There is more than power dissipation<\/b><\/p>\n

The temperature of a component depends on its power dissipation (Watt), its foot- print area\u00a0 and the heat spreading<\/strong> capability of layer copper and FR4 in the PCB. Only in special academic setups it is possible to estimate the temperature from tables or with a pocket calculator. For better results you have to take into account the layout<\/a> geometry using traces, planes and vias.<\/p>\n

\"trm_intersil_comparison\"<\/a>You have to take into account some details<\/b>
\nUsing TRM<\/b><\/span> (Software \"Thermal Risk Management\") you can perform detailed<\/strong>\u00a0 3-dimensional temperature calculations. The board model is assembled from\u00a0\u00a0 Gerber files<\/strong> or self-made patches, drill files and assembled by graphical means or placement files. Many more features can be added with the user interface. The resolution in x-y direction typically is of the order of 0.1 mm to 0.2 mm. In addition to heated components electric trace heating (Joule heating) can be treated simultaneously.<\/p>\n

Component temperature\u00a0 influences function<\/strong>
\nVoltage drop can substantially depend on the local temperature of the trace (due to T-dependency of electric resistance) either by heating by current or by heating of nearby components. Many other component performance characteristics are also a function of component temperature.<\/p>","protected":false},"excerpt":{"rendered":"
