  • Publication number: 20150024119
    Abstract: A method and an arrangement are disclosed for transferring electrically conductive material in fluid form onto a substrate. Said substrate is preheated to a first temperature, and of said electrically conductive material there is produced fluid electrically conductive material. The fluid electrically conductive material is sprayed onto the preheated substrate to form a pattern of predetermined kind. The substrate onto which said fluid electrically conductive material was sprayed is cooled to a third temperature, which is lower than the melting point of said electrically conductive material.

  • Publication number: 20150017341
    Abstract: A method and an arrangement are disclosed for producing an electrically conductive pattern on a surface. Electrically conductive solid particles are transferred onto an area of predetermined form on a surface of a substrate. The electrically conductive solid particles are heated to a temperature that is higher than a characteristic melting point of the electrically conductive solid particles, thus creating a melt. The melt is pressed against the substrate in a nip, wherein a surface temperature of a portion of the nip that comes against the melt is lower than said characteristic melting point.

  • Patent number: 8654502
    Abstract: An apparatus, a method, a planar insulating substrate and a chipset have been presented, comprising at least one module configured to establish a predefined pattern on a planar insulating substrate so that conductive particles can gather according to the predefined pattern. At least one another module is configured to transfer the conductive particles to the planar insulating substrate, wherein the conductive particles are arranged to gather according to the predefined pattern. A sintering module is configured to fuse the conductive particles on the planar insulating substrate, wherein the conductive particles are arranged to fuse according to the predefined pattern to establish a conductive plane on the planar insulating substrate. Embodiment of the invention relate to printable or printing electronics on a fibrous web.

  • Publication number: 20130255079
    Abstract: A chip is attached to a printed conductive surface. The chip is first heated to a first temperature, which is lower than what the chip can stand without being damaged by the heat. The heated chip is pressed against the printed conductive surface with a first pressing force. A combination of said first temperature and said first pressing force is sufficient to at least partly melt the material of at least one of: the printed conductive surface, contact point on the chip.

  • Patent number: 8493421
    Abstract: Packages are manufactured in a digitally controlled process. A digital printing machine (101) produces printed workpieces and a cutting machine (104) cuts packaging blanks (105) from them. A conveyor line (107) transfers the printed work-pieces automatically from the digital printing machine (101) to the cutting machine (104). A digital control system (109) exchanges digital control information with at least the digital printing machine (101) and the cutting machine (104).
