  • High quality, high density, and well-aligned zinc oxide (ZnO) nanorods have been synthesized on cost-effective printed circuit board (PCB) substrates via a simple, seedless, onestep, low-temperature hydrothermal method based galvanic cell structure. It was found that the outer diameters of the ZnO nanorods range from 50 nm to 400 nm.

  • They now include finer conductor tracks and thinner laminates, present in an ever-increasing number of layers. Integrated circuits have become dramatically sophisticated especially in the last decade. This has in turn created new design requirements for mounting them on the boards. While insertion was common with DIP (dual in- line-package) technology in the 1970s, surface mount technology in now being increasingly employed. holes is increasing; and hole diameters are rapidly decreasing.

  • The relationship between the manufacturers of electronic components and the assemblers of electronic circuitry resembles that between two different orders of living beings, for example insects and plants: they need one another to be able to exist, and for that reason there are close links between the evolutionary paths of both. The shapes and the dimensions of their bodies, or respectively their functions, must match one another, so that whatever is needed to ensure the survival of either species can be properly performed. Any mistakes or mismatches are punished by extinction....

  • PRINTED CIRCUIT Processes & Instructions Why make a PC Board?? This may sound like a strange question, considering that we are promoting PC board making products here. However, there are times when a PC board is not necessary and may require a lot more time than you want to spend. A PC board will provide repeated accuracy for any quantity of the same board, but if you are making just one, why not use a Protoboard instead?

  • Circuit connections to the DAQ require a cable and a facility for connecting to individual pins. An efficient system is based on a National Instruments Connector Block (CB-68LP) and a basic circuit board as shown here. Connections to the circuit board from the connector block are made one time. The two resistors of the circuit are connected to output channels 0 and 1, respecively. Thus, for example, Chan0_out, as noted, is dedicated to the top strip on the circuit board. The bottom top strip is associated with Chan0_in, and so forth....

  • Most people look at an electronic circuit diagram, or a printed circuit board, and have no idea what they are. One component on the board, and one little squiggle on the diagram, looks much as another. For them, electronics is a black art, practised by weird techies, spouting untranslatable jargon and abbreviations which make absolutely no sense whatsoever to the rest of us in the real world.

  • A control system is a collection of components working together under the direction of some machine intelligence. In most cases, electronic circuits provide the intelligence, and electromechanical components such as sensors and motors provide the interface to the physical world. A good example is the modern automobile. Various sensors supply the on-board computer with information about the engine’s condition. The computer then calculates the precise amount of fuel to be injected into the engine and adjusts the ignition timing. T...

  • This tutorial presents an introduction to Altera’s SOPC Builder software, which is used to implement a system that uses the Nios II processor on an Altera FPGA device. The system development flow is illustrated by giving step-by-step instructions for using the SOPC Builder in conjuction with the Quartus R II software to implement a simple system. The last step in the development process involves configuring the designed circuit in an actual FPGA device, and running an application program.
