Microelectronics and microsystems play a vital and increasingly important role in current and future human life and society. The future will bring a plethora of new products/processes based on new concepts with limited past experience to build upon. Much of the research of microstructures involves thermal management in one way or another, such as in relation to the biochemistry … [Read more...]
Spreadsheet Based Thermal Resistance Analysis Part 2: Generating the Thermal Resistance Matrix
The first article in this series on spreadsheet based thermal resistance network analysis [1] described a procedure for using Microsoft Excel to solve a thermal resistance network by applying matrix analysis. That article assumed that the values of the thermal resistances between nodes were both known and fixed. This article presents methods for simplifying the process of … [Read more...]
Nanotechnology Converting a Car’s Waste Heat into Electrical Power
Up to 60 percent of each $4 gallon of gas is wasted, lost as heat that pours out of the exhaust pipe. The technology to collect some of that heat and convert it back into electricity that can recharge the battery exists, but it’s still a work in progress. The solution lies in thermoelectric devices. A material whose response to a change in temperature generates electric … [Read more...]
Thermal Management PCBs Solve Thermal Problems for LED Industry
SinkPAD Corporation’s new SinkPADTM aluminum PCB technology are a complete and effective solution to the challenges faced by the solid state lighting industry, specifically those with aluminum LED PCB applications. SinkPADTM conducts heat out of the LED system (LED conduction cooling) by enabling a direct thermal path between the LED and surrounding atmosphere. The LED thermal … [Read more...]
Compact Linear Laser Diode Driver Supports Fiber-Coupled Lasers
Wavelength Electronics’ PLD-CH Series is now available in a 12.5 A model. This new driver supports fiber-coupled lasers used in applications such as medical, dental, micro-machining, material processing, semiconductor inspection, and imaging. The PLD-CH Series offers single-supply low voltage operation from +5 V DC, which minimizes heat dissipation. For applications that … [Read more...]
