IP to the Pin is a software technology that will significantly influence automated test in the coming one to three years, according to National Instruments’ 2011 Automated Test Outlook, a view of key technologies and methodologies impacting the test and measurement industry. Sharing FPGA IP between design and test will dramatically shorten design verification/validation and … [Read more...]
Calculation Corner: Thermal Interactions Between High-Power Packages and Heat Sinks, Part 2
These days, many thermal engineers face the challenge of defining effective heat sink cooling solutions for high power processors and ASICs (Application-Specific Integrated Circuits). The usual practice would be to calculate a value of ΘJA (junction-to-air thermal resistance) for the combined package/heat sink assembly and compare it to the requirements of the … [Read more...]
Ultrafast Submicron Thermoreflectance Imaging
K. Yazawa and A. Shakouri Baskin School of Engineering, University of California at Santa Cruz, California Both the miniaturization of electronic and optoelectronic devices and circuits and the increased operation speeds of electronic devices have exacerbated localized heating problems. Steady-state and transient characterization of temperature distribution in devices … [Read more...]
Reasons to Use Two-Phase Refrigerant Cooling
Water-cooling at the rack appears to be the new short-term technological solution for server cooling in datacenters, with its advantages over traditional cold aisle/hot aisle air-cooling being clear, as can be seen in [1]. Bringing chilled water to the rack and then cooling the air inside the rack aids with the transport of energy across the datacenter, making the necessity for … [Read more...]
Cooling Fans Work Harder when Contamination Accumulates on Circuit Boards
Contamination accumulated on electronic circuit boards will cause temperatures in electronics to rise, triggering cooling fans to work harder to keep the equipment below its operating temperature limit, according to a new research paper by 8 Solutions. Untreated contamination is costing the data centre industry millions of pounds each year, the authors say. The study, which … [Read more...]
