Bringing the Heat

New Thermal Characterization Testing Standard and Tools Allow More Accurate Thermal Analysis for LEDs and Semiconductors By John Parry, Mentor Graphics, Wilsonville, OR LED, semiconductor, and package designers use complex thermal analysis software to analyze their products, but the analysis is only as good as the data provided. Reliable clarification of heat data upstream and downstream is critical. The process of obtaining this clarification traditionally has been cumbersome, requiring manual intervention. But now, for the first time, an automated process combines accurate thermal measurement with precise analysis, giving companies the ability to design better LEDs and power semiconductor device packages, create accurate simulation models, and verify systems for proper heat management.

Improving Software Reliability in Satellite and Spacecraft Applications

In the space industry, much of the effort to refine system engineering processes has been done by hand using tools as divergent as Microsoft PowerPoint to IBM Rational Doors. While these tools are valuable, they do not provide a direct connection to source code and test results.

Solar Cell Manufacturing and Robot Automation: Right Fit, Right Robot

The United States has set 2015 as a goal to reach grid parity (that point where solar electricity is equal to grid electricity). No matter your thoughts on regulatory involvement, it is clear there will be a resurgence in investment, development, and innovation within the PV manufacturing community throughout the world, and it will largely be driven by technology. Finding the most effective tools and processes to gain more productivity and decrease costs within a set capital plan is paramount.

Motion Control and System Engineering Considerations

Motion control choices are best made in light of the whole system architecture, as the selection of system architecture will drive not only the implementation and integration stages of the project, but also manufacturing and field service, and even the ability to ship and install the final product. We will first review a quick tour of system engineering, and then go on to the motion control specifics.
