The Thermal Analyzer is intended to be used for analyzing and identifying potential thermal problems on a Printed Circuit Board. It evaluates the Temperature Distribution on a finished PCB, at steady state conditions. The result of the analysis may be displayed using isotherms or color mapping scheme.
Steps for Thermal Analysis
1. Right click on the
in the Project Explorer. Select
in the list.
2. Select the
to open the settings window and click the
Options tab. Click on Set to default button .
4. From the
select Settings click and select the
Click on Set to
5. After supplying necessary parameters,right click and select the tool
Execute to execute the analysis. The result is displayed in the form of isotherms.
6. Color mapping of the board may be viewed by switching on the option
View- >Analysis Results->Colored board.
7. 3D Board may be viewed by switching on the option
View->Analysis Results->3D Board Viewer.
This option allows to view the temperature distribution on the circuit in the form of a
The higher the temperature, the higher will be the location of the point on the graph.
8. The analysis result is obtained. From the result it may be easy to identify the most heated up component so a heat sink of about may be used.
9. To simulate the heat sink effect, Select the tool
and click on the component. A
window pops up where you may set the cooling parameter for the component. Check
Component Mounted Heat Sink
check box, enter the Thermal Resistance of Heatsink (e.g. 1.2°C/Watt) value and click
10. Repeat the same step for all other components and execute the analysis again. You can notice the change in the isotherms after conducting the thermal analysis in the figure given below.
11. Labels may be placed to display the temperature at various points on the board. For this right click and select the tool
Label and click on the board at required locations. Label gets tagged to the cursor. Now drag the mouse to place the label at proper place.
Note: To delete the isotherm label click again on the label.
