Claim 2:
3. The circuit board of claim 1, wherein:
the circuit board is disposed in a heat-dissipation air duct comprising an air inlet;
for at least one row of heat-generating components, spacing between a first heat-generating component and a second heat-generating component is smaller than spacing between the first heat-generating component and a third heat-generating component;
the first heat-generating component is a leading heat-generating components closest to the air inlet;
the first heat-generating component and the second heat-generating component are neighboring heat-generating components in the same row; and
the first heat-generating component and the third heat-generating component are neighboring heat-generating components in a first column of heat-generating components.
