Temperature thresholds in electronics cooling

The Temperature threshold is the temperature at, or above, which the component may be at risk of failure due to overheating. You can set a Temperature threshold on at risk board components to highlight their risk of failure.

On PCB boards, there are various components which heat up and dissipate heat as a result of the applied heat load. Above a certain temperature, these components may overheat and could risk failing as a result. The applied load and the maximum temperature of these components are listed on the manufacturer's specification sheet.

Note: When you create your electronics board the Fusion Electronics workspace, MAXTEMP attributes you set on the 2D layout are imported into the Simulation workspace automatically as Temperature thresholds.

When you set a Temperature threshold, a Threshold result is produced that shows you the temperature of all the components. This result indicates how close those components with specified temperature thresholds are to their respective thresholds.

Note: You are not required to set a Temperature threshold on the board components, but the Threshold result is generated only when you do specify temperature thresholds.
