Abstract:
Circuits and methods include transmission lines formed from a conductive cladding on a substrate surface. The transmission line includes additional reference conductors positioned co- planar on the surface, including a gap between the transmission line and each of the reference conductors. The transmission line and the reference conductors are at least partially encapsulated (e.g., sandwiched) between two substrates. Isolation boundaries may be included as ground planes, e.g., above and below the transmission line, on opposing surfaces of the substrates, and Faraday walls, e.g., vertically, through the substrates. Current densities generated by various electromagnetic signals are distributed among the transmission line and the reference conductors (as a tri-conductor arrangement), and may be partially further distributed to the isolation (ground) boundaries.

Abstract:
A printed wiring board includes a power supply conductor pattern arranged on one conductor layer, one ground conductor pattern arranged on the one conductor layer, and another ground conductor pattern arranged on the another conductor layer so as to be opposed to the power supply conductor pattern. The power supply conductor pattern includes a power supply pad on which a terminal of a capacitor is to be bonded. The one ground conductor pattern includes a ground pad on which another terminal of the capacitor is to be bonded. A slit is formed in the another ground conductor pattern so as to pass through a projection portion defined by projecting the power supply pad onto the another ground conductor pattern and divide a projection portion defined by projecting the power supply conductor pattern onto the another ground conductor pattern.
Abstract:
The present invention relates to a cliche for off-set printing to form a mesh pattern. More specifically, the present invention relates to a cliché for off-set printing comprising a mash pattern with a plurality of intersection units, wherein the plurality of intersection units are formed in a curved shape with a radius of curvature which is 0.6 to 4 times the width of a mesh line. The use of the cliche for off-set printing according to the present invention can reduce the phenomenon of line width reduction generated around the intersection units during mesh pattern printing. As a result, the final product manufactured using the cliche for printing according to the present invention can have improved surface resistance.
Abstract:
An electric power supply platform (1) made up of an upper conductive layer (2), a lower conductive layer (3), and a non-conductive insulating layer (4) sandwiched between the conductive layers (2), (3). Specially designed light emitting diodes (LEDs) (9) and a variety of other electronic components, each having one short lead (11) and one upper insulated long lead (10), may be removably attached to, displayed, and powered by the power platform (1) simply by inserting leads into the display surface (5) of the power platform (1). The leads of the LEDs (9) and other electronic components are different lengths so that the short lead (11) only comes into contact with the upper conductive layer (2) and the long lead (10) only comes into contact with the lower conductive layer (3) ensuring proper polarity. The leads (10), (11) of the LEDs (9) and/or other electronic components may be inserted into the display surface (5) at any location allowing the user to make any design he/she desires.
Abstract:
Fundamental interconnect systems for connecting high-speed electronics elements are provided. Interconnect system has the means, which could reduce the microwave loss by reducing the effective dielectric loss and dielectric constant of the interconnect system, and increase the bandwidth of the interconnects and also reduce the signal propagation delay, respectively. Ideally, the speed of the electrical signal on the signal line can be reached to speed of the light in the air, and the bandwidth can be reached to closer to the optical fiber. The interconnect systems consists of the signal line, dielectric system with opened trench or slot filled up with the air or lower dielectric loss material, and the ground plan. The signal line proposed in this invention could be made any type of signal line configuration for example, microstripline, strip line or coplanar line. The signal line can also be made as single ended or differential pairs of any configurations. The interconnect system based on the fundamental techniques provided in this invention, can be used for on-chip interconnects where the high speed electronics devices are connected by the signal line laid on the oxide or dielectric material. Again, the interconnect system based on the fundamental techniques provided in this invention, can also be used for off-chip interconnects (chip-to-chip interconnects), where the whole portion or portion of the PCB on which high speed chips are to be connected, are having the dielectric system with opened trench or slot to reduce the microwave loss. High scale chip-to-chip interconnection using of the multilayed PCB is possible. The fundamental techniques provided in this invention can also be used for high -speed connectors and high-speed cables. The main advantages of this invention are to make high speed interconnects systems for on-chip and off-chip interconnects.
