Thermal analysis of a circuit board

Justin Broughton May 13, 2013 9:23 AM

I can perform thermal analysis of a circuit board for temperatures. However, I'm wondering how I would simulate the circuit board being covered in some type of material that prevents it from overheating (and it could be covered either in an even X mm coat or it could be put into a block of the material of x by y by z dimensions). Would I just make a block around it in Solidworks for the second "block" scenario?

modeling a component and getting it to mesh might be difficult.
consider a thermal resistance or reducing the convection coefficient.
do a test on a sample before you go to your full model.

  @Justin Broughton: I think it is not a good idea to do the thermal analysis of the circuit board covered with the material that prevents the overheating of circuit board because it interfere with the convection and the heat flow by the radiations that affects the result of the analysis, so you should take the board out of the material and then perform the analysis.
