Abstract
A motherboard includes a printed circuit board (10), and at least a power/ground trace (20) formed on the printed circuit board. The trace includes a pair of main lines (14, 24) and at least a protection line (12, 22) connected between the main lines. A width of the main lines is constant and wider than of the protection line. Wherein when a current flowing through the power/ground trace exceeds a maximum current the protection line can endure, the protection line is burnt and disconnected from the main lines, thereby generating less smoke and protecting components connected with the trace of the motherboard from damage due to excess current.
