size, shape, thickness, position, location, and even

board temperature. Other factors are, trace width,

total printed circuit copper area, copper thickness,

single or double-sided, multilayer board and the

amount of solder on the board. The effectiveness

of the PC board to dissipate heat also depends on

the size, quantity and spacing of other components

on the board, as well as whether the surrounding

air is still or moving. Furthermore, some of these

components such as the catch diode will add heat

to the PC board and the heat can vary as the input

voltage changes. For the inductor, depending on

the physical size, type of core material and the DC

resistance, it could either act as a heat sink taking

heat away from the board, or it could add heat to

the board.
