Hi Suganthi,
I am not sure, but during my studies on thermal engineering I remembered the
question ' How to find heat dissipation factor?'. For this we need to know the
heat dissipated by all components( refer datasheet theta JA,JC and the
operating voltage/current rating) on board, surrounding environmental condition
it operates, cooling method provided, Final mounting of the board ( in rack or
individually). Also if any power dissipation injected from adjacent PCBs.
A thermal analysis could help in getting the required results.
Others can add more if I was wrong.
Cheers!
-John.
