[SI-LIST] Re: Heat Dissipation Factor

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.
