Issues with thermal simulations

[sacarlos]

I have done a basic simulation which consists on a chip (10W) over a board at 25

Use the thermal properties of G10 fr4 fiberglass PCB material. If you need the data use matweb. The thermal properties I have for g10 are:






Thermal Conductivity
0.288 W/m-K
2.00 BTU-in/hr-ft
