive ink coated over the portion of the patterned metal layer does not absorb as much energy from the sintering as the film of conductive ink coated over the layer of material having the low thermal conductivity. The layer of material having the low thermal conductivity may be a polymer, such as polyimide.
