A glazing includes at least one glass sheet provided on one of the faces with an electrical network having resistance strips and collector strips, in which at least one portion of one face includes at least one strip obtained from an electrically conductive composition including a silver paste, the strip being in contact with another strip obtained from an electrically conductive composition including a copper paste, the other strip obtained from an electrically conductive composition including a copper paste being completely covered with a protective enamel layer.

It is desirable to improve a longevity and reliability of a substrate used within an IC package. By modifying a design of the one or more layout masks used to create planes within a substrate, the resulting planes may have a non-straight pattern on the edges of each plane and may include a predetermined pattern of open spaces filled with dielectric materials in each plane. The improved mechanical strength of the patterned planes can effectively compensate the effect of mismatched thermal expansion during IC testing and deployment, resulting in increased durability and longevity of the package substrates.

A method for fabrication includes providing a donor sheet, including a donor substrate, which is transparent in a specified spectral range, a sacrificial layer, which absorbs optical radiation within the specified spectral range and is disposed over the donor substrate, and a donor film, which includes a paste and is disposed over the sacrificial layer. The donor sheet is positioned so that the donor film is in proximity to a target location on an acceptor substrate. A pulsed laser beam impinges on the sacrificial layer with a pulse energy and spot size selected so as to ablate the sacrificial layer, thus causing a viscoelastic jet of the paste to be ejected from the donor film and to deposit, at the target location on the acceptor substrate, a dot having a diameter less than the spot size of the laser beam.

System with at least two layers as a mean or system for transferring electrically conductive ink adapted to receive and transfer said ink on a textile substrate by a thermal transfer.

A method is disclosed for applying an electrical conductor to a solar cell, which comprises providing a flexible membrane with a pattern of groove formed on a first surface thereof, and loading the grooves with a composition comprising conductive particles. The composition is, or may be made, electrically conductive. Once the membrane is loaded, the grooved first surface of the membrane is brought into contact with a front or/and back of a solar cell. A pressure is then applied between the solar cell and the membrane(s) so that the composition loaded to the grooves adheres to the solar cell. The membrane(s) and the solar cell are separated and the composition in the groove is left on the solar cell surface. The electrically conductive particles in the composition are then sintered or otherwise fused to form a pattern of electrical conductor on the solar cell, the pattern corresponding to the pattern formed in the membrane(s).

A printer is configured for printing with conductive ink for applying a conductive pattern to a surface including a wheeling structure for moving the printer over the surface and a transfer unit for applying a layer of electrically conductive ink to the surface. To provide accurate printing with the ability to obtain fine tolerances, the transfer unit has a printing drum rotatable about a printing drum axis and defining a printing drum periphery moving between a first zone and a second zone by rotation of the printing drum. The printing drum periphery, in the first zone, receives the conductive ink and in the second zone transfers the ink to the surface.

It is proposed to provide a transfer method of a high viscosity functional material, such as a conductive paste, onto a receiving substrate, the method comprising the steps of: providing a plate having a cavity surface that includes at least one cavity; providing the cavity with a resistive heating device and control circuitry connected to the heating device; providing a functional material in the at least one cavity, having a material composition that, when heated by the heating device, generates a gas at an interface between the cavity surface in the cavity and the functional material, to transfer the functional material from the at least one cavity by the gas generation onto the receiving substrate.

Apparatus and methods of applying a pattern onto a web with improved uniformity are provided. One or more micro-contact printing stamps are disposed onto a roll with a seam between each adjacent stamp edge. The micro-contact printing stamps are configured and arranged such that the web always contacts the micro-contact printing stamps to provide a consistent contacting pressure to drive the roll.

Research on practical realization of various types of printable devices has progressed, and the realization of devices in which these printable devices are integrated on a flexible board is expected. However, there is the problem that, if a plurality of printable devices are simply integrated on the same board, the area of the integrated device increases, and the yield ratio greatly decreases. An integration technique that solves the problem of an increase in the area and a decrease in the yield ratio is in demand. Electronic devices to be integrated are formed on individual boards, the boards are laid to overlap each other in a predetermined relationship, and then through-vias are formed at predetermined positions. With this, the electronic devices are electrically connected to each other, and function as an integrated device.

According to the present disclosure, a support structure for lighting devices, e.g. LED lighting devices, is provided with an electrically insulating core layer having a first and a second mutually opposed surfaces, with mounting locations for electrically-powered light radiation sources on the first surface, a network of electrically conductive lines printed on said first surface, at least some of said electrically conductive lines extending between the mounting locations and fixed locations on the first surface, and electrical distribution lines of electrically conductive material on the second surface of the core layer, and electrically conductive vias extending through core layer and electrically coupling the electrical distribution lines on the second surface with the electrically conductive lines at said fixed locations on the first surface.
