• Tin Vs. Bare
  an electrical signal; we're talking about the metals conductivity. When restoring the bridge in the center of town a little surface rust may not be a big deal, just sand it off and re-paint. Conversely, a quality, non oxidized finish on the surface of a copper conductor is paramount to good electrical...
• 270-Volt DC Contactor Solves Costs vs Performance Problems
  Aircraft requiring greater electrical power for an increasing number of critical electrical loads are employing 270Vdc power. But to make, break or change the connection of electric circuits for the high voltage poses a significant challenge for the manufacturers of relays and contactors. Various...
• Surface Enhancements Eliminate ESD Damage During Operation of State-of-the-Art I.C. Handlers
  resistance, lubricity, and electrical conductivity. Even extremely thin deposits of the NEDOX coating act as a static barrier, preventing static build-up and the resultant ESD.In the HCR surface enhancement process, aluminum in the substrate surface is converted to aluminum oxide. The H2O...
• MICRO: Expansions
  say that the high electrical and thermal conductivity and tensile strength of carbon nanotubes make them attractive for electronic device applications, properties that enable possible performance breakthroughs through incorporation into existing chips as well as in the development of future...
• Guided Wave Radar at Genentech: A Novel Technique for Non-invasive Volume Measurement in Disposable Bioprocess Bags
  with transmitter. (d) Kistler Morse LD3-02K-X-015-X-X (4 load cells). Guided wave radar is based upon the principle of time domain reflectometry (TDR). TDR is a measurement technique used to determine the characteristics of electrical lines by observing reflected waveforms Pulses of electromagnetic...
• MICRO:Building Copperopolis, by Bruce Maeda, p.39 (Sept '99)
  concentration of electrolyte.3 The optimal metal deposition rate can be controlled by maximizing cathode surface area, bulk mixing, and electrical current efficiency. To maximize copper removal, the recovery system uses reticulated cathodes, which provide a high surface area in a smaller package than...
• A Modular Approach to Process Analysis
  a reaction," he adds. "We are following developments with the NeSSI initiative through our participation in CPAC and are anxious to test these devices once microanalytical tools become available." Other compelling possibilities are a single NeSSI instrument that combines many different spectrometers or one...
• Metrigraphics Article in Today's Medical Developments
  blanket coatings on devices to very precise pattern coating and other structural devices for satellite-based portions of the aerospace industry and test devices launched into space. The space application mentioned included a solid gold sheet with very precise slits in it that were electroformed...
• The Benefits of Designing & Testing a Low Resistance Grounding System
  conductor. Soil Resistivity Measurements. To determine the conductivity of the soil, a four-point ground meter is utilized (Figure 2). This test requires the user to place four equally spaced auxiliary probes into the earth to determine the actual soil resistance, traditionally in ohms-cm. This test must...
