Introduction Most Electronics Packaging Engineers and Analysis Specialists have access toa wide range of high quality analysis tools. While a few computer programs useanalytical methods, the majority are based on numerical analysis techniques.Although these programs are becoming easier to use, they typically requireconsiderable skill, and they are certainly capable of producing … [Read more...]
Making surface temperature measurements using liquid crystal thermography
Introduction The development of liquid crystal (LC) based thermography overthe past 30 years has provided thermal engineers with a relatively inexpensivetechnique for visualizing and measuring surface temperature. Engineers andscientists have successfully used LC thermography to investigate various thermalphenomena in a wide variety of applications. These applications … [Read more...]
Evaluation of different heat transfer coefficient definitions
The analysis of convective heat transfer problems pivots on the accurate knowledge of the heat transfer coefficient, h. The heat transfer coefficient is affected by many parameters which have been defined differently by various investigators. for natural convection cases, the temperature distribution is the governing parameter, while for forced convection problems, the fluid … [Read more...]
How to Select a Heat Sink
With the increase in heat dissipation from microelectronics devices and the reduction in overall form factors, thermal management becomes a more a more important element of electronic product design. Both the performance reliability and life expectancy of electronic equipment are inversely related to the component temperature of the equipment. The relationship between the … [Read more...]
Safety tips and techniques for FEA in modeling solids
Using commercially available finite element analysis (FEA) software is easier today than it has ever been. Software vendors have made great progress toward providing programs that are as easy to use as they are powerful. But, in doing so, software suppliers have created a perilous quagmire for unwary users. Some engineers and managers look upon commercially available FEA … [Read more...]
