Abstract
A circuit board includes an upper circuit and a lower surface that are opposite to each other, a plurality of heat sink bonding pads, and a plurality of heat sink conductive pads. The heat sink bonding pads are disposed on the upper surface and electrically insulated from one another, and are used to electrically connect to a heat sink. The heat sink conductive pads are disposed on the lower surface, electrically insulated from one another, and electrically connected to the heat sink bonding pads, respectively.
