Abstract:
Systems and methods are provided for producing functional printed circuit boards. It is intended that the systems and methods described herein will allow the production of functional PCBs in a more efficient and less labor- and equipment-intensive manner than may be obtained using conventional production methods. The produced functional PCB would have the required mechanical, thermal, electrical, etc., characteristics enabling it to function in a manner corresponding to a design characteristics of a conventional PCB.
Abstract:
This invention relates generally to uses of novel nanomaterial composition and the systems in which they are used, and more particularly to nanomaterial compositions generally comprising carbon and a metal, which composition can be exposed to pulsed emissions to react, activate, combine, or sinter the nanomaterial composition. The nanomaterial compositions can alternatively be utilized at ambient temperature or under other means to cause such reaction, activation, combination, or sintering to occur.
Abstract:
A method and a device for depositing a metal layer on a non-conducting surface of a substrate. (a) A liquid composition containing metal ions is directed to at least a part of the surface and (b) a reductive agent is directed to at least a part of the surface. The metal ions are reduced in situ into the metallic form in those parts onto which both (a) and (b) have been directed. The reduction reaction and the adherence to the non-conducting surface is supported by treatment with physical energy such as treatment with corona discharge, atmospheric plasma, flame treatment, microwave, infrared light and/or UV light. Selective surface treatment is obtained based on electroless plating whereby the surface is printed on with metal and reducer as ink by conventional printing such as inkjet printing and tampon printing electrodes and conducting surfaces with Cu, Ni, Au and Ag.
Abstract:
A CAD controlled circuit board printer for the in-house production of prototype PCBs. The printer (2) includes pneumatically controlled drilling means (12) for cutting grooves and holes in a substrate (8); a deposition system (10) for filling the grooves and holes with a curable polymeric, conductive ink and an oven for curing the conductive material. A pressing means (16) is also provided for the production of multilayer boards. Substrates are cut and filled with conductive ink which are then cured. For multilayer boards, after lamination by the pressing means, holes are redrilled and refilled to enable the formation of continuous conductive pathways between layers. The printer can be used to provide a single board or multiple boards. Various embodiments of the invention are described.
Abstract:
Process for the production of a multilayer printed circuit board composed of a plurality of so-called inner layers, each consisting of an insulating base of thin laminate of reinforcement material impregnated with thermosetting resin. The laminate is preferably provided with a layer of metal or metal alloy on both sides, in which layers a wiring pattern has been formed. Prepreg sheets of reinforcement material impregnated with thermosetting resin are placed between the inner layers. The resin is not fully cured. The inner layers are centered in respect of each other and fixed in this position by pressing the different sheets together along the long sides. Energy is then supplied within a limited area along the two long sides. Thereby the resin is heated and cured so that all sheets are bonded together with each other, preferably in a few spots or minor areas. The package obtained is then laminated under heat and pressure together with conventional outer layers and/or foils of metal or metal alloy to a multilayer printed circuit board which is then completed in the usual way.
Abstract:
Conductive traces and patterns of same are used to bond components together via electromagnetic radiation. Each conductive trace is configured to resonate and heat up when irradiated with electromagnetic radiation, such as microwave energy and/or RF energy, having a wavelength that is about 2.3 times the length of the conductive trace. The conductive traces may be arranged in a pattern to uniformly heat a target area of a substrate or other component to a selected temperature when irradiated with electromagnetic radiation.
