• Evaluation of Plasma Facing Components Thermal Performance by Infrared Thermography (.pdf)
  In powerful fusion devices, plasma-facing components (PFC) have to handle heat fluxes in the range of 10-20 MW/m² at steady state. This high level of thermal performance involves severe engineering constraints and makes the manufacturing challenging. As a consequence, thermal performance evaluation...
• Solar Production Shifts Into High Gear
  connections analogous to those of batteries in series. The resulting strings then are placed on a glass substrate and aligned for straightness. Spire says it has appreciably automated its crystalline cell-soldering operations. "Silicon's thermal coefficient of expansion is essentially zero...
• Solar Production Shifts Into High Gear
  high enough.”. Also, the thinner the wafer, the more problematic are such operations as soldering and laminating. “Contacting very-thin crystalline cells is an engineering concern. In any soldering process steps the thermal expansion of the silicon can be a problem,” says Mitchell. Crystalline...
• When to go Linear
  signals. The signals determine the direction and distance traveled along the band. Linear encoders help minimize errors in motion transmission such as backlash, hysteresis, abbe errors, ball-screw thermal expansion, and other problems. They also find use as motionfeedback sensors in high...
• AN0007 Stack Chip Components Handling and Usage
  the component is shielded from direct. exposure to severe temperature environments. However, the rate of temperature change. should be restricted to < 4OC / second in all cases. The main causes of thermal cracking is mismatched Coefficients of Thermal Expansion. (CTE) between the capacitors...
• Flouroplastics
  extremely high loads. Sliding speed has a marked effect on friction characteristics of unreinforced PTFE resins; temperature has very little effect. PTFE resins have an unusual thermal expansion characteristic. A transition at 65 °F produces a volume increase of over 1%. Thus, a machined part, produced...
• Reinforced Plastics Make Metals Look Weak
  of thermal expansion, stop shrinking once they solidify. Tooling will "trap" the part in the contracting mold perhaps damaging either the mold or part if not accounted for. Ways to combat the problem include removing the molded CFRTP plates at as high a temperature as possible and designing the mold...
• Improving Production Efficiency with Optimal Release Liners (.pdf)
  with. mechanical fasteners. PSAs also allow the joining of both thinner substrate materials and. materials that have different coefficients of thermal expansion. Outsourcing with PSAs. PSAs provide a pre-packaged, ready-to-use solution that allows manufacturers to. essentially outsource the creation...
• Thermoset Composites
  individual filaments; unidirectional, impregnated tapes up to 60 in. wide; multiple layers of tape with individual layers, or plies, at selected fiber orientation; and fabrics of many weights and weaves. The outstanding design properties of carbon fiber/resin matrix composites are their high strength...
• Expanded PTFE Polymer Keeps Electrical and Electronics Cables Clean and Flexible
  thermal insulator in its expanded form. The absence of large functional groups and cross-linking mean the polymer chains tend to slide past each other, leaving the bulk plastic mechanically weak. This weakness lets it absorb mechanical energy and provides a low coefficient of friction. PTFE also tends...
