Abstract :
Non-dimensional correlation between Nusselt number (Nu) and Grashoff number (Gr), dedicated to high-density printed circuit board (PCB), was derived in natural convection cooling system. For the verification of the correlation, experimental simulation was performed in basis of several PCB properties. And unique definitions were given to dimensionless numbers.
